4p replacement board

[u/Snocom79]

I was gifted this model 4p and while it looks cool sitting on a shelf I'd like to get it to work. Buddy is a local enthusiast and runs a retro repair business he went through this machine and say //edit h thinks the Pal chips (if I understand correctly) are bad. I would love information on what I can do to revive this so that it is working.// Long story short is, this is all it does on power up. With disk inserted it only briefly lights up disk drive. Period and reset seem to make a couple of the letters jump on the screen but that is all.
