I bought a new 42" LG LCD TV and have had a few issues... first, the standard TV sound is terrible, and second, I am constantly having to to change the aspect ratio for each channel...a lot of heads cut off.... actually, right now i'm watching a football game and I can't see the score at the bottom of the screen. I've tried both the HD and nonHD channels, and all aspect ratios but still no luck.

Many LG LCD television owners report having a problem with their televisions where the screen powers on, but then lasts only a few seconds or a few minutes before powering itself off again. The problem usually occurs with brand new televisions, and in this case is inside the television itself. If your television is powering off unexpectedly, contact LG so it can be serviced.
If you are tuning from cable or satellite you need to change the settings in the picture menu look for options like "stretch" "autofit" etc. cycle through until desired picture is displayed, turn off widescreen setting if you can find it check the manual for options regarding this. If you have it attached to a computer you will need to change the resolution to something smaller like 1366X768 which is the standard 720p resolution for the smaller tv's If there is still a problem it may be
Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.
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.
maybe the inverter board for the screen issue- the power issue seems to be LG has power board design flaw- basically last time I looked the power board is manufactured NOT by LG but by H&E ...who designs this stuff??
