This board was working fine. Bench tested and in a Trident game. Flicker and 7 flashes.
I pulled the board to replace the RAM for NVRAM. Bench tested before I put the board back into the game. Now I get a flash - pause - then 6 flashes. (see video):
(I have 24 volts to TP3 to get the 7th flash.)
It seems correct but what happened to the flicker?
