Ok. I have been through the Sticky and associated threads and I can't find anything that can lead me to a repair. I have done a cap kit and checked all the appropriate diodes and resistors and they all check good.
The monitor starts off full screen, but has a squished top area as if the 50-60hz pot need to be adjusted but I can't make it go away. Here's is how it looks upon power up...
But within a few minutes, it starts doing this...
I have checked for cracked pots too but they are all good. No matter what I do, I can not get the screen to fill without having the top being messed up, regardless of the fact that after a few minutes, it goes into partial collapse. I have checked D13 and R80. Both good.
