Hello All, Found an issue shortly after receipt of my M102 where the 'C' key doesn't work anywhere (BASIC, TEXT, ... ) which unfortunately came up a lot lately when needing to type CALL or SCREEN.
Pulled the key cap off and cleaned with IPA - touching the metal pads inside the switch doesn't work so carbon paint wouldn't help. Resoldered the connections under the board without any luck. Hitting the two bottom solder pins does work so not a trace problem. Before I have to take all the keycaps off to get to the top of the board, is there anything between the soldered points under the board and the metal pads on top that could be bad? I notice the solder points underneath don't like up exactly to the top. Regards
