Trying to fix a sick Yamaha TX802

Hi there, I have this synth that is in good shape physically. Even the screen has a nice backlight still. However it's general behavior seems off and i'm wondering if maybe the EPROM could be the cause.

I made this video to see if anyone could verify. i can say it does make sounds, but it seems like programming was the part that's out of wack. the backup battery had been replaced as well so it's not a low voltage things.

EPROM fix would be so nice.
