Board flex and socket/seat issues is usually the culprit. These things run extremely tempermental even when they "work"...

After a few years, i have now a similiar issue.
As you can See on the Monitor the Video SRAM is Not reseted by CPU. I can use the Keyboard reset but it doesnt reset the Video RAM.
No Progress in it ?

I have also noticed a very asymmetric real time clock on the CPU - 4x times longer high than low.
Yeah the tube or something in my old CRT would make the screen go pink with white lines across the picture. A good slap would always reset it but the intervals got worse. Initially it was once every few days, then it got to needing a slap every 15 or so minutes.
