FM Towns Marty black screen

[Rygar]

My Marty just gives a black screen, does anyone have any idea what it could be? I already recap PSU, but after seeing with the component tester that the capacitors were already good, I gave up on the recap motherboard. I checked all the capacitors on the board and they are good. I think someone already did the recap before me.

Do they exist somewhere schematics for FM Towns Marty?

Did you measure the voltages after recaping the PSU ?

No, i have the same problem before recaping the PSU, but i will check voltages.
