Hi Guys,
The short version of my issue is that I have sound, but no image, using an MV-1C on my Type II cab.
To complicate matters, my MV-1F, CPS2, and Cave (Deathsmiles) PCBs all work great.
Before you say that perhaps I have a bad MV-1C, I have now tried 3 different MV-1C motherboards, all with the same result. In fact, one of them in brand new.
History: To give some history, about 5 years ago I bought my cab with a Wells-Gardner D9400 tri-sync display.
In my early days as a cab owner, I once plugged in a game with extremely loud volume. In my hurry to turn the volume down, I incorrectly turn the voltage pot. Eventually breaking the pot before I realized that I was not adjusting volume. Lesson learned, I dug out my multimeter and replaced the PSU (with the same model PSU that came with it).
Ever since that event, I cannot get an MV-1C to work. The marquee LCD will display an image from an MV-1C (or any PCB), but to simplify troubleshooting, I have removed the marquee LCD from the harness and the result is the same: no image on the CRT.
I have verified my PSU voltages, checked the pins on the Jamma harness, checked the pins to the monitor input. I'm stumped!
If it helps, the D9400 monitor will display "No Image" if there is no source input. Instead, I am just getting a black screen with nothing on it.
