Sometime this aftn, I lost my green color on the screen. If I go into test mode i have a blue cross hatch screen, white one, and orange-ish one, but no green. I played abt 30 games last nt and this am and the green was there. Where do I start?
100's are infamous for developing bad pins - ensure you don;t have a flakely pin on the wiring harness or the lead coming off the defelction board.
Reflow the header the yoke connects to on the deflection board. Reflow all components on the neck board.
also unplug and reseat the logic board edge connector...also...the one 15 pin main connector that connects the monitor to the game...unplug and reseat..also, I once lost a color on this monitor...turned out ONE of the pins in that 15 pin connector backed out a hair...so that one pin was not making contact even though conenctor in tight...look inside BOTH ends of that connector to make sure ALL pins are even and none slid back inside the housing a bit.
