Tron/MCR Power Supply Issues, White Screen of Death
Got a little surprise in the mail today, some shiny new Tron ribbon cables from Bob Roberts. I figured getting these was a good step towards getting the game up and running, as it was dead when I got it.
I've really only done minimal work on the machine so far, IE testing for voltages and replacing the power cord, the old one was in really bad shape.
Before installing my ribbon cables, everything was getting power except the gameboard as it was not connected (obviously). After installing my ribbon cables and re-connecting the game board, I am still getting a white screen with a nice loud hum from the speakers. Still no power to the game board. I re-installed the ribbon cables twice, double checked my connections, and still get the same result.
I've tested my power supply according to an MCRII manual found on the forums, and am getting in the neighborhood of what should be the correct output voltages. With this in mind and all my connections hooked up I am still confused as to why the game board is not getting any power.
Maybe it's time to get a switcher/and MCR adapter? I didn't want to attempt Bob's rebuild kit as I figured I might mangle up the PS more on accident.
If anyone has a pic of their Tron PCB hooked up that would be great so I can verify all my connections are correct, I am pretty sure they are though.
Thanks for any help and in the meantime I'll be out in the garage...
