I touched the wrong button on the remote and know tv says no signal and I can't get it back

Have you tesed the batteries?

I would suggest using dedicated input button on remote, not the menu on the tv. If you can skip setup screen that would be best. I have just looked at the manual for that tv, it tells you all you need to know, depending upon which input you used for your box. As I stated use the direct input button on the remote if you have it.

You probably switched the TV from analogue to digital mode or vice-versa.

There should be a small button on your remote control marked DTV or ATV. Try pressing this.

If you are using a separate cable/satellite/tuner box from a SCART cable, turn off the tv, and turn off the cable/satellite box. Then turn the TV back on, then the cable/satellite box back on. The TV should recognise there is an external input and you should be OK.

Look for a reset button on the dish receiver its usually located behind a panel on the right side of the box, may need something small to push it in. Hold for at least 10 seconds and let go. System should reset itself and rebroadcast.. Also if this does not work try unplugging the dish box from the wall outlet for about 3mins and plug back in.

Since you are getting the signal from the satellite, leave the satellite receiver ON and press input on the TV buttons until you get the signal back, wait 2 seconds after pressing the input button. Make sure the TV is on channel 3 if you are using the antenna input.
Let me know if you need further assistance.

pull out the access card and push it back in

try to hook up signal diffrent instead of rf go video, or s video
i would try video if you have original remote see what happens

Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was.
Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.
