Recently picked up a Neo Geo MVS 2 slot cabinet. When powered on the monitor presents with two issues. First, the right half of the screen is lighter than the left. Second, the screen has a wavy effect that travels from the bottom of the screen to the top (reminds me of heat rising off a road). It doesn't effect the color other that the fact it seems to be linked to the right half of the screen being lighter. Gameplay is possible and after a while you don't notice the screen issues, however, I want to remedy the problem so that it doesn't worsen in the future.
Having worked on this machine prior to adding to my collection I do know that this problem started several months ago. The first time it was noticed was immediatley after installing a Metal Slug cart. Not sure if that was the culprit or if it was just a coincidence. I have disconnected and re-connected all the connections to the monitor and even tried disconnecting the monitor ground since it is mounted to the chasis (has been know to cause screen distortion in Q*bert machines). So far no luck. Any advise or guidance would be greatly appreciated.
