Hello, yesterday, in a Buzz fix party in Milan, it happen something very similar to this. One Freerunner was fixed, but the mic was busted. We had some of those at fix-party in Barcelona (first Fix party). As you are doing the fix in a hurry, you could short-circuit some of the small R's. But we didn't bork any Freerunner. LAter, on the lab, we checked the phones and they get fixed, adn works perfectly. Check the circuit diagram carefully and you see a short circuit (i'm sure).

Last week, my buzz-fixed FR became un-buzzfixed again. Someone came with a soldering iron and a steady hand to re-fix it. During that operation, he made a bridge between de 2nd and 3rd patch to the right of the 2 capacitors. He was able to get the tin out again (no problem), but it appears that this sort of thing happens very quickly...

Re: Microphone busted after buzz-fix
Thanks to everyone that answered. I will ask my friend to re-check for shorts and see what he finds. regards Tom ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Microphone busted after buzz-fix
Hello List, I have 2 freerunners and both were A5's. I have a friend that is experienced soldering and doing reworks and he performed the buzz-fix on both freerunners. However, one of those seems to have the microphone not working anymore. The other Neo was fixed correctly (despite having different resistors or whatever, the interference was reduced a lot). Any suggestions on how to diagnose it correctly? I already loaded the A7 state file (which works wonders on the other neo), tried different distros. Is there any kind of warranty (i know there's not an official one) from openmoko in case i need to ship it back to taiwan or something? Since I'm in Chile and no local distributor is available, I had to perform the fix unoficially. Thanks for the time Tom ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Give your friend schematics and the non-working phone and ask him to check circuits carefully. Most probably he left a short there that he will simply remove after finding it. -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fercer...@gmail.com ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
