All right. I did the repair, and this is what happened.
When I try to turn the Mac on, one of three things happens:
1. Nothing. Fan spins and CRT turns on but nothing else.
2. The screen alternates between two bars and three bars:
3. Garbage displayed on screen similar to two bars image, but covering right half of the screen. Makes the "drum machine" sound described in this video:
After a few seconds of this noise, it will go to 2 and behave as described.
I've looked over the board a few times and found a couple unconnected traces, but connecting them has not changed the behavior in any way. I will provide pics of the board if anyone wants to take a look, and I can take pics of specific things tomorrow if requested.
Does anyone know if Kai Robinson is on this site? I'm running out of ideas.
