Ok. I get to my friend's house to check out his MC.
On the edge connector it looks like one of the fingers (on both sides) got burned up and someone soldered some lead wires. I took off the edge connector and sure enough, those two fingers are burned off and a third is about to come off. How do you "fix" those edge connector fingers....The board is kinda flakey and if the edge connector side isn't support, the game wont boot (garbled screen, white, shows green letters MIS)... This is going to be a fun one to fix...
Then on the Reg Audio II PCB two resistors are nice and blackened toast. R29 and R30. ( I have the manual so I have the values I need to pick up) and it looks like the NPN Silicon Transistor Type 2N3055 has been replaced. Could this have anything to do with the resistors blowing? (open circuit...)
any ideas? Thanks!!!
