“What’s the Diagnosis Doc?”
Last week, Centipede decided to jump line in the repair queue with a monitor problem.
Monitor dark, game was playing blind and no neck glow. It had been playing fine the day before and hasn’t shown any warm-up quirks leading up to the failure.
My gut reaction was - flyback.
Before ordering parts, I consulted this handy troubleshooting workflow chart:
(first google result for g07 troubleshooting chart)
The fuse at 901 was indeed blown and you can see a slight crack in the flyback. I’m surprised it wasn’t arcing. If it was a Hantarex it would have arc’d… :)
I ordered parts from https://www.arcadepartsandrepair.com/ (the first time I’ve used this particular site) Prices were average, shipping was fast and the order was correct.
Not a fan of axial-lead fuses, so I added board-mount fuse holders when I replaced the fuse.
The new flyback proudly boasts its Chinese origin. Hopefully it’ll hold up? The transformer adjacent to it at T-503 looks pretty crusty but works and those aren’t made anymore, so I’m leaving it.
Time to Test it Out
Quick test showed neck glow was back. I made a few small adjustments and we were back in business.
I let the game “burn-in test” for a couple of hours and so far-so good. Fingers crossed it stays working so I can move on to other regularly scheduled projects in progress!
