TV will be working fine, then all of a sudden, no picture and 'no signal' sign comes up. This can last anywhere from a few minutes to all day. Sometimes cable signal comes back, but still can't get digital or analogue signals.
Have had digital antenna installed. all other analogue tvs work as does cable in other room. Also, when this happens, if i try to watch recorded tv, i get a picture, but there is no sound.
To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.
If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.
All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru

After turning on my LG 42 in LCD tv the unit turns off inr 7-9 seconds! no sleeper set no auto off
Found that TV started switching off by itself. Would try to come on..green light blinked for 2-3 seconds, tv came on (with picture and sound) for 1 or 2 seconds and then it would turn itself off. Found that the issue is with one channel only. If you are facing this issue....try quickly changing the channel the moment it comes on. You can do it either with remote or with the TV buttons directly. also in the same logic, if this is still happening, try changing the source to another (rgb-pc, av1, av2 etc). Basically change it from whatever input it is on currently, if changing the channels does not work. My symptom was that the tv made a loud 'TIK' 'TAK' sound which is louder than normal.

46 inch LG HD flat screen TV the speakers seem to have a slight vibration that distorts the voices. It does not occur with every word but often enough to be a pain.
I have this problem with my 37LG30.
They all seem to have the same factory flaw.
The plastic bezel and rear is vibrating against itself I have found.
Tonight, just now, I just took all the front bezel screws out,(from the back) loosened the other 4 big screws in the rear center(I don't recommend removing them)and loosened the stand screws also and tried separating the bezel from the back as I went around the set. This did not really help much except around the bottom where the noise/vibrating comes from-the speaker area.
The two plastic pieces are vibrating against one another.
The vibrating was coming from the speaker area without doubt.
The next thing was to try separating at the bottom where the speakers are with my fingers and a stiff metal nail file carefully..fingers seemed to work best for me.
As I separated the front bezel from the rear housing (at the speaker location)most if not all the buzzing/vibrating /distortion went away.
I then inserted small pieces of cotton (you can use felt, or similar I suppose) and buttoned it all back up;put the screws in
Almost all the distortion and speaker buzz/vibratingis gone except on very low frequencies.
good luck!

when i connect my dell inspiron laptop to my lg 42 lcd tv it keeps saying on the tv invalid format this should be a plug and play but it does not work and im clueless how to get the format the same any help
Go into your control panel. Select display. There will be a picture showing 2 screens. Select the 2nd screen, and lower resolution to it's minimum. Apply and test. Slowly increase till you find what your happiest with. Worked for me using a ASUS laptop and LG60'plasma.

Hi - We have an LCD tv (32 in.) that we have had for about a year and it just displaying yellows and greens strangely (e.g., green baseball fields look like a pale avocado color and people's faces look yellow). We tried adjusting the color controls but it didn't do much so we went back to the default. Any suggestions? Thanks so much!
Just like in Solution 3. Color was off. Looked in back and cables "appeared" to be ok. However, I disconnected the cables one by one and amazingly the color returned. So make sure your color cables are truly connected.

LG 42LC2D 42 IN. HDTV LCD TV SENSOR IS NOT WORKING.
Believe it or not...THIS WORKS!!!!
Look on the back of your set for an external remote jack. It should be the same size as a small headphone jack. If it has one, use a spare headphone plug or your headphones, and plug them in and out about 50 times. This will clean the tarnished contacts and make your remote sensor start working. Your remote sensor goes through a switch on this jack.

My Samsung LCD TV 40 in is only 3 weeks old but has developed a vertical red/pink line on the right side of the screen
Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan
