I have a Gravitar with amplipone monitor that is playing blind. Game starts and you can play but not see. There is neck glow on the monitor, and the red led is on on both mpu board and deflection board. I e read several things pertaining to the graphics chip needing replaced? Have also read on a spot killer problem. I'm green so I can only do so much. Could use help if it's something simple or looking for so. Ive reseated all chips and cleaned legs, rep logged all plugs, checked fuses.
Done really good to repair things for me.
