I've had this machine in my home for a while and it hasn't been moved in over a year. Low plays...good condition but the monitor just goes black one day when I turned it on. It plays blind but nothing on the screen.

I plugged in another jamma board and both the picture and sound are fine with this other board as a source. Seeing its a board issue, I re-seated all the socketed chips but they seem to be just the game roms.

What on this PCB board should I look for that would cause it to lose picture randomly?
 
Check your voltages on your power supply. Sounds like it may be weak. It may run other pcb's but Rev x needs a bit more amperage that a lot of other games. I've owner a few Rev X'S and they have always needed new power supplies.

All voltages are good. I put in a new power pro supply for good measure but nothing changed.

I am getting all LEDs to light up as they should on all boards. The game still plays blind.

Is this a common failure on Rev X? Should I look for a new logic board??
 
New battery as well and the monitor is rebuilt. Any other suggestions or does someone have a logic board they could sell me?
