Please help! I suddenly have an octave of keys that do not work at all. Regardless of performance or scene. The same octave is silent. What to do?

If CN1 on the upper key PCB is coming up (pins 1-2) then this could wipe out approximately an octave.
Pin 1 = C#3 - F#3
Pin 2 = G3 - C4
(an "octave" ).
If this doesn't match the notes that are out - relay what those notes are and I can match up against some probable causes better.
The best thing would be to start a service event if there are keys that never work under any conditions.

Yes, the keys that you identified as pin 1 and two are the ones affected. By "coming up," do you mean the connector coming loose from the pin?
Also, how do I start a service event?
Thanks

I don't really know what's happening - but if those two pins are not connected then the listed keys won't be recognized. Could be the connector not fully seated at either end. Could be a problem with the cable. Could be connector oxidation. Less likely but could also be some problem on the PCB.
