I just picked up an x-men and got it working(bad power supply). The monitor is not showing any green. How do i tell if its a chassis issue or a tube problem. plz help if you can. thanks so much. It looks like a 25 inch monitor.
it could be your header pins on the chassis, it could be a transistor in the color circuit, it could be your tube, it could be your connection in the jamma harness, it could be the video connector, it could be that you need a cap kit, it could be the chassis is a POS, it could be several other things.
the K7000 series is a very easy chassis to work with.
i would start by reflowing the video input pins on the chassis.
then re-flow the 3 color transistors on the neck.
and check the video input connector to make sure the wires are in there and making a good connection.
wile you have it out my recommendation is to do a complete cap kit and fly on it.
