I have exactly the same problem with the same model tv. I am currently scouring the internet to try and find a solution to fix this problem. If you find one before I do, please share your findings and I will do the same. It has been suggested that it could be capacitor failures in the power supply unit. I have not looked at the psu yet to see if any capacitors are "bulging" I want to be sure before I start changing components.

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.

I loose my picture but i still get sound


Just try to reset so picture will come again, some LCD TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the LCD TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the LCD TV power button for five seconds.
4. Plug the LCD TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the LCD TV is responding again.
6. Turn off the LCD TV and reconnect the devices.
7. Turn on the LCD TV.

Hope it may help you;

Very louud buzzing from LG LCD TV 42lg50


Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

LG 42 LCD no sound or picture


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.
