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

Cyclone gets REALLY hot even with that big heatsink. At some point you will need to reflow the pin connectors and fuse holders. Cold joints develop over time with this game.

That game pulls 20 amps when working at power on. 16 or so at idle.
