There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done....

No power?
Unplug power cord- safety first!
open backcover
check powersupply- top center right is p.s.
top left side of powersupply you'll see 5 capacitor 3300uF 10V.
see any pop up on top? replace it All with same rate or 16v is O.K.
do not use temperature rate 75c. Use 105C.
if you know how to solder. you could save $300 at least!

SOURCE: Low volume on LG HDTV

I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:

1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.

I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.

The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.

The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.

For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf

Hope this is useful.

SOURCE: I have a brand new LG 50 plasma and a Bravia Sony

you may have to set the input value on the bravia for optical on the input from the cable box. sometimes there is more than one way for a particular input to receive an audio signal, you may have rca(red and white), a black or orange rca type for digital, and then the optical. i would suspect you have to tell the bravia how the sound is inputed into the bravia. also , just a thought.... on the cable box there should be a volume control on the front of the box........ make sure the cable box volume is ALL the way up (it is the preamp volume).

Tv comes on but no picture no menue


Sounds like you have the wrong input selected for where you have it plugged in. Turn on the TV and the source(cable box, DVD...etc.) On the remote locate the input or the source button. Press that until you get a picture and sound.

Keep getting no signal on 32 in lg


Start at the beginning:

Hook a DVD to one of the rear sets of audio/video jacks--go to that input and verify it works.

If so, hook the direct TV to another rear input and select that---if no picture that way---the box may be the issue or wrong hookup--composite to composite or component to component (most likely).

If the set works with DVD and not DIRECT TV it is not smart enough to know what is hooked to it.

In that case a setting or the connection out from the box is the problem---check on screen menu for the box in setup.

Box may need to be rebooted with it connected to set or wrong hookup of cables.

We have hdmi cord connecting our comcast box to our Lg hi def tv. we get video, but no sound through the cord. we cant get the sound and the picture at the same time


Make sure that the cable box set set up menu has the sound selection as HDMI. This is needed especially if it is a Scientific Atlantic Cable Box.
If this does not correct the problem, call LG Customer Service to get a local Service Facility to take a look at it.
Hope this helps,

DELL 42 inch Plasma TV


I have a 42" LG LCD TV and just experienced this today. Watching cable, then the screen went to black, but audio continued. I pressed the guide button on my remote and pic came on with my guide menu. But then went to black again 10sec later and has remained that way for nearly an hour. Tried switching off both cable box and TV, disconnecting and reconnecting cables, but no luck. Finally unplugged mains, waited a minute, then turned back on. Everything seems normal now after the reboot. Phew.
