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?
