Hi, my monitor MS8-29 started exhibiting horizontal bending issues on turning on the machine. It stays like this for a good 5-10 minutes before it becomes normal again. What could be causing this? This started happening after my machines were moved from my house to a venue. View...

I noticed one of my MS8-28 monitors is producing thicker scan lines than my other one. How can I dial down the amount of scan lines showing up on the monitor? Or is it dependent on the tube? I believe the chassis are the same.

I am in search of a Naomi Net Dimm.

Anyone have one for sale?

I ordered this jamma extractor from Axun https://www.axunworks.com/product-p583683.html and it is working. However, it seems to cause some video degradations when it's plugged in. I thought it would just be a passthrough but it's somehow making the video darker. There's only 1 gain knob on...

Small project I just did getting the Chinese JVS I/O working. I was running initially with just a Sega I/O but the colors on my machine looked washed out. I tried both Rev A and Rev B Sega I/O and both had the same issue. I didn't see the washed out colors with the Chinese I/O however but it was...

I managed to kill my 400-5198-01 PSU by blowing the IC3 transistor and D9 diode. The AC power passthrough seems to be working still on it. Here are my questions, 1) Is it worth it for me to try to find replacements for IC3 and D9 and try to replace them to fix it 2) I've remove the broken...

I just got my Naomi2 setup on my Astro City cabs and I'm noticing that the color is kind of washed out and the whole image isn't as bright as I'd expect it to be. There's also some kind of weird sepia tone to the colors. It's running on 15khz mode and I am splitting the VGA signal via a cable so...

The back of my trinitron has a composite and an s-video input. At one point, the composite input seemed to stop working all of the sudden but the s-video was still working. Today, I went and tried the s-video input and I got no picture but then tried the composite video and the composite was...

My vertical position image on my nanao chassis is not able to be adjusted. I can't move the image up or down. It's not the controller either because I tried another one that I know works and that one doesn't work either. It looks like it wants to move and shifts slightly but never really moves...

I have 1 CRT monitor in my Astro city that starts out stretched a bit wide when I first turn it on, after a few minutes, it goes back to the correct aspect ratio. I don't know why it's doing this. I'm afraid to poke around and making it worse. I've tweaked with the H and V syncs and they didn't...

My monitor started flickering all of the sudden. It's has some horizontal lines flicking in and out of the image. It happens now and then and is not constant. What could be the issue? I'll try to see if I can get a video of it.

I finally finished setting up my 2 Astro City cabs for head to head. I made a video showcasing some of the process. Enjoy! View: https://youtu.be/HQUdaZ4ELek

Hi all of the sudden, my A board is failing to render the sprites correctly and the characters are all transparent now. It was working fine before. The audio out is also only coming through right channel through RCA ports. Any ideas? I tried the resetting of the audio by turning volume all the...

Help, I recapped my Astro city psu and plugged it back in again. The machine turned on okay for 5 minutes and then the monitor shut off. It’s not coming back on again. My psu is 400-5261Y. I tested the machine with a second psu I know that works fine and the monitor is not coming on so I...

Hi, I just got an Astro City machine and one of the stablizers in the bottom is missing. I just need a screw and a washer or some sort to screw into there to make a new one but I need to know the size that I need to buy. Does anyone know how I can find out what size I need? Or maybe you have a...

My audio from the red and yellow stereo jack stopped sending out signals all of the sudden. Everything else seems to work. The game is working fine but I get no audio out of the audio jacks. Anyone know why that could be and how I can go about fixing it?

Hi I need to configure my monitor and it just seems blurry. The verticals lines seem sharp but the horizontal lines are all blurred. Any help on how to configure this? I tried playing with the convergence rings and I can’t seem to fix the blurriness.

I recently just recapped my Nanao 2930 in my Blast City. I believe I plugged all the cables back correctly but it doesn't seem to be powering on at all. Before I go back in and checking all the soldering of the capacitors, is there anything else I should be checking to see why it's not powering...

My composite output from the back of my CRT stopped functioning all of the sudden. The front ones still work. What would be the most likely reason for this? Is there an easy way for me to fix it?
