try first if you have not to remove set and any cable or sat box from power, a box etc can cause this--when you plug back the units will try to reboot, cannot hurt and may help.
Have you tried to push the tv input button? Sometimes when a button is buy accident it changes the input on the tv. Hope this works, let me know. Good luck, Toni
Try going to the menu and changing it back from there! If all else fails then just keep pushing every button on the remote and im sure you will hit the right one!!!!
GOOD LUCK!!!!!!!!!!!!!!!!!!
HAPPY HOLIDAYS!!!!!!!!!!
Sorry I see the model, hold the Menu button on the TV (not on the remote) down for three seconds. Note: Shop Mode is activated in the same manner: Pressing and holding the Menu button on your TV for three seconds. To avoid accidentally setting your TV to Shop Mode, avoid pressing and holding the Menu button on the TV for three seconds or more.
Had the same problem. The solution: My remote has a button labeled "TV/VIDEO". I must have accidentally pushed this button so when I turned the TV on it was searching for the signal from a VIDEO source. It couldn't find the signal so it's programmed to automatically turn off if no signal is received. All I did to solve problem was I turned TV on and before it could turn off by itself I pushed the "TV/VIDEO" button on my remote to switch it back to receiving TV signal.
Tried to use my TV as a computer monitor. When tries to boot up, will go to "No Signal". All hooked up correct. Is ther something I need to do tobe able to use the monitor with my computer. I have a Dell Desk Top Computer.
I had accidentally pushed the button for resolution so the resolution was to low.
I repeatedly pushed the button until I got back to the resolution that the DVD player needed to be at. Thanks.
Have you tried turning your cable box off, given it 3 minutes then turn it back on. We have Time Warner Cable and their remote has the tv and cable buttons at the top right of it and sometimes that helps. Good luck
