Help,
Turned on tron with a white screen ,no sound ,looked at the main board and the led is not on..any help on this.Is the the main board bad?? I checked the monitor and its ok.

thanks for the help
 
check your voltages. Odds are one of them is off and that is keeping the board from booting. I don't believe the led on the board is supposed to be on.

If you are using the original linear power board it's most likely your problem.
If you find the linear board is good check the Z80 on the Super CPU board
 
Also, check that the video output is plugged into the MIDDLE board. It will plug right into the SSIO with the rest of the cables, which I think gives some type of white screen.
