Hi All -

I have a JD that I recently picked up that won't complete its' boot sequence. I have uploaded a video below. The battery holder was coroded, so I thought that if I removed it and neutralized the area (there didn't seem to be any real 'leakage') it would resolve the issue. Unfortunately, not. I'm not super familiar with what all of the LED indicators on the boards mean, but maybe someone can help point me in the right direction. It gets to where it makes the 'dong' sound in the sequence, but doesn't progress to power on the GI/inserts, DMD, etc.

Did you try re-seating the cable connectors?

Can you take some hi res photos of the area below the battery holder? The chips directly below that area may be eaten up.

Finally got around to taking pictures of the CPU. Took a picture of the socketed chip below the battery holder. What I didn't anticipate was the jumpers on the underside of the board. Anything look out of the ordinary which would cause the issue?

Yes, that's a lot of corrosion/battery damage, especially around U20. It seems you have quite a few other WPC games with the same cpu, swap on in and test the game if it boots then you know the CPU is the culprit. If you don't have the skills to swap in new chips and components, I don't think it's a good idea to send it out for repair, at a minimum you're looking at 100 bucks for repair and 30 bucks for shipping, and it's still looks like crap after the repair. You might as well buy a used one off of ebay, (or even a new one) and swap over the ASIC chip and rom.

Plug only the J210 to the MPU to see if it will boot. The corrosion at the bottom of the board damaged the switch matrix, but it should not keep it from booting up.
