can the service menu for the LG 52sz8d dlp tv be accessed from the orig remote not the service remote just installed new lamp and tv was working fine for 1 week now the lamp indicator light comes on and flashes red then shuts off


Hi there,

One possible solution to access the service menu on LG tv's is as follows with steps 1 - 4:

1. With the TV on, press and hold the MENU button on the TV front panel.
2. While holding that button, press and hold the MENU button on your remote.
3. Hold both buttons for ~5 seconds until the service menu comes up on the TV.
4. Release the remote MENU button first, then the TV MENU button.
If you are looking to reset the lamp indicator then continue with the following steps 5 - 11:

5. Press and hold the ENTER (or OK) button on the TV front panel.
6. While holding that button, press and hold the MUTE button on the remote.
7. Hold both buttons until the Lamp Life Hours show up on your TV screen.
8. Release the MUTE button first, then the ENTER button on the TV front panel.
9. Make a note of the lamp hours if you want.
10. To reset the lamp hours, press the SELECT button (the one between the four arrow keys with two concentric circles on it) on your remote.
11. It will ask you to confirm the reset--press SELECT again to confirm.

To verify you've reset the hours, you can repeat steps 1-9 above and then just press the EXIT button on your remote.

Hope this helps. Regards, James.

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!
