INTVCruise Posted June 2, 2023 Share Posted June 2, 2023 (edited) Hi guys, finally got around to testing this console I have and it does not work. It shows just a green screen with a bunch of P's everywhere most of the time. It behaves this way whether a cartridge is inserted or not. I'm guessing there's probably not much hope for the machine since I can't find any info online about repairing a broken one, but I am willing to try anything that could be suggested. Thanks!

masschamber Posted June 2, 2023 Share Posted June 2, 2023 Everything is off the shelf and socketed, so fixing it is always possible, Try replacing the ram first as I've had a failure similar and it was ram Quote Link to comment Share on other sites More sharing options...

Would the following chips be suitable to try, they were from an intellivision III board with a sound problem so I think they must be working, but don't know if they are an exact fit, I think they are also 2114 looking at a quick board pic online. Thanks for your help :). Quote Link to comment Share on other sites More sharing options...
masschamber Posted June 2, 2023 Share Posted June 2, 2023 I'm pretty sure I used the same chips in a repair 21c14e as it is what Pac-Man uses and i used the same Quote Link to comment Share on other sites More sharing options...

Thank you Masschamber, another quick question, so at first the console was going straight into 1 player mode without letting me select it, I assumed a short in controller 1 which seems to be correct, are the controllers notoriously damaged for this console?
