Yamaha psr-550 keyboard – Touch response varies with humidity

On a couple occasions, my Yamaha psr-550 keyboard has stopped functioning properly.

The whole keyboard (all the keys) stops responding to touch. Everything else continues to operate properly.

This seems to happen when it is outside and humid.

Was wondering if there is a humidity cutoff switch or something in the psr550?

It seems very odd, but after sitting for a day, (in a dry atmosphere) it will start working again.

Weird...but that is what I have observed.

Other experienced boarders here may share their opinions.

Thanks for Reading.
