Check in the manual or with the manufacturer, but the TV should auto configure the picture based on the signal.
I have a Toshiba that does the same thing.

There is no mistake when HD is in effect, as the picture is superb.

No, it would be best to call an engineer so that he can check which version of software is currently running in the TV. If you still have sound when the picture cuts off then there could be a problem with the inverter. If the whole thing is swiching off then the problem maybe power supply or main board. These tests would need to be investigated.

Go purchase a small radio from a pawn shop with aux inputs. Run the tv's audio through it form the audio outs on the rear of the tv,or from the video sources rca outs. You may have to find somewhere to set it up centered on your tv, but at least you get a better sound for a bargain in comparison to a repair.

TRY TO RUN COLORED AV COMPONENT CABLES FROM THE STEREO TO THE TVS HEADSET JACK. IF COMPATIBLE? THIS IS THE STANDARD AUDIO CONNECTION FOR HOME THEATRE SYSTEMS.

found this floating around online:


1) press and hold the menu button on the side of the TV then press and hold the menu button on the remote until the display says "Enter Password"

2) enter four zeros from the remote control to get past the password screen (you should now see an "IN START" menu with all kinds of information listed)

4) look at the lower left corner where there should be a numbered menu -- menu option 4 should say "System"

5) use the down arrow until the word "System" is highlighted (pressing the number '4' will not take you down the menu) and press the enter key (you should now be on the System menu near the middle of the screen)

6) press the down arrow to option 9 "Lip Sync Adjust" and then press the left arrow to adjust the value to zero (mine was set to 20 from the factory)

7) press the return key to get out of the menu and bingo, you're done!

This sounds as if you have a block defect which is a fault within the screen. Unfortunately the only way to repair this is for the screen to be replaced.

Clean the Lens: Use a DVD cleaning disc to clean the lens. If the problem persists, consider professional cleaning. Test Other Discs: Try playing different DVDs to see if the issue occurs consistently. If it's specific to one disc, that disc might be the problem. Check for Updates: Make sure your DVD player's firmware is updated. Refer to the manufacturer's instructions for firmware updates. Try a Different TV: Connect your DVD player to a different TV to see if the noise disappears. If it does, the issue might be with your TV. The hum is simply the player trying to read the disc. It can't so, it spits it out. Remember that prolonged use of a malfunctioning DVD player could potentially cause damage. If the problem persists, consider seeking professional repair or replacement

Maybe the disk is not compatible with the DVD player version

It can't be done. The DVD remote will be single frequency for that device only and the LG remote for that LG Blu Ray (or series) only. Companies don't make cross-control between makers easy. The only exception is cable and satellite boxes to allow their remote to also control the television.
