The sound & game play is 100% working, just no monitor/ picture.
Things I've observed:
-Monitor neck has the orange glow
-All fuses at power supply check OK
-Both LEDs on the LV2000 light up
-Spot killer LED doesn't light up at all--even when 1st powering up the Tempest
(this LED should at least -flash/ flicker for a sec or two upon start-up, right?)
-F100 fuse location voltage reading: 25.00 volts
-F101 fuse location voltage reading: 25.00 volts
-No voltage readings at F600 & F700 fuse positions
-Voltage readings on the two black wires within the main wire harness for monitor are 25.20 volts
-Game will go into Test Mode, but still no picture/ video
-LED on both the main PCB & AUX boards are on
Updates/ fixes I've done over the last 2 years (or less)
*ArcadeCup work done to all 3 monitor boards (with LV2000 installed)
*New "big Cap" on power supply (Bob Roberts)
*Main PCB, Aux PCB, and power regulator PCB boards sent for repair work to two reputable repair facilities. (Electron Forge & (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 and wires within the connectors several times
Any suggestions on where to look?
