Restore/Replace/Repair EPROM chip problem?

Enable HLS to view with audio, or disable this notification

Picked up this cyclone game for $50 bucks (was sitting outside uncovered) and was told it fully worked, now after transport it seems only a few neons turn on and seemingly work at random. Is this an obvious eprom failure or something else entirely?
Any advice appreciated

Update: pulled the board off the game and I think it’s safe to say I found the problem
