Hi all,
1st post here, Apple user since well, 1984... Just started rebuilding my collection up again (Apple IIe, Apple II GS, Centris 650) and now a Classic II that I got off eBay a few weeks ago. Totally cleaned the board since there were a few caps that leaked.. Got replacements, first time at a recap attempt. Believe that I seeded the new caps correctly. Also notice that the battery must of leaked all over and the holder had been removed.
I get these lines that was also happening on first boot up. The yoke cap had fallen off, so I carefully replaced it, there were no cracks or anything on it. I have removed the logic board a few time to re-clean and double check that all was well, even re-seeded one of the ROMs and cleaned with Detox, still showing these lines and it won't boot up.
Logic Board - 820-0525-B
So, revision B of the Classic logic board.. Check. Should work in a Classic II from what I have read here on the site with others experimenting swapping out the logic board between a Classic and a Classic II and vice versa.
Missing battery & holder, have a holder on order, will this machine boot up without a battery?
Analog Board - 820-0390-03
Not sure if this is the original, would think that it is.
Here's the image that I am still getting after recapping the logic board. Fan spins, hard drive spins, floppy drive has been cleaned, no boot up disks, but I do have a SCSI2SD that I am waiting to hook up once I get the screen fixed.
So, anyone have any ideas of what could be causing this? I checked the analog board and all the caps look good. There is some slight flux residue on the back of the board I think or maybe battery leakage? If I re-solder the yoke connection to the analog board, do I need to discharge the CRT?
Any thoughts or suggestions would be greatly appreciated.
