Unfortunetly, this part has been discontinued by Panasonic. You may want to try ebay to locate this item. The part number you are looking for is TY-ST42PX5W. Good Luck!

Try unplugging the DMR-E85 power cord. It is important that you unplug it from the back of the recorder, not the wall. Leave it unplugged for 10 or 15 minutes. For good measure disconnect the cable 'in' connection as well. Once both lines are plugged back in it will go through its self-check diagnostics. Leave it alone for awhile (give it time to consider the error of it's ways). If you are lucky, when you turn it back on it will ask you to verify the channel lineup. If this does work, and all the channel info is correct, press 'enter' (lineup 1 highlighted). Good luck! This is an awesome machine, WHEN IT WORKS!

Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board.
The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 minutes so the TV can reset itself.
2. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.
3. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

Press and hold "Setup" until TV/AUX blinks twice
Enter 9911 and press "Power" using the Comcast remote
Press "Channel Up" until device powers off
Press "Setup" to lock in that code
