The voltage output has been rechecked and I now have proper voltages. I pulled up all of the caps in the Power Supply and replaced them. Two of them actually had leads fall out, so I believe those were the bad ones. The computer gives a startup bong. From there, the computer's top half of the screen appeared, and so I replaced Q1 and the resistors R2,R3 which had burned up (according to Dead Mac Scrolls). I also went ahead and replaced: Q2, Q5, and CR15 according to two other sections. Now the machine gives the bong, and on the screen is a bunch of lines, which are spaced just a bit, but get closer together and then finally a bright white line in the center of the screen. What should I check/replace or adjust now? I can't believe the thing actually is working this well!! Hopefully I can get it fully working again!
