Looking good. I just recently stared mine, and replaced a bunch of the stock stuff. Let me know if there is anything you need.

Wowzer, that appears to be an adjustment issue, either with the way the flipper was set or where the ball guide is sitting. It's something to be aware of when reinstalling, check your spacing and adjust flipper accordingly.

Also kudos for taking the time to regrain. I've been on the fence about it, but it may be a nice break from the PF stuff. The flaps are awesome. I've heard these work great too, but only go up to 400g: https://www.harborfreight.com/4-in-400-grit-abrasive-ball-61183.html

Great progress, everything is looking awesome so far!

Bumpers are pretty much the worst of it. There is nothing more miserable. You're doing great and they look sick!

Check your ribbon cables, reseat and check continuity. 99.9% likely it's a cable issue.

Do you have another display or ribbon cable on hand so you can rule the display or cables out?

Wow, that looks like my old HS CPU. It should be easy enough to test the continuity of those traces to make sure they are all in tact.

I've got a great board repair guy out here. He's setup with all of the Williams test rigs. If you want his name I would be happy to pass it along.

Deep breath, it's rare that these things can't be fixed.

My boss has a minty Gorgar, I sent his boards out to be rebuilt, got them in and seated the ribbon cable incorrectly, boomsauce down the line. Sent them back out to my board guy and a few swapped parts and they were as good as new.

It sucks, but it happens and luckily you have plenty of resources available to you.

Very nice. What did it end up being?
