Push the input button until u get a picture. If that does not help, then make sure the RCA cables "red yellow and white" are still plugged in. Or whatever cable u have that goes from the cable box into the TV.

If your LCD TV or monitor has stopped working, or is displaying one of the following
symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can
examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life
of your monitor or TV by several years.
Take it to a repair shop.
Try changing 'perspective' or screen ratio.
This may work, but could also stretch the picture too wide,
On my non-LG TV this is called 'aspect ratio' under the 'picture' menu.
Look for loose contacts in power outlet, RC Jacks, sockets, cables. Change input device to some other like a DVD that you are sure works. Swith off TV, switch off power, remove plug and retry after 48 hours.
If problem persists, call in a qualified service technician.
Sunds like a tv issue. I would try to connect a dvd player or vcr to it to see if that works to eliminate the service provider first, if it still doesnt work its the tv.
You have a problem in the video circuit. Any video that comes into the set is not getting to the picture tube. The menus come from the system control microprocessor. This shows that the input at the picture tube itself is working. Also you system control is working.
The signal would have to be traced through the set to find out where the loss is originating.
