This happened during production, and the PCB silk screen is actually reversed, too. So if you properly adhere to the silk screen during the capacitor replacement, you will actually repeat their mistake - which has me worry quite a bit as I have done tons of these repairs withough knowing. The fact that these capacitors are the ones that lead the statistics when it comes to leaked caps in the SB3 also confirms they have issues. Using a bipolar cap instead means that there is still the capacity demanded by the circuitry but the part won't suffer from reverse polarity because that's something that cannot happen in a bipolar capacitor.

Re: [slim] New approach to dead Boom / SB3 (Classic) / Transporter
Hey all, just wanted to let you know that the bipolar electrolytics are doing a great job. I have compared to an SB3 with regular capacitors, having both play a 1kHz sine wave in sync, and there is no measurable difference between them. Unfortunately, I forgot to measure voltages across the capacitor pads before actually putting the capacitors back in. Sorry about that. Will do that with the next repair as the device that was under repair recently is already going back to its owner. Cheers, Joe PN me if your Boom / Classic / Transporter display has issues!

I think I'm going to go with a bipolar electrolytic, incidentally I happend to find 10V/16µF in my parts store, so why not. Will check if there is any effect on the audio spectrum but I wouldn't expect a huge difference. Voltage measurements without caps in place will also follow.

Logitech used Panasonic, and all Slimdevices SB3s I have seen (which are quite a lot) also used them. Not sure about the series though, I have found FC, FK, FP, FT, and HB, and it seems to vary a bit from lot to lot. Certainly not the worst choice they could have made, still if they are reversed that's a good explanation for their failure. I have not a lot of knowledge around these things, which of the capacitors are reversed in your opinion? I can say for sure that the silk screen has been the same forever, and it could point towards a design fault that the capacitors are reversed in the silk screen as well as in the pick-and-place process. Even if you are not using your DAC, the Xilinx chip is still talking to it, and if the DAC power supply is unstable thanks to dead capacitors, that will bring the entire system down and have it do a reboot. Hence, no matter what output you are using, the DAC needs to be happy so things are working out. It certainly helps a lot to power the SB3 only when needed, as you say, for the display as well as the capacitors. It's a bit less flexible but should be a concern, now that we are thinking a lot more about our consumption bills. PN me if your Boom / Classic / Transporter display has issues!

[slim] New approach to dead Boom / SB3 (Classic) / Transporter
Hi all, just wanted to let you know that I had some interesting experiences recently. It started with a shock when once again I had done SMD capacitor replacement on multiple SB3s and the dropout rate was extreme. Five separate devices, all would boot but crash and reboot once they were commanded to start playback. Three of them "died" somewhere between the moment I detached the CPU board to do the capacitor replacement and the moment I put it back together to test. Three! They would do what every dead SB3 does, show a very dim TOSLINK, no connectivity, no display. And that despite the fact I hardly ever touched the CPU board at all. I still can't explain how it got to this three times in a row (even five times in a row earlier which had me so depressed I would almost quit). I wore a grounding wrist strap all the time. I discharged the capacitors before replugging the CPU board. Used current limiting for the first startup to ensure that a short won't blow anything up. Used an IR camera to look for hotspots during powerup. So that was a bit awkward. The devices were sent to me for repair and shortly after the repair they would fail and be much worse than they initially were. One of them had run a firmware update, then restarted and was normal for a short period of time before it failed. Which brought me to an idea. Just out of curiosity I extracted the Flash EEPROM from one of them and put it in my reader. Compared to a known-working SB3 there were a lot of differences, at least in the first blocks and, expectedly, where the configuration is held. But I would not assume that the bootloader or whatever is read first from the Flash is very different between identical devices. So I attempted to flash the working image to the EEPROM that was suspected corrupt, with erase first and eventual verification of course to ensure that it isn't the chip itself that is at fault. Then soldered the chip back in and, what do you know, two out of three SB3s were recovered! A Boom PCB is under repair currently, I'll try the same thing there as the hardware arrangement around the CPU is similar to that of the SB3. It looks like what I used to call "CPU death" actually isn't the CPU but the Flash memory for some reason. I don't know why it happens. It should only be written to during configuration and during firmware updates, but something during the repair seems to cause a partial corruption. It's a pity that the EEPROM needs to be desoldered and put back in place as this can only be done once or twice before the board gets damaged. But it's way better than attempting to reflow the CPU which I never succeeded at, and most of the time it might not even be the component at fault. The EEPROM is not easy to handle thanks to its 0.5mm (or so) pin pitch but way easier than the BGA stuff under the CPU. I have too little experience yet to document this or proclaim it as one of the first measures to fix, and due to the complexity of the operation it should rather be considered a last stand, but still. There is a lot of new hope for the stack of failed SB3s and Booms I have around, and I'll let you know how I fare with it. Cheers, Joe PN me if your Boom / Classic / Transporter display has issues!

Hi there, well, you could extract a SB3 display and put it in place of a Transporter's display, they are identical. But I would consider it a big sacrifice too big to kill a working SB3 just for a display that is probably not really fresh anyway. Even if SB3s are cheap on the used market, their displays are far from beautiful in most cases. For people in the U.S. there is a great alternative in buying a brand-new front panel PCB from eBay seller *hotdogtec *here: https://www.ebay.de/itm/362191359449 It's two new displays and no soldering required. As long as the supply lasts that is the cheapest and fastest option. I am offering the MN32032A display which is needed twice for a Transporter for 78.00 EUR per piece plus shipping. It is definitely recommended to change both displays at a time, only replacing one of both will reveal heavy differences in brightness between the old and the new one, no matter how little they have been used.

Re: [slim] Analog output on SB3 no longer seems to work - suggestions?
Hi all, I would also recommend a Xilinx reset as described. On top of that, you might want to try a factory reset by holding the "+" key instead of the "1". Missing analog sound can also come from settings. Even if that's quite obvious, some people actually manage to set their SB's output volume to zero by accident and never know it. There could also be server settings that cause this. Please check these, all are on default values in case of my screenshot, but even if you find the same settings it might be worthwhile to play around with them. I remember that in some cases this brought the sound back. 37691 If you don't have a Logitech Media Server but use mysqueezebox.com instead, you can find a lot of these settings on the website, too. Most of these are not reachable through infrared commands though, so a browser needs to be involved. Bad electrolytics can cause sound output to fail but usually the device stability fails first, i.e. whenever you try to play something, the SB will crash sooner or later and reboot. So we might rather be dealing with a software issue here.

Re: [slim] I think my SliMP3 just died
Hi there, I just hooked up my SliMP3 to a lab power supply and stepped down the voltage from 5V. Guess what, below ~4.6V audio drops out but otherwise the device works (receives IR commands, display working properly, shows playing progress, etc.). So it seems the DAC is the first to quit when the input voltage gets too low whereas the rest of the device keeps working. Stepping the voltage back up leads to heavy distortions first until it recovers at ~4.65V. And it takes just 0.45A at this voltage so its power consumption is only a bit more than 2.1 Watts which I find pretty amazing. It is typical for switching power supplies that they fail to keep up the specified voltage sooner or later, depending on the load. Mostly this is due to dying filter capacitors in the secondary stage of the power supply. This does not happen all at once but is a slow but steady process so the effective voltage delivered will ramp down very slowly over time. Yours might just be in a state where the voltage is sufficient for everything except the DAC. So the PSU - once again - would by my prime suspect here. They are dirt cheap (unless you want something really well-made) so I would recommend to replace it. It's very likely this brings your SliMP3 back to full glory.

I'm considering buying another 5V/2A > power supply but a bit unsure if I should be trying something else > before jumping into that. Hi there, I would guess that trying a new power supply is a sensible first step. They are the most frequent failure point and a power outage is often the point where they no longer get to their feet because of the startup stress that they haven't had in a long time of constantly being powered. However, I cannot guarantee you that this is all you need to do. If the SB3 still fails with the new PSU, it's likely that the situation is similar inside it, i.e. capacitors needed for a clean startup and to filter ripple are no longer able to do their job and cause the system to be unstable or even unable to boot at all. Replacement of the internal SMD capacitors is my step #2 in this situation usually. I hate to give you more worries but eventually it could be CPU death which is not recoverable no matter what. All we can do is hope that it's only one or both of the other two options mentioned. Let me know if you need more detail or advice. If you are inside EU, you might consider sending me the unit to Germany for a full diagnosis (free of charge). I'm in good training regarding the replacement of SMD capacitors and testing power supplies. I could not cure CPU death but a lot of other issues.

Well, the IP never changed, neither the router's nor the DHCP address allocated for that specific Transporter. But you gave me the idea to check back with my DHCP server (which is a Windows 2012 R2 Server running my AD + DNS + DHCP services). Found two entries in there for the same Transporter! No idea how that could happen but after cleaning up both, the Transporter connected all fine, also over Wi-Fi, got the first free address which is the same it used to have before, and that's the end of the story. Some more observations: despite the fact that I ended the personal Wi-Fi hotspot on my smartphone hours ago, it would still list the SSID, along with other SSIDs, the list again contained all but mine. It needed another factory reset to actually refresh the SSID. After that, it no longer contained by personal hotspot but showed my home SSID again. Funny, seems to be some caching involved there, where it really shouldn't be. So I did not get to the point where I can determine whether the DHCP server is used or not, but the firmware seems to analyze what can be found on the net up to that point. And as the DHCP would not deliver fully valid data, that might have caused the Transporter to hang around for 30 seconds. Whatever, I would love to understand this better but that would require Logitech to disclose more than they want to. Anyway, consider this solved.

[slim] Help needed: Transporter no longer connects to Wi-Fi
Hi everyone, one of my two Transporters fails to connect to Wi-Fi since this morning, out of nowhere. The four Booms and the other Transporter in the apartment have no issues. I did Xilinx and factory resets and checked multiple Wi-Fi cards from my stock. Depending on the card, I either don't see my SSID at all, or it takes very long, or is visible immediately. In cases where I can select the SSID, I can also see the connection strength varies between 70 and 80%. I can enter the password (double-checked I entered it correctly) but it never gets beyond the subsequent step "Connecting...". It times out after 30 seconds. What would follow is usually the question whether I want DHCP or a manual IP address. It never gets there. An attempt to connect to a 2.4GHz Wi-Fi hotspot provided by my cellphone failed as well. Checked my router and it has no new restrictions or anything that might explain this. The Transporter in question connects okay via wired Ethernet, albeit with infrequent new trouble sometimes. In one of my connection attempts, the entire device was super slow and display animations were freeze-framed. In that state it did not react to any user input, too. Like the CPU is running only on a fraction of its usual speed. Another factory reset cured this for now but I'm in serious doubts now. Could be that I have one the models suffering from a dying CPU, and this could be the start of it. Anybody around who recognizes any of this? Thank you all!

Re: [slim] Squeezebox Classic (SB3) Repair Considerations
Hi there, not really, sorry. I can only offer you to have a look if you send me the unit in question (to Germany). But I cannot promise you that I will find a solution for this matter. Could be that the CPU is dying (or whatever it is that causes SB3s to die). If you are interested, please send me a PN. Cheers, Johannes PN me if your Boom / Classic / Transporter display has issues!

Re: [slim] Squeezebox Classic (SB3) Repair Considerations
Hi there, sorry, better forget about that multimeter test. A lot of people fall for this. If you measure the voltage of the unloaded PSU, you will probably find that it delivers 5V as it should. But that does not mean everything is all right. The problem is that a multimeter does not draw any current. To measure it correctly you have to apply an electronic load, and measure the current in that specific situation. A configurable battery tester such as I am demonstrating in my blog (https://joes-tech-blog.blogspot.com/2018/11/logitech-slimdevices-squeezebox-classic.html, approximately in the middle of the page) will create a defined amperage and show you what voltage is delivered under this load. It should not collapse below 4.8V at 2A. This can't be done by hooking up just a multimeter. As these power supplies are dirt cheap nowadays, I would recommend you to just buy a new one. The original PSUs are practically all dead by now after 10-12 years of constant service so this investment is probably not in vain. Be careful about the polarity though, the inside connection is positive and the outside sleeve must be negative. You can choose one for more than 2 Ampères but be sure it's constant 5V DC and no other voltage. The barrel jack is 5.5mm outside and (typically) 2.1mm inside diameter. 2.35mm might also fit, I don't know about the 5.5/2.5mm variant though. You can find tons of more info on this matter in the blog page mentioned above. Cheers, Joe PN me if your Boom / Classic / Transporter display has issues!

Re: [slim] Squeezebox Classic (SB3) Repair Considerations
These Wi-Fi boards are harder to get. At eBay, I found two offerings which are both from China. Might be problematic but I'm not sure. This the link to one of them: https://ebay.us/PdmjPl AR2413 is the chip that needs to be on the card because it's the only one the Squeezebox firmware supports. It is also important that you use the MiniPCI variant, avoid the ones for MiniPCI-e / MiniPCI-x and/or "half size". They are incompatible. There are only very few different models with AR2413 and classic MiniPCI. Compared to the PC world, MiniPCI is the analogy of PCI whereas MiniPCI-e or -x is for PCI-express so it's more modern and electrically a different design. I think that MiniPCI Wi-Fi boards may have been used in older notebooks, too. So it's rather generic, not something specifically designed for Squeezeboxes. I have only ever seen three different ones that fit. Sorry, could only find two in my collection right now: 32590 32591 A peek under the hood reveals that the PCB layout is mostly identical in both. Main differences are in the power supply sections. The blue one features a useful silk screen whereas the green one seems to be from Apple :rolleyes: 32592 A closeup of the chip in question: 32593 Which also sorts out the myth about AR2431 and AR2413. It's clearly AR2413 as we can see here. I confused this myself in my blog and just went and corrected it. Pity! But it really needs to pop the shields and look closely. I guess the stickers on the backof the cards are more helpful than what is in the front-side silk screen for finding anything similar on the market. I remember purchasing a pack of 10 of these blue cards for around 20 EUR. But that was years ago. For comparison, here is a MiniPCI-x half-length card that _won't_fit_ even if the chip used is the same: 32589 The size of these cards is only about 1/3 to 1/4 of the one we need, and the card-edge connector is totally different. If you can get a hold of the blue model, that's definitely the newer one and a better design in my opinion. For instance, it does not need that hefty voltage regulator that the old card has which spreads a lot of heat, i.e. is wasting energy. Hope this helped a bit. Please keep us informed how your story goes on.

Do you > know how the brightness remains variable even with this constant voltage > drop? Thanks for the praise! I'm happy it helped you. Actually I can't explain what good that circuitry is as the brightness control is just as good with the fix (and permanent voltage on the F2 lines) as it was without. The Noritake MN16032 display offers four brightness levels for each pixel so actually this would be sufficient already. And Logitech actually makes use of this which can be observed if you have a visual effect such as the VU meters or spectrum analyzer active. They will use some shading / brighter peak indicators in high brightness levels whereas everything is the same brightness in lower settings. The Squeezebox firmware offers "off" and five brightness settings so they use the built-in display capabilities as well as controlling the filament voltage. The latter won't work of course after the fix was applied. I think the mode in which this should be most apparent is the low brightness levels as this is when the grid voltage differential is rather low. I have taken measurements in all brightness settings, and this confirms the theory that a higher voltage differential (i.e. less voltage on F2 while F1 is constantly at +5V) causes higher brightness: Level 5: 1.418 Volts Level 4: 1.414 Volts Level 3: 1.413 Volts Level 2: 2.513 Volts Level 1: 2.511 Volts You see that the F2 voltage at lower brightness levels goes up. If the internal power supply circuitry is at fault, F2 goes up as high as +5V also. The 3-diode fix will pull the F2 voltage down by approximately 2.1V to ~2.9V. This is still not as much of a voltage differential as in the original but I did not observe any visual difference. Using fewer diodes will cause the remaining diodes to become considerably warm which will probably destroy them over time. Using more diodes will cause a higher voltage drop, thus the filament to glow which is visually disturbing and will also cause the filament to suffer. Maybe it is a combination of the diodes and what remains from the defective circuitry that keeps this working. Anyway, so far every fix worked and nobody ever complained. We will never fully understand this as long as Logitech keeps it all secret. PN me if your Boom / Classic / Transporter display has issues!

It's true, two GND pins in the 12-pin block of the Noritake VFDs have the same potential, so in this specific case it wouldn't hurt to short them together, but as a rule of thumb I would always avoid that :) PN me if your Boom / Classic / Transporter display has issues!

Re: [slim] Squeezebox Classic (SB3) Repair Considerations
Looks like a line driver defect. It's not a typical issue though, these displays are pretty solid. Anyway, in this case there is not much else you can do but replace the display entirely. I can supply displays, or even take care of the repair job, whichever you prefer. I'm based in Germany and EU-wide shipping shouldn't be much of a problem. Outside EU is a different story though...

I can accept SB3 repairs but only if liability is explicitly excluded, i.e. if I break the SB3, it's a pity but I can't replace any more SB3 CPU boards as I have only just a few SB3 units in stock and each time this defect happens, I have to gut another one. It's just so sad. So before sending your SB3 off to me, better say your goodbyes because it's possible, not to say likely, that it will not get fixed but get worse in condition. It's out of my control. Therefore, I think it doesn't make sense if you send me an SB3 where the TOSLINK LED is already dim and the power supply was ruled out as the culprit. This is the state that six of my SB3 boards are in right now. I won't find out the reason, probably nobody ever will unless Logitech discloses the technical documentation.:confused: Philippe_44 (see post above) will take care of the defective boards in attempting a CPU replacement; we are in pretty close contact about this lately. Let's see how that turns out. If good, he may be the go-to address in such cases, much rather than me. So yeah, that's the state of things. I'll update you as soon as I know more.

Re: [slim] Growing mass of failing SB3 (Classic)
Hi all, sadly, I need to give up SB3 repairs. After five SB3s failed in sequence during or after the capacitor renewal procedure (which succeeded many times before), I can no longer offer this type of service. This happened despite all measures of care like ESD protection, capacitor discharge before soldering, removing the CPU board before starting work on the capacitors, etc. So I will keep my hands off the SB3 caps, apparently there is something I don't understand about this matter, and all experience isn't helping. I can still offer the display replacement, however, with no warranty of any sort. If you send me an SB3 with a darkened shadowy display, it is not unlikely that the repair ends in a full defect. Until now, I used to extract a working CPU board from one of my own SB3s to get other people's units back working but I'm now running out of stock and motivation. This way, I spend more money on a repair than I can ever earn from it. It just doesn't make sense this way. I'm really hoping that one day somebody discovers what makes the SB3 fail. Until then, a lot of SB3s are at a dead end. Boom display and speaker repairs are still possible, of course, even though the risk of suddenly dying affects the Boom as well. It's just not happened to me yet. Hope for your understanding. Cheers, Joe PN me if your Boom / Classic / Transporter display has issues!

[slim] Growing mass of failing SB3 (Classic)
Hi all, as there is no specific forum for the Squeezebox Classic (SB3) or its predecessors for whatever reason, I'll discuss matters here. During the last weeks, I received more e-mails than ever about failing or failed SB3 models. It's like a lot of them fail simultaneously, however, not all for the same reasons. If your SB3 has issues, please check out this blog post: https://joes-tech-blog.blogspot.com/2018/11/logitech-slimdevices-squeezebox-classic.html It's still a work in progress but a lot of troubleshooting information can be found in there. In my recent experience, the power supply is failure reason #1. Which is good because owners can replace the PSU themselves and see if this fixes the issue(s). Just be careful to use one that has +5V/2A rating and a connector that fits the SB3 power supply jack properly. Failure reason #2 is more complicated to fix, it's the SMD capacitors, mainly the ones surrounding the DAC, and also in the power supply section on the opposite side of the board. This requires removing the old capacitors (Mr. Carlson's Lab has a good method, looks brutal but works best: https://youtu.be/X8N9O3a9jiM), and soldering in new ones which is tricky due to space limitations and very limited access to the soldering pads once the capacitor is where it belongs. This can't be done with cheap equipment and requires some exercise, too. I am located in *Germany* so EU-wide service is possible at reasonable shipping rates. Anything beyond EU limits is probably beyond reason regarding the shipping cost. HOWEVER: there's failure reason #3 - what I used to call -sudden death syndrome- (also described in the blog post referenced above) - and it's recently happened to me during a repair, so I need to announce that the SB3s you send to me might be beyond recovery, even though they were intact when you sent them off. This is a Damocles Sword that I can no longer account for. There is no help from Logitech about this so, to my knowledge, nobody knows what is wrong with these units and how to prevent it from happening, or how to repair the ones affected. When I receive a unit that is still capable of booting, and it dies during my repair, I'm of course responsible for restoring or replacing it. This means I will lose between 60 and 80 EUR, depending on what used working units cost nowadays, and it will leave me with a pile of garbage. As much as I love repairing these things and keeping them going, this is an investment that I cannot afford. Probably none of you will readily accept to pay this amount on top of the normal repair either. So this is just to clarify that my repair capabilities are limited, and dying SB3s are currently nothing but bad luck with nothing we can do about it. It's of course still covered by the "no fix, no fee" model, i.e. there will not be any charge for any repair work done already, and besides the return shipping there won't be any more cost for you if you want the item back. Thanks guys! Hope we can keep the Squeezebox world going, despite all obstacles! Cheers, Joe PN me if your Boom / Classic / Transporter display has issues!

Re: [slim] How Many Squeezeboxes still in use?
Any Squeezebox device is worth keeping. They are pretty reliable in comparison to other gadgets nowadays. Might not be quite so true for some of them, the Radio for instance, but in general, the construction of SBs is solid. Michael is doing a superb job in keeping the platform up and running. This should be honored much more. Hardware-wise, it's telling that a lifetime of 10 years or more is considered exceptional nowadays. My main amp is a Revox B250-S that was built in 1987, and besides a capacitor replacement there was no service ever needed for it. 32 years in permanent service, that's quite something. And I have no doubts I would still use it 30 years from now. Schematics are available, the hardware design consists mainly of standard components, and Revox keeps supplying almost any component of any device they ever brought to market. That's remarkable. I cannot think of any other manufacturer that does this. The speakers and most parts of my main stereo set are nearly the same age. Good proof that spending more money gave you better quality, at least that's what used to be true back in the day. You can now spend 1600 EUR on an iPod dock and enjoy its crappy audio from a wife-acceptable shiny 7.1 polypropylene D-class system, and these things won't even last you 5 years before they add to the garbage dump because nobody is capable of repairing the undocumented, twisted, "defective by design" components. In what aspect is that better anyway? Hi-Fi was never about fashion, still my impression is that the focus shifts towards the shell and gimmicks like app control, and away from overall quality. Something got lost along the way but it's not caused by the manufacturers entirely. It's also the consumer's responsibility to control where things are heading, and imho it's going down the drain. If your Squeezebox fails you, there are ways to repair most of the issues. I am trying to do my part in keeping the Squeezebox ecosystem ticking. Please, instead of considering to abandon Squeezebox in total, or tossing a failed device, give me a PN or create a thread in this forum. There are many people out there who will help.

I was actually hoping somebody else with more IR Blaster experience would answer. I have not used IR Blaster myself yet but would advise you to check these steps: - did IR Blaster work previously? How did it stop? Did it become more and more unreliable, or did it fail at one point? - if you are trying to set it up for the first time, did you ensure the polarity and connections on the headphone jack are correct with respect to the IR diode? - if you point your smartphone's camera (in video mode), or any video camera, towards the IR emitter diode, do you see faint purple flashes while IR commands are being sent? (please compare to a known-working IR remote control to verify your camera is picking up the infrared light) - does the headphone jack of your SB3 work properly when being used as a regular headphone output? If the left channel is missing, that would be the same pin that drives the IR diode... Hope this might help you a bit. Cheers, Joe PN me if your Boom / Classic / Transporter display has issues!

It's not just the display that goes dark? Does playback cut off in the middle of playing? Because it's a huge difference between a SB that crashes and one that fails to power its display whereas anything else is fine. The display power circuitry might have issues similar to the Boom. However, the fix that I have found for the Boom circuitry does not work properly in the Classic. I never had any Classic with this sort of failure though, so there are no advice yet.

Re: [slim] Smart people will stay with Squeezebox
Bit late maybe, sorry, but let me add that parts of the Squeezebox issues are still repairable which is also a good reason to stick around ;) I don't think this gets easier with more modern devices which are apparently built to go to the landfill after warranty expiry.

Re: [slim] My Transporter has gotten into a boot loop
Oh, sorry to read that! Hope we all can help you. How is your Transporter connected to your network? WiFi or Ethernet? To me your fault description sounds like the WiFi card might fail as it is initializing, and it's such a hard fault that it causes the CPU to reboot. WiFi cards are known for failing. Not so much in the Transporter but as this is a regular issue in the Classic and Boom units, why should the precious Transporter be spared? My approach would be this: - open the Transporter and look for obvious issues like excessive heat (IR camera is a great help here), burnt components, unlit LEDs (there are four, three of which are permanently on by default, and one flashing along with infrared commands coming in) - try to remove the Wi-Fi card that is inserted on top of the CPU board - restart the Transporter after that (with the Wi-Fi card removed and isolated). This will produce error messages and force the Transporter into Ethernet connection of course, so you should be able to connect it via Ethernet wire for this period. But if the device starts up at all, that's a really good sign - if not, do some voltage measurements to ensure that all voltages are present (I had a Transporter here for repair very recently where one of the transformers had failed!) - reseat the CPU board which requires tearing almost the whole thing down. The mainboard needs to be lifted out because the CPU board is bolted down and undoing the screw will cause a metal nut on the other side to go rogue. You don't want to keep it at that. There are tons of more tests one could do if all this does not lead anywhere. But some lab equipment is definitely required then. Depending on where you are located, I could offer you to take a look. I have a Transporter myself that I regularly use for comparison of voltages etc., and some general experience around Squeezeboxes, too. Saved three Transporters already. Inside the EU the shipping is not a big deal. Outside - a lot more precarious but still possible. Let me know what you think.

Re: [slim] Good news: ongoing production of Boom, Classic, and Transporter displays
Okay people, please PN me if you want displays. I have the "go" from Noritake Germany to ship displays wherever I want. There won't be conflicting interests with Noritake US, they apparently focus more on business customers. So it appears I am the most inexpensive source for the displays at the moment. Please check for yourselves. If it is no longer true, please feel free to announce better sources here. I'm glad to help but if there is an easier way for US people, it's all the better also for me. The pricing is currently 40 EUR for a Boom display (MN16032G or MN16032GB, depending on stock), and 45 EUR for a Classic display (MN32032A), two of which are needed for the Transporter. On top of that, there are 6.50 EUR shipping for registered DeutschePost parcel to the US. Please convert EUR to USD when the time to place your order comes to know what this actually means for your budget. The exchange rate varies a lot recently. As I do not plan to keep greater amounts in stock, please allow up to four weeks additional delivery time from Japan to me once I placed my collective order with Noritake (they don't stock a lot themselves here in Germany). So it may take up to six weeks until the display arrives at your door. But you may as well be lucky and I have enough stock to send them off right away. I'll keep everyone informed of course. I hope you all are okay with advance payment as I won't be able to afford large orders otherwise. It would also reduce the risk of orders being cancelled, leaving me with stock I don't want. Anyway, please place orders only if you are really sure you want the stuff. The pricing is not going to vary much in the future so you can calculate the final total easily. If Noritake has another price increase like they had recently, I will post new prices here.

No need to worry, they ship displays to me for instance, any quantities I want, and I'm not acting as a company, and no distributor is in the supply chain. It is as easy as can be. Noritake is particularly forthcoming in Germany. It's known that they are not as cooperative in the States though. If all else fails, you could buy from me.

[slim] Good news: ongoing production of Boom, Classic, and Transporter displays
Hi all, just for your information, Noritake is still producing new displays like MN16032GB (Boom) and MN32032A (Classic, Transporter). The MN16032G was recently replaced by the MN16032GB which is a different revision with same dimensions and pinout but slightly different electrical characteristics. I have checked and can assure 100% compatibility with the Squeezebox Boom. While the G and GB models are indistinguishable on the front side, the changes in the control logic part seem pretty fundamental. Anyway, nobody needs to worry about displays running out of production any time soon. These are closeups of the back sections where the changes are most apparent. The early model had a single chip on glass to provide the interface and drive the grid and pixel lines. The new model has two individual chips in the same place. MN16032G on top, the MN16032GB below.
