Hey guys,
I have two boards that have brought back from the dead via a donor board, but neither are 100% working...yet. A bit of history, I have installed cap kits for both chassis. I have checked every single solder point, and re- flowed the suspects for both chassis. I removed and checked X301, X302, X303, X304, X305, and X306 for both chassis. I have checked the resistors known to be suspect for human error (R303, R306, R314, & R317) for both chassis. I have replace capacitor C303 with a 10uf 50v cap, and moved the C303 cap to C501 for both chassis. I have tried every combination of sync wire configuration, and have tried multiple game boards. I am about to replace IC501, but I only have one on the donor board, so if that does not work, then I am stuck. Please help. Any other suggestions.
Thanks guys,
Greg
