    My 42" lg lcd loses the picture after about three minutes, but it still has sound. The green power light will finally turn red and the tv shuts down.

    When I turn the TV on, it keeps clicking off and on continuously and I cannot turn it off. I have to unplug it and plug it back in and it will stay on. I have searched the LG website but have found nothing related to this problem.

There is probably a firmware update on the LG website that should take care of this.Go to the downloads area and enter the model number for available updates.

    There is a safety feature on all larger LG LCDs that if the unit is to full of dust to let the fan cool properly or the fan is to full to operate at full speed the TV will not turn on it will flash green when powered on then click and go to red. I brought mine in the first time it cost $50 to get it cleaned and reset. If you are electronics sauvy its not that hard to do your self . Hopefully its that simple for you as well other wise these are all good places to start.

It shuts off 2 seconds after i power on.
Several possibilities but most common seems to be power supply defect or poor connection. Check these resources. Note that other Youtubes that may address the problem are also accessible from the youtube link.

LG LCD 42" sound but no picture
From this web site it says:
http://www.ehow.com/about_5379235_lg-television-problems.html
 Powering Off
  • 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.

My TV turns itself off within 5 seconds after I turn it on. Whether I use the remote or turn it on manually it shuts off.
I had a similar problem with my Phillips 42 in. LCD HD TV.

Here's the problem. The Power Supply Board. I opened my TV up(warranty was up of course) and found several bad capacitors. Phillips and several other companies were sold capacitors that although were highly rated failed within 5 years because of a lack of preservatives. All sorts of electronic equipment is now being effected due to these defective capacitors.
Solutions?
1. Take it in and have it fixed
2. Open it up, check the board for faulty capacitors(bulged or leaking) Buy a new Power supply board and install it.
3. Remove PSB, remove faulty capacitors and replace with compatible new ones.

Hope this helps

I turn on my TV on and within 3-4 seconds, it turns itself off.
  1. Might have a power supply issue take the back off and see if there are any bulging caps on the power supply board. If you dont know what your doing call a tv service tech.
