I am not that great with video game repair, but i know a little bit about it. I got a casino video poker V2336 i think it is. none of the lights work. lol. the tower light is dead, and the button lights are dead. everything else works. the bulbs are powered from a 6.3v AC supply and each bulb gets pulled down to ground via TRIACs on the control board. 6.3VAC is at all the lamps, and i changed the triacs. no bad fuses. i guess the actual logic ICs on the main board is bad. heck i dunno.

A few years ago I found a Tron upright video game next to a dumpster for a restaurant that was being remodeled, it had been rained on for days.
Dried it out, replaced the lower 12" of the case (which had been ruined by the rain) with black melamine board and the game came on and worked perfect. It's living in my friend's game room. Amazing how hardy the early circuits were. Mbates, I once repaired an early digital pinball game with a lot of failed lights. Turns out that a lot of the triacs were toast. When I changed them I found that there was also a driver transistor between the logic circuits and the triacs that were blown (from long term excessive heat). After changing the driver transistors I got all the lights to work. Perhaps you have the same situation? Rob
