T2 Stopped working. It Displays this Message On TV “Mode Not Supported Please Change the resolution.”

The last few times when turning on T2 the TV would show this message. Rebooted by pulling power cord on T2 and it booted up and worked. No longer works. There is nothing but this message and black screen. Cannot see menu. Tried pushing resolution button on lower right corner of remote to no success. The T2 light blinks but no display.

Is it likely my T2 is toast?

Anything I should try?

Open it up replace a part?

order a new box?

thanks in advance....
