I've had a similar issue on a different chassis and it ended up being a ceramic cap failed causing the blanking signal at the end of a horizontal sweep cycle running too long and causing the start of the next cycle to also blank. U101 is responsible for sync processing and generating the...

You don't need a step down from 120v to 100v. Adjust the B+ to the correct value and it'll be fine.

Nice machines! The UK ones seem very close to the Japanese ones and I'd happily take one if it was available. Besides the deluxe which was Japan-built, we mostly got these wooden Sega USA abominations here. Mostly wood build, flimsy side plastic and the seat backs are always cracked because Sega...

It's already dumped and in MAME. It's a gambling game, so I wouldn't guess it has much if any value. https://adb.arcadeitalia.net/dettaglio_mame.php?game_name=am_mg3a&lang=en https://github.com/mamedev/mame/blob/master/src/mame/misc/amaticmg.cpp

I've repaired 15 GDROM drives this year and had 100% success rate so I figured I would post my notes somewhere. To swap the laser assembly for testing, instead of trying to plug the cable in while it's mounted to both rails I have found it easiest to remove the white plastic stopper holding the...

A couple little repairs today. Trying to clear out the piles... WG K7500 Symptom: Odd contrast behavior (colors clip/go at different rates as contrast pot is turned) Neck board C512 ceramic found out of spec. Replaced to fix. Sanwa 29E31S Symptom: No width/pincushion adjustment Flyback...

Here's where it's at now, about 98% done. Thank you again to @djsheep for helping get the marquee from Australia. It cost an arm and a leg to ship, but it was worth it. We never got these in the US so they're unicorns when they show up--getting this machine is my first time even seeing one in...

Can anyone measure the height of the Capcom logos extruded out of the side plastic covers of the control panel? Someone sanded mine off and painted over them, so I plan to 3d print some with the correct height, then epoxy them on and paint over the whole thing.

Hold TEST on boot or maybe flip a DIP switch to bypass the automatic tests and immediately go to menu of individual tests. It takes a long time to do the entire suite of tests when sometimes I just want to do one specific test. Show OK/FAIL on each pass of the RAM tests. If it fails on pass 1...

They're just spacers, you can remove them.

Those look physically too large to fit. My friend uses these Visatron 4" shielded speakers and they sound better than stock. https://www.parts-express.com/Visaton-R10SC-4-Full-Range-Speaker-8-Ohm-292-597?quantity=1

Bump. Been almost a year since I ordered from Atomic City and he has still not shipped. He does still reply to my messages after a few weeks, and he sent me a picture of the panel done, but still no ship. So I'm still looking for one. Would also take a T-13 panel since the cabinet can use those...

Sharp Image (Kortek) SI-727-DS Symptom: Bad horizontal linearity but only when set to medium res Spent way too long chasing this one. Ended up being either C417 or C418 failing under load despite testing good even when tested at 100khz using a DE-5000. I knew it had to be a poly cap so when I...

27" or smaller is usually easy enough solo. Never had a problem personally. 32" and bigger, awkward cabinets, or frameless monitors; why not just.... ask someone for help?

IIRC you will not get full width when using the MS9 chassis with the MS8-29 yoke. Have them send you the correct yoke. BTW, the larger yoke connector is called TJC1, the smaller pitch one is called TJC2. You can pick them up for massively cheaper on Aliexpress. They are the same exact ones...
