Hi all! Been working on a PSU for my Exceleena 2 cab. After recapping I now get a sort of quiet high pitched noise coming from the PSU which also leaves some small ripples in the picture. This has occurred when connecting my Cadash board and other non-Cps2 boards. When I connect any of my CPS2...

Greetings! Sorry for the confusing title, not sure how to describe what I’m seeing exactly. I’ve attached a small gif that shows what’s happening when performing the jvs test.

Hey all, I was excited by the idea that this was a 1st generation big blue, but turns out after much cleaning, it’s a dang Leland Pig Out :( Not sure what to do now. This pic shows how someone put a AVP in their Pig Out, should I do something similar? I noticed the weird angles at the...

Greetings Everyone! So, I’ve been going through it with this AWSD... Here’s a brief history... Swapped tubes and using a Wei-Ya universal chassis and using a 100v step down transformer.. Started to See waves in the screen. Went to turn off machine and got shocked. Grounded the green earth...

Greetings Everyone! Didn’t know if I should post here or not, but came here due to the eprom burning title. If I need to post elsewhere, please let me know and I’ll be happy to do so! If this does happen to be the right place, I have a Simpsons arcade PCB that is missing the eprom at 6E. If...

Greetings! I've been playing the Atomiswave a lot and finally noticed a little wave that starts at the bottom and goes about 1/3 up the screen and repeats. I figured it was a power issue, so I looked to make sure I had everything hooked up correctly to my Powerbright VC500J step down converter...

Greetings! If anyone has this tube in there AWSD, would you be so kind as to snap a couple of pictures of the convergence rings on your yoke? Got my first candy cab and trying to get it up and running. When I removed the dreaded M3129D chassis I noticed that the convergence rings on the yoke...

Greetings!! Got my first candy cab!!! But it’s having some problems.. Powers on with the step down but monitor flashes once, then you just hear a clicking noise like the monitor is trying to fire up. Any help would be greatly appreciated!

Greetings! I’m attempting a monitor swap for my Neo Geo big red. I have an rca tube A63ADT10X05, which is indicated as being a great match for a WG 25” K7000 chassis, which I have hooked up. I hooked up everything and all I’m getting is what is in the picture below, a small blob consisting of...

Greetings All! So, I keep getting a bit over my head with this, but I figure more practice only helps. So, I picked up a final fight board that has a serious graphics problem (I'll post a pic here soon). Upon booting up, the screen is literally covered in a wall of dollar signs ($$$$$$$)...

Greetings Everyone! I have a Golden Axe pcb that performs great besides "voice" sound effects. Everything from music to general sound effects work, but no voice. I tried replacing the mpr-12384-a11 rom, but still no voice. Not sure if I need to go as far as replacing the Zilog Z80 or not...
