I recently bought an old Golden Tee Live 2009 cabinet with the intention of turning it into a MAME machine. It had a CRT in it which I believe to be a Wells Gardner D9200. Googling the numbers at the bottom of the chasis brings up several posts about D9200s and my monitor looks pretty much identical to the one seen in this youtube video ().
I have two issues that I have been unable to figure out after searching. I'm hoping to get some assistance with them. I am very new to this and don't know much about CRT repair or troubleshooting, but I am somewhat competent with basic electronic skills (soldering, metering, etc) and maybe above average with computer skills, just to give you a baseline.
First issue, the picture is tilted pretty severely to the left (i.e. right side is higher than the left side). The monitor is mounted squarely, just the picture is off. The neckboard appears to be on straight. I have tried turning a couple of the pots on the board, but nothing changes. I also tried to use the attached menu board (four momentary buttons), but can't get any sort of adjustment menu to come onscreen. The "SELECT" button seems to degauss, but none of the others do anything.
Second issue, I can't seem to get a working picture from my computer. I am running Windows 10 with a GeForce GT710 GPU. I have tried setting the resolution to 800x600 and 640x480 (both of which I think the monitor supports) but I only get a brief BIOS bootscreen and then the CRT says "OUT OF RANGE". I'm not sure if I need something like Soft15kHz or an EDID dongle?? I'm hoping someone can give me some troubleshooting steps to try.
Thanks in advance for your help. If I left out any info that is needed, please let me know.
