Check the DC adapter. It may be shorted/broken. This type of stuff happens sometimes.

I just experienced my p85 with a key problem on the F# below middle C. You will need to disassemble the keyboard and usually the keys are groups of 6 - 8 keys. If you remove the group that has the problem you might be able to find the problem visually. Mine just involved removing and reinserting the F# key back into the assembly. Then reinstalling the group of keys. If you can't get the key to work properly, you will probably need to buy the group assembly from Yamaha.

What adapters have you tried? The P85 REQUIRES a 12 VAC adapter, NOT the common DC type and it needs a 1.5 amp (1500 ma) type adapter. If you connected a DC adapter it will NOT do damage, the unit just won't work. You can find adpaters on Ebay or Google search.
