Try changing from channel 3 or 4 and run a New Channel Search

You need to boost your signal somehow, get a better antenna. nothing is wrong with the TV, this is a typical Dropout when signal is low.

I had the same problem, same channel, same day. It must be a problem with signal strength. With the TV on, I unplugged the coax cable that leads to my antenna (I am not on cable). As soon as I disconnected the antenna, I could change the channel off of 11.1. I plugged the antenna back in and all other channels work. Hope this helps.

Check antenna cable setting in menu. If you have it on antenna and cable plugged in, you will not pick up anything past channel 13. Change it to cable setting in menu.

This is my second set in as much days from Best buy. Exact same problem.
I just bought 32 inch 2 hours ago, and am using it with an antenna. Almost every time I turn to channel 5, the remote freezes and I can't even use the buttons on the side of the tv.

There isn't a tv signal on that coaxial cable. The other end of it is not connected to anything with an active signal. For example an indoor antenna, or an outdoor antenna, a cable TV company's active TV source (that you are payin for), or a satallite TV company that you are paying for them to turn on, also TV's do not have a built-in satallite tunner to tune in those sattallite channels, you have to use that company's external tunner box. No tunner box = no channels. Even U-Verse No Tunner Box = No TV.

if this is an older tv and your state might have changed to digital programming then i would suggest trying to look at the back of the set and see if you have anything to fix this problem or you might want to CHECK AND SEE IF YOU HAVE VIDEO ON or CABLE on or TV on. Sometimes if you have Antenna switch to cable then your channels would be red and picture distorted. change the antenna to air for tv. or from tv to cable.

You must unplug the cable connecting the television and the cable box. Then turn the television off and then back on. Do not turn the cable box off or disconnect the cable in wire from the cable box especially if you use Cable Vision. It will take up to 20 minutes before the box comes back on. Now turn the television back on. When you access the Channel System menu, you have the access to the submenu choices. Change the Antenna option to CATV and the Current Channel to 3. Reconnect the cable box to the TV.

Also those that are having problems with the TV turning off periodically, make sure the sleep mode option does not have a number in it. For example, if the number is 10, it will turn off every 10 minutes.
