I picked up a time warp this past week and it was dead; the machine wouldn't boot even to the point of no running feature lights and two flashes on the mpu then nothing. Well, I checked all connections, unplugging and replugging and I get feature lights, but they stay on and the driver board lamp resistors get insanely hot. It now boots up with a single led flash but then stays on. Also of note, the diplays all read as such (8 thats two eights with nothing lit before in the middle. The game does not go into attract mode fully as all lamps do not strobe, but stay solid and constantly lit up. I obviously tested power supply output 5v, 100v, ..... thinking I'm not getting the pulse for the lamps to the driver board from the power supply, among replacing and reflowing cold solder at the least on the 40 pin. My question is, what pieces on the power board are entailed and may need replaced in the lamp 5v pulse circuit? Thanks in advance!

The mpu is flashing and when I turn it off and on multiple times with the coin door open it does the one flash then off. With these old pins, caps and reflow of connectors is mandatory 20 year maintenance. Just need to know the 5v pulse circuit pieces in order to replace them.

Well, CPU is working the lights are all on, must be the 40 pin needs replaced. I'll do that. Thank you!

Not the mpu, I put a rottendog in it and all it did was put a few more numbers on the player one display. I'm going to have to rule out both Mpu and drive. I did the steps in order on the rottendog how to sheet included with the board and everything checked out good. Hooked everything up and got no real improvement. Purchased a new power supply and I'll see with the rotten dog Mpu driver combo and power supply if it's a short on the playfield or not.
