PSR S770 no sounds or button control

[Neil Osborne]

Hi gang, before I return my S770 (only 2 months old) I was wondering if anybody has, or has solved the following issue.
Press power button, boot screen, home screen, all ok but:
Instead of 1 audio "click" it plays 2 clicks.
No sounds, nothing when I play keys, no button lights, nothing happens when I press buttons, no access to anything.
This happened a couple of weeks ago and after a few on/off power attempts I turned off, unplugged power, plugged back in and it was ok.
This time I've turned it on/off 20 times including unplugging from power.

Sounds like it may be the output solenoid acting up.

Since it's under warranty I'd definitely get it looked at by Yamaha for their nickel.
