Tempest monitor display only purple with several extra lines....game play is 100% OK, just the display is all squigley.
Updates include:
*ArcadeCup work done to monitor boards (with LV2000 installed)
*New "big cap" on power supply
*Main PCB, Aux PCB, and power regulator PCB boards sent for repair work to two reputable repair facilities. (also tested on another Tempest game and the boards all work 100%)
*Replaced full wire harness
*Monitor transistors replaced (all 6)
*Reseated all wire harness connectors
