I've been working on a Flight 2k and I need help. When I bought it, I took an Ultimate MPU board over and it booted right up so I bought it. Then it started resetting constantly. Since then I have replaced the Power Driver board, the rectifier board, and replaced every connector in it, and recapped the sound boards. Still getting reboot. Every now and again, it will boot a game, but on the displays, only the 3rd player shows anything and it shows
_ 0 , 0 0 (dashes represent blank digits) and shortly after it resets.
I've tried 3 different MPUs and 3 different power supplies. Depending what power driver board is in, I'm either getting 4.9vdc or up to 5.2vdc on the MPU board. I've tried disconnecting sound boards and light boards with no changes in behavior.
