Work other way around

SOURCE: 42LH40 - Problem with sound not being insync with picture

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!

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.

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.

There might be an off on switch under the lower right hand corner of the set. (feel for it) and switch it.
