Hi,
I am the new owner of a PolySix, bought recently from a major auction site. Think I have dealt with the battery damage, and have ordered new tact switches from Mouser, but the keyboard rubber domes seem to be a problem. Only about 1/4 of the keys work. Cleaning the pcb and the rubber domes (lightly) with IPA didn't seem to do much. The pattern is not regular, and I have checked the resistance at the connector using the diode position of my meter. The keys that work are low, and the other ones are much higher. I have read good and bad things about CaiKote, and the other products, such as the stuff for repairing rear window defrosters, or the Circuit Works pen. I am wondering if anyone has any long-term experience with these solutions.
The problem with all of them seems to be that it's hard to get something to stick to the rubber, and it flakes off eventually. Is there one of these that will
fix a keyboard long-term? Thanks. Looking forward to reading lots of posts here and learning about my PolySix. Any chance some replacement key contact strips for a newer keyboard could be adapted to the PolySix?
