Power issue service bulletin:

Also, if you did a ROM update, have to make sure you use 120ns or faster EPROMs:

Also make sure your display ROM major version matches your CPU ROM version:

Is the game playable? Is the only thing bad the display? If so, that looks like a bad display RAM to me.

Connectors.

If you have a broken pin on one of the ROMs, it could cause your display to blank out or other strange behavior as well. Verifying the ROMs for both contents and integrity of the pins as well as correct speed is an easy first step. And getting the power kit to install a good second.

And these service bulletins are all gone now thanks to Stern's newly redesigned web site...

The ROMs look like they were reprogrammed and they are of the correct type for that board. The -12 indicates they are 120ns ROMs. Unless you have the ability to easily check them or replace them I would assume they are ok as the pins and sockets look ok to me (from what I can see.)

Your voltage is low. Definitely need the voltage kit. Marco used to have stock but is currently out.

If that doesn't fix it I'd go with the RAM.
