There is a DTV/ATV button that switches between analog and digital tuners. Using the source button doesn't change it.

check the video cables inputs on the back of the tv. they might be plugged into the outputs instead of the inputs....try switching from av1 to av2...

causing of horizontal lines is leaky or defective capacitors. check big value capacitors around the board at Horizontal area. check the filter capacitor as well. good luck

Your remote control need cleaning. Check this site 'Electro-help" where you can find details about how to repair or clean a remote control. Google for it.

Hi,assuming you have the volume up on your receiver, and on your TV, the problem must be in either: The A/V sockets on your TV = try another set of sockets (eg: AV1, AV2, AV3,etc)
The scart-to-AV lead supplied with the receiver = take it back to your supplier.
The receiver itself = take it back to your supplier.

Note, though, that some new TVs have so many A/V, Component, S-Video sockets on the back that it is hard sometimes to work out which audio sockets go with which video socket, so you may have (for instance) the yellow video plug in AV1 while the red & white audio plugs are in AV2.

Hope you're able to sort it out.

Also, check the 'mute button' if your using those cheap black scart leads, please get rid and buy better ones as they are only to get you started and wear out quickly hence your problem..

You can do the old Sky trick of pulling the power cord out for 30 seconds and that did the trick.

Solution that worked for me:

Beware: Although the process should be safe, it technically voids your warranty.

Enter the service menu:
1 - turn of tv with remote
2 - press and release in the following order on the remote: Info, Menu, Mute. Make sure remote is pointing at the tv
3 - turn on the tv from the remote
4 - you will see the service menu. using the down arrow on the remote select the Reset option. Using the right arrow button at this point will do a hard reset.
5 - Wait a few seconds, turn TV on
6 - you will have to rescan analogue and digital channel but it should be working now.

LCD display may have moisture on tinoxide which can be burned off in low humidity room. LCD tft may be leaky, which can be burned in by standby for a few weeks. Video output semiconductor IC may be needed burn in for a week. Most of these problems are due to moisture in the air, and lack of use of the TV. Have power on 24/7 may solve the moisture problem.

Hello,
You most likely have a backlight issue with this TV set. Could be the inverter circuits for the backlights. The inverter is the power supply source for the backlights. there could also be a screen driver problem. This would entail changing the entire board. You should call in an authorized LG repair center to check this set out for you. Good Luck and please let me know what you found out about this TV set.
