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

The EPROM IC might be defective and might need a change but with the help of the Yamaha service.
Howeverr leave the set ON ffor several hours if you have not used or sparingly used.Sometimes moisture within the set can cause these issues which ccan clear up when the capacitors charge up or the board warms up.The interface is having some errors /conflicts that cause this conectivity.
So keep playing , do not switch off .
Hope this tip helps.

I can't solve the problem, but just wanted to sympathize because I have the same problem. My pedal is broken on my Yamaha Clavinova cvp85a. It worked wonderfully for years but finally it broke.
I'd be in the market for buying a new pedal or fixing the old one. But I've not found any suggestions in any of these forums for either solution.

The source of the noise could be many things. At real high volume levels with no notes being played, some hiss is common due to the statistical properties in electronics. At a normal listening level the hiss should be inaudible. If there is a failure there is little you would be able to do yourself to repair it. One MIGHT use circuit cooler to isolate a bad component, but it is unlikely you would have the tools to replace it as most everything is surface mounted. If you have a treble control, turn that down to reduce the level as the hiss is always up in the higher registers.
