having trouble with one of the arcade cabinets. It's a 1 slot MVS that has been refurbished lately. The symptons are the following:
1. Test screen is perfect (see image)
2. When game starts there are vertical (and horizontal) lines across the screen (this seems to vary between reboots/inserting removing cart)(see video)
The following has been tried already:
1. game(s) tested with another MVS -> games are ok
2. Cleaned the cart slot throughout -> no help
3. Bought a new mobo (that has been tested) -> same problem -> mobos are ok
4. Measured all the voltages -> all within specs -> psu is ok
I'm totally loosing it. What an earth can be wrong anymore? The Jamma harness?
All help highly appreciated
