On Monday, I tried out my “repaired” SF2: CE PCB. Sadly, it still doesn’t appear to work. I can’t hear any audio. I tried cranking up the potentiometer for the volume, but it had no effect.
I also tried out the SF2: Hyper Fighting board I got over the weekend. That does work. I can hear audio and can enter the game and use the joystick and buttons just fine. However, the monitor is still showing me a bright green screen. 🙁
I’ve been doing a lot of research online about arcade monitor repair. There is a lot of good info out there, especially on YouTube where people show you how to disassemble the monitor chassis so that you can fix it.
Visually inspecting the monitor chassis (i.e. the PCB for the monitor), I don’t see anything jumping out at me. I’ve determined that this is a Wells Gardener K7000 display. The PCB looks okay. No indication of leaky caps. No leakage on the boards or bloated caps. The flyback appears to have slight cracks in it, but nothing major. In operation, I don’t see any arcing around it, so that seems okay. However, the entire thing is super dusty. Here are some pictures of it.
Look at that dust:

I plan on repairing this soon, so if you have thoughts on what might be wrong, leave me a message below! I’ll post updates on this blog as I progress.
