Question about Yamaha P85 88Key Portable Digital Piano
Power button turns on but will not turn off; will only turn off using the electrical cord. Master volumne button works but all other buttons do not work. Is reset using the highest C while turning on standby button?

1) Try a partial reset by holding down the last white key while turning the unit ON.
2) If you haven't recorded any performance(s), for a full reset, hold down on the last white key AND THE lst three black keys while turning the unit ON.

There are flexible cables that connect the keys to the main electronics. The connectors for those cables sometimes age poorly..
It is fixable. But dont "get taken" on a repair.
If it's just resoldering a few points,it shouldnt be more than $100.00

Plug in your ear phones to see if you can hear the sound that way. If not you are experiencing some internal failure in your integrated amp output.
In that case you will need to get authorised service.

Without power to the unit no sound should be generated. Make sure there are no other connections.
MAYBE you have a wall transformer behind it that is buzzing. MANY wall transformers develop buzz.
Another source is flourescent lights and even some of the low voltage halogens have noisy transformers in the base.
