You'll need to go into service mode and do a factory reset.
To enter service mode you'll need to press these buttons on your remote in the following order:-
Standby-info-menu-mute-standby.You'll need to do it fairly quickly and be patient it doesn't always go into it first time,don't press and hold the buttons.
The service menu should appear on the screen.Use the up /down cursor to scan down to option number 12 (factory reset)and then press the right cursor wait will appear on the screen and the set will go to standby(don't worry this is normal)
Reboot the set and retune and all should be well

To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.
If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.
All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru

Thre 24vdc power supply or backlight inverter boards may have gone out, those are the places you ned to check first.
First, look at the screen in darkened room to see if you can see any slight glow from the screen, if it does, then the problem can be the T-CON (not getting the 12vdc) or the main logic board not feeding the signals to the T-CON board.
if not, next place to check will be the power supply module, make sure it has 24vdc which is required by the backlight inverter to work, the reason for not having 24vdc can be from bad DC filter caps (leaking/bulging top, high ESR) or short circuits in the inverter board which will cause the 24vdc supply to go into shutdown mode, so you may have to disconnect the power cable that feed the inverter board to see if the 24vdc will work without the inverter board hookup, you will need to apply about 3~4 amp of load to the 24vdc to make sure it can handle that. There are fuses on the backlight inverter boards also. So there are some troubleshoot you will have to do to find out the causes of the problem you are having.
