Hi I am new so please be gentle. I have AP80R electric Piano with some keys which are intermittent. I have opened it up and it appears that the board has some signs of corrosion.

I have cleaned it and would appreciate next steps. Whether broken tracks can be repaired by applying conductive glue? how to identify where faults are?

I have attached a photoenter image description here

Thank you

Pit

  • Just solder thin wires (like these used for wire-wrapped circuits) to bypass the broken conductors. – Eugene Sh. Feb 22 '18 at 14:52
  • If I run conductive glue over the brownish tracks, will that help? – Pit Feb 22 '18 at 15:03
  • Depends on the glue, I guess. I suggest you go to YouTube and find some repair videos by "8-bit keys" and others. Watch and learn. Come back when you've got the basics down. – Dampmaskin Feb 22 '18 at 15:12
  • No way to tell. Conductive glue might have too much electrical resistance and not connect the signals properly, and if you touch one track on another might be a nightmare to find out (i.e. high resistance intermittent glitches). – Wesley Lee Feb 22 '18 at 15:13
  • Thanks, I 'll check our relevant you tube videos. so would you say that soldering thin wires to bypass the broken ones are best solution for now? – Pit Feb 22 '18 at 16:03
  • Would you solder thin wires just on brownish / damaged tracks? – Pit Feb 22 '18 at 16:04
  • Ah those crazy drunken nights sat around a piano singing and spilling vodka over the piano. Those were the days. – Andy aka Feb 22 '18 at 17:02
  • Andy. I bet you are right. I have bought the piano second hand recently. The boards have screws. Can they be replaced? I have watched the you tube videos incl "8 bit keys" but do not have solder kit, tools etc – Pit Feb 23 '18 at 07:26
  • Eugene, do you mean wire wrap similar to the one on last photo , link https://www.jameco.com/Jameco/workshop/techtip/wirewrap.html – Pit Feb 23 '18 at 07:45
