Clavinova - faulty E & A sharp
Posted: 11 May 2011, 23:21
Hi all,
I have recently acquired a clavinova clp - 370. It all works fine except for the E & A sharp in each octave.
I don't know anything about the mechanics of digital pianos but to me it sounds like a faulty connection. I have had it apart and had a look, all the connections seem ok and the fuses on the circuit board are all ok.
Anyone know what this problem is likely to be? I tried hooking it up to an external speaker system via the phono output to see if it was a fault with the audio out (the connection wires to the speakers and pedals seem venerable so thought that might be an issue) but no sound was being output, not sure if this is a connected problem or not I wouldn't have thought so but i'm no expert, the connectors are a little corroded so am putting it not working down to that.
I have tried locating a service manual to try and narrow down the problem and understand the wiring but can't seem to find one anywhere :s
There are two sets of wire looms which emerge from the keys, one on a block of 12 wires and the other 16 - without understanding the workings I can't correspond these wires to their functions on the keys - again, any pointers?
Thanks in advance for any help or advise. If you can answer any of the items above I will be one step closer. Apologies for the newb questions...
Cheers!
