Post subject:  SP-555 is stuck

I hope someone can help with this. I'm trying to buy an SP-555 secondhand locally, but when powered on all the lights on all the pads and buttons turn on and stay lit, but it doesn't respond to anything. Also the screen shows "888". It seems stuck. Is there something that can be done about it? I tried to initialize it to factory settings with REMAIN + CANCEL + DEL + power on, but it didn't work

Have this ever happened to anyone? Does it have a solution?
