Picked up a Pump it Up cabinet a while ago, and finally got a PC running inside it. The pc works fine, but the monitor is doing a weird zooming thing. It reminds me if someone sat and kept hitting zoom on the screen over and over really fast, and it just keeps looping over and over from small to larger; about 2-3 inches (in zoom)

I took some pics with my phone of the monitor boards, but I have no idea what type of monitor this is. They're not the best, but hopefully someone might know what's up. The only thing I saw on it was that it had a label with 'Samsung', but couldn't see any specific model.

Also, I'm not sure if this is more of a pc problem as well. I'm using onboard video currently, but will be getting a dedicated video card soon. Also, I tried adjusting the 50/60 on the flyback (the lowest pot, in the pic it's the white one), and the picture eventually stopped doing the zoom issue but the screen was too bright and washed out. After a little while like this, the image altogether just cut out. Lowering the 50/60 pot and restarting the machine brought the image back, but the zoom problem continued.

So don't know if this is more of a pc issue, or something like the flyback going.

Looks like a Kortek KT-2914F, but without you pulling it and taking higher quality pics, i can't be 100% positive.

Still, if this is VGA, and you have a PC in it, try hooking up a computer monitor to the video output of the PC and see if it does the same thing. If so, then it is a PC problem. If not, then it is a monitor problem. If a monitor problem, start with replacing all the electrolytic caps and looking it over for cold solder joints. Then see how it looks...
