Technics PR370 Digital Piano – Problem with Sound of PR 370

by Graham Roberts
(Lagos, Portugal)

I own a Technics PR 370 Digital Piano. The keyboard sounds are OK, but now it only plays the right notes in the middle range of octaves, the upper range has no sound, and the lower range plays two octaves higher and about a third up.

Panasonic will not supply a schematic diagram to assist, and suggest a local techician, but they have no schematics due to the fact that these pianos are no longer produced.

Mine was purchased in 1992, and I now live in Portugal. I do know a technician locally who could do it if he had the manual.

Any suggestions?
