My TV isn't recognising inputs I think.

After changing back and fortf between inputs several times, it will recognise a HDMI input (cable box). Picture is great usually for about 3 minutes. Sometimes 20-30+ minutes. Then it will go to blue screen and then shortly after, shut down. I have also tries to program channels in, but it isn't finding any channels. My city cable just switched to a digital signal, from the old analog signal. Before this, it would recognise the analog channels, but no digital. Now it won't pull in any channels. When I checked for codes, I pressed menu & device. I got 1 blink then pause then 2 blinks. It was the timer that blinked. Any help would be much appreciated. Thank you.

@bobcat88 try a different video input. Something like a DVD or game console. See if that displays properly or if it turn to a blue screen as well. Let us know


It seemed to work well with a different player, but I think it played for about 3 1/2 hours, then blue screen & shutdown.
