Hi everyone.
I Got given a PSR S500 it is quite an old model but it looks is such good condition.
Got it for the little grandaughter to start learning on.
There are five keys that don't play: octave 1 C#and G, octave 2 C# and G, octave 3 C#
I have had the key frame out and removed the rubber strips cleaned it all with electrical contact cleaner sprayed the the circuit board and refitted the rubber strips.
Still the keys are not working.
Any help and advice greatly appreciated.
Last but not least only half the display works,this seems to be a common problem with these keyboards.
Hi Apollo292,
The notes C#1, G1, C#2, G2 and C#3 are connected to the same wire of the diode matrix on the PSR-S500. Please check
pin #6 (wire "
N11") at the connectors marked in the attached picture (circuit boards "61H" and "61L"). If there is an interruption or a bad contact at a connector, the notes mentioned will not work.
Edit:
Please also check pin #5 (wire "N21") at the marked connectors in the picture!Hope this helps!
P.S.
Regarding the half-functioning display, I don't know how to fix it at the moment.
Best regards,
Chris
