i am running into an issue with my Fathom, once in a while the game phantom tilt... i check all the diodes/wires on the switches in the column/row of the tilt switch but nothing looked out of place. i thought the MPU looked a little suspicious so i put a weebly board in there and it is still the same... am i gonna have to replace all the diodes anyway? what else should i be looking at you think?
