B Button Not Working GBC
Hello friends, I recently bought a pretty beat up Gameboy Color to do a mod on. This isn’t my first mod, and I was excited to put a more modern screen into the GBC. Before I got the parts for the mod I took apart the GBC and cleaned it up, including the board. The rubber membranes were pretty beat up, it seems someone played this GBC a ton. The B button wasn’t working when I first tested before cleaning, so I knew the contacts on the board would need to be cleaned up to ensure better button presses. After cleaning, I put it back together and found that the B button still wasn’t working. I ordered new rubber membranes and cleaned the contacts several more times with IPS to make sure they were extra clean. However, with the new rubber membranes the B button still isn’t working. I don’t know what else I can do to the contact. I lightly scraped at the contact thinking there may be residue from the old rubber membrane, but that hasn’t worked either. Does anyone have ideas of what else can be done?
Ist dies eine gute Frage?

The traces on the PCB could be messed up. Try going in there with a multimeter and testing the continuity between the button contact and the test point. The test point for the B button is the one directly above the "WR" label (pin 3) of the cartridge socket.
