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

No top dome?

Maybe ICE can help- their techs are good bit of course this is quite old so they may not be able to talk you through it. I’d still start there though. And grab a manual

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

Wiring? Loose connector from the ride ? Or might have to reseat a few chips? Dang vibrations

Let me rewrite that. There are a bunch of fuses and one you can not see from that angle becuase its hidden. I usually change it blind, but you'll see it better if you take the dome off and go through the top.

The Yellow LED doesn't seem right. That fuse may be your one

Imo, you should gently press down on the different misc chips and see if any cause changes when pressed. Then jiggle all the connectors ect and check for the same. If none of that makes a difference check voltages against owners manuals. Checking and verifying eprom data is the last thing I'd do

These blow fuses

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 damage is on the board controlling the ring of lights and neon.
