My LG LCD suddenly became stuck on one channel. The audio is fine but the picture is frozen. I cant get the TV menu to come up nor can I change channel. It takes a good few seconds to turn off and when I turn the tv back on it takes a few seconds for the picture to appear. The picture is normal for about 2 or 3 seconds then freezes again.
Try One of your working TVS and connect it to your cable outlet of the TV that is having problems. If that TV Does not work then there may be a degraded fitting or the Leg coming of the splitter to that outlet could have a Low Signal Problem
Next Take the First TV that was not working properly and put it on the cable outlet of one of the TVs that is working properly and if the TV set works on that Channel then you know it is not your TV that it must be the cable

The mts/sap function on your television might be enabled. Locate the audio settings on your television and make sure you are set for either stereo or mono. You may have an audio or mts button on your remote. If not this should be in the menu.
The cable company may have made a recent change and the tv may need to be channel buffered or you may need to complete another channel scan.
Hi, I disagree with info provided, if screen of your LG lcd tv becomes green that means inverter board is working and lcd tv does not have convergence ICs. Please unplug tv from ac wall socket for minute to get it reset, replug back in and turn it On and check its picture. If still showing green screen then change input source with remote, if tv shows same green screen on all inputs that means its either lcd panel problem or digital signal processor got bad loacted on main board. Local tv repairman is needed to confirm and fix it. Thanks.
Well the LG tv is not getting the cable signal.Unplug the cable box about an hour.Replug the box let the software to upgrade the cable box.The LG tv should get the signal back as normal.Not,than the LG tv Tuner board have problems it dead.Tries Websites like Shopjimmy.com,Ebay.com to buy a refurbish Tuner board for the replacement.
Sounds like you have a bad signal from the antenna or the cable. Unlike analog TV if the signal level drops below a certain level you loose the picture and sound completely. The fact that digital channels are detected during channel search does not mean they have a good signal. Try moving the antenna about.
