I have a Hantarex MT3000 9" monochrome monitor from a Merit dart machine. It was working until I moved the game to another location. Now nothing.
The input is 12vdc, I can hear a slight electronic squeal from it and that is about it. No heater, nada. Measuring the voltage at R28 (test point) I get just under 5vdc and it should be ~10.8vdc. Something has to be shorted/shorting to drag down the voltage, but I am scratching my head more and more trying to find what can be the issue. The schematics I found online are "fuzzy" at best due to the scan resolution (Mike's has them on their site) so it is hard to read the location/type of component.
Anyone familiar with these or have worked on them that can lead me in a direction? Trying to get other ideas that maybe something will spark a path to a solution... or the trash
