Question about Yamaha Music
Hi I have a Yamaha electrone hc2 that we have recently moved from one room to another and since moving it we are not getting any sound. We have checked all the plugs are in the right places and connected properly. We have also followed the startup procedure in the manual and still there is no sound coming out of it. We were wondering if you could give us some more advice on other options that we could try to get the sound to work. Kind regards Tracy and Courtney

If the power adapter is not the original adappter- check to make sure the polarity is correct- it should be marked on the keyboard near the adapter socket, and also on the adapter itself.
The keyboard should have an internal fuse- check that. Then with keyboard open, if the fuse is okay, trace the power flow from the power pack and look for broken wires, bad solder connections, stressed components like bulging capacitors, etc. It may have a burned out zener diode in the power supply regulator portion of the main circuit.
