D-20 stuck on boot up

[lucano01]

New guy here!
I've had my D-20 for over 20+ years, and it used to work great. But last night, I powerd it up, and it won't boot! It's stuck on the * Roland D-20* LA Synth... screen. If I try a factory reset it get's stuck on the Now Initializing screen. If I try a system test... everything seems to work.

Please Help.

Thanks
