Hi All,
I have been fearing this day for a few years now, I killed Superman and don't know how to revive him.
I was having a few issues with the machine so I decided to reseat all the connectors on the PCBs. The machine was turned OFF but was still plugged in and the power was on at the wall. As I was reseating the power connector on the lower left of the processor board, it has come into contact with the foil cardboard behind the board which resulted in a spark and pop. I located two ICs at H3 and H4 that I thought were the ICs that touched the cardboard. They tested bad and I have since replaced them. I tried the machine again and all I have is GI lights and a zero in each display. LEDs 1, 2, 3 and 4 are NOT lit on the processor board.
Does anyone have any idea where or what else I should be testing further up the line that has obviously been fried please?
Last option, does anyone know of a working processor board for sale if I need to go down that track?
Thanks in advance.
