Icom A210 failed again

My Icom A210 radio failed, again, but this time in flight. Now when I turn it on it just displays <Icom 1.63.00.1> and nothing happens. Has anybody had this problem before? FWIW, the radio was sent to Icom for repair about 4yrs ago and has not been removed from the airplane since then. Just for "giggles" I checked the ribbon cable and even replaced it with a new ribbon cable. That didn't work.

In the mean time my "old" Icom A200 is back in so I am not grounded. It works perfect and has been that way for 12+ years.

I have one of those A200 thats used for exactly the same thing. BUT, I also have a GTR 200 and wiring in the cabinet thats waiting for that "next time". Good luck , let me know what icom says.
