Andy 2 keys not working, also no velocity...please help |

Hi guys,
I just bought a second hand andromeda with all voice intact an in tune, but 2 keyboard problems.
-2 keys(next to each other) are not working.
-Velocity doesn't work at all
I tried a hard reset (softbutton 3 turn on), didn't work
I changed velocity paramaters.......didn't work.
So I took out the keyboard and blew some compressed air at the 2 keys.......didn't work.
Do any of you guys know how to fix this?
Or do I have to replace the keyboard itself?
Thanks. |

Ok...next day
Velocity is working after some resets.
the 2 keys are still silent.
I took it apart and cleaned all the rubber contact strips......still not working.
Could it be the diodes on the keyboard pcb?
When I measure the diodes they all seem to give the same value.......do I have to desolder them to be able to measure them properly?
Please anybody? |

I found out wat was wrong.
Two of the carbon pads beneath the key rubber, are not in contact with the acording pcb traces.
So I bought some conductive glue to try to fix that.
I'll post the results of this operation soon. |

instead of glueing i'd prefer letting a technician chance the rubbers . not too expensive and more futureproof then glueing ( b.e. how to remove properly in future when neccesary when glued? )
normal aging thing for keyboards, small service thing... |
