I was given a Kurzweil RE-210 piano and was told that the 3 lights in the small screen just blink when is turned on. When I got it home and set up, I turned it on and it worked great! Next morning when I turned it on got the blinking lights. After 3 tries at turning it on, it finally operated normally. Today I get the 3 blinking lights. Haven’t been able to get it to come on yet.
