I KNOW for a fact that the Macfaq.org covers the flyback transformer and discharging the CRT/removal of the CRT connector wire. Hopefully you saw that "High Voltage" label and have not attempted further removal. You have to discharge it to be safe, then you should be able to squeeze the clips you see through the translucent cup of the Plus through Classic models and easily pull it off. Try to get yourself a copy of Larry Pina's two books that cover the 128k-SE and SE-Classic II, they are discussed on Jagshouse.com I think. A Google search should produce some other results. It's hit or miss on those as they are out of print -- I bought mine for nothing, but there was a recent lengthy discussion about them on the list indicating that they were getting expensive again. I retract my comments about how easy the surface mount chip caps are to replace. I've done some work on a surface mount board with resistors and depending on the size of them, it can be difficult. I did not realize there were surface chip-type caps on the SEs & Classics, so you may want to leave them for now -- anybody on the list know if they are less prone to leaking than the regular kind or more prone? I don't think you need to "convert" the caps markings. I think you can just write them down, take them to an electronics store and they can translate them for you. The analogue/sweep board is the one I recommend replacing all the caps on as they are the ones dealing with the higher voltages in your compact and the MOST LIKELY to fail. The logic board caps are minor by comparison IMHO. Did you replace the battery and the date and time still don't work? Did you check for corrosion or shorting on the leads coming from the sound pins and battery?
RANT: (not directed at you) A while back a lister posted a link to another blog-type site like Jaghouse and Applefritter uses, set up for old Macs. These are much better for this kind of troubleshooting and while I do not want drive traffic from LEM and I realize these lists have there charm, ALL of the questions being asked here have been covered one way or another in the last 6 weeks. There is endless repeating of issues and solutions. Until the format of this list is updated, I suggest we all take a look at the archive section, the link found at the bottom of every posting. I just rediscovered it and realized it's pretty current and completely searchable. That keeps the troubleshooting to a minimum and directed to specific problems, while the general solutions which have been expertly discussed in some detail in the past will solve most of the basic problems and be more productive for everyone. > From: "Jan Warreyn" <[EMAIL PROTECTED]> > > "NODEraser" <[EMAIL PROTECTED]> wrote: > Is there an idiot's guide to replacing capacitors somewhere?
