Check whether you have switched OFF screen. Some T V have this feature.
Check Brightness & Contrast levels in the MENU mode through remote control.

If EHT is not produced picture will not be present.

Vertical black and white bars on lcd screen

I'm not too familiar with the LG brand, but if the onscreen stuff looks fine (Volume, menus, etc.) then the panel is OK. Try a picture source other than the one you are using now (Tuner, HDMI, VGA, etc.)

1) If it's the same across all of them, then you will need to replace the main board in the TV.

2a) If it only affects one input, it could either be your video source that is bad (which means TV is OK), or
2b) that certain input port on TV is bad, which would mean you either don't use that input any more, or you replace the main board in the TV.

When my tv is playing regular cable the volume doesnt work but when i play a dvd in the dvd player volume comes out of the tv, whats wrong?

Good--sound when playing a DVD means either a setting is wrong and it can be in the set or a box if connected---it also means the audio output circuit is good.

Worst case is where sound is developed by the set's tuner there may be a problem but check all audio settings first---

My TV seem to be on wide screen and it shows half the picture, how do I set it up on full screen? No other material is connected to the TV

Hello
If your TV displays a black box type shade on the screen means that your TV may be set to "Text" mode. To clear the screen, select "Caption Off mode".
To do this, press "MENU" button to display menu functions on the screen. Press "channel up or channel down" button to select the function "CAPTION". Press "Volume Up or Volume Down " button to select the mode you wish. There are five modes that you can select; Caption-Off; Caption-C1; Caption-C2; Caption-T1 and Caption-T2. As no other matereial is connected to your TV, you just select "CAPTION-OFF". When done press the Menu button again to exit menu display. Ok.

Volume Control is horrible - Sharp LC-32SB24U

If your using a remote control, try to replace the battery. if your just pressing the little buttons at the front of your tv, the buttons that your pressing is the faulty one. you must replace all those buttons in order for your volume to work perfectly. if you do not know how to do these, just have your tv repair by a professional tv technician. by the way, the little green k that your referring maybe the volume indicator

"snow" screen, full volume, remotes don"t work

good day
due to the long time the buttons were not used, they tend to get stuck and this causes channels eighter to stay in one station or continou scanning. it could be resolved by spraying WD40 on the buttons and press it many times then dry it before operating the unit.

On the remote press down arrow (not -channel) and you'll see up industry init. go there with ch- and press vol+ and enter. let the tv like that for few seconds and the tv will go green and hopefully industry init succsesfull will be on the screen. After that unplug the tv and replug it. Done!
