    What would cause pincushion and hor.width VR (pots) to not work?

    Hey! Just finished recapping my Weiya 2628HR. First time doing this so really happy its all working. I also changed the hor.width cap to narrow the image a bit which worked well. Need help troubleshooting the next issue: there are 9 adjustment pots (on a separate board). 7 of them work fine...

    Just got my first PCBs! .. and desperately need some experienced advice!

    Hey guys, great news! three out of three patients are working 100% now! Fantasia 2 was having video ground issues. I connected jamma pins 1/2/A/B to video ground and all video issues were solved WR2 was totally my fault... I was giving 5.15v while it wanted exactly 5v. With 5v all the weirdness...

    Makes sense! Thanks! I was aware of the way it works with two players and two cabs ("twin racing"!) but didn't expect that kind of shorting behaviour. Live and learn :) Thank you

    Hey guys - great news! Pinball action is back in action. Seems like someone had worked on the sound section previously, replacing the usual volume pot with that black square I showed in the photo. Rotated the inside and volume is back :) Happy days! One down, two to go!

    Why did nobody warn me?

    Thanks for the welcomes guys! Great community :) Today's fun discovery was that my world rally 2 PCB has what's called a "suicide battery". I initially thought the batt was just for high scores but a little reading later I realise that if this gets removed or runs out it is good bye WR2. Its...

    Just got my first PCBs! .. and desperately need some experienced advice!

    Hey Nem - that's a good observation... yes, it is. I'll show my noobness by asking this: I've calibrated my CRT for my MVS (using the MVS motherboard pattern) and it is perfect (whites are white etc). Could it be that I need to re-calibrate the screen for PCBs (or even, for each PCB?)

    Hi guys! Having just written this I see just how long it is! Apologies in advance! New to arcade PCBs and in desperate need of some experienced help :) Got a dozen or so MVS games and had no issues whatsoever. I recently bought 3 PCBs and the problems just pile up. It may be I'm missing...

    Why did nobody warn me?

    Hi everyone! Why oh why did nobody warn me... one day I'm happily minding my business and the next day I find myself addicted to a new hobby which seems to go incredibly deep. Every little thing I look into I realise there's a whole new world to discover! CRT adjusting CRT safety (scary!)...
