Help! Blown fuse or power supply in Roland electric piano?

I have an old Roland RD300s electric piano. I was playing it the other night and the sound suddenly crapped out, then a few seconds later the LEDs all went out. I unplugged it, plugged it back in and tried to turn it on again. The LED's stayed on for a second, but still no sound came out and then the LEDs went out again.

I'm guessing it's probably the power supply, maybe a fuse. Does anyone have experience tearing one of these things apart? Does the back panel come off easily? I'm decent with electronic repairs, but I'm afraid of accidentally getting into where the weighted keys are and messing something up.

Any insight would be much appreciated. Thanks!
