HI WHEN WE TURN OUR LG 42 INCH LCD TV ON IT WORKS OK FOR ABOUT 30 MINUTES THEN THE PICTURE GOES AS THE SCREEN GOES WHITE THE SOUND WORKS FINE AFTER ABOUT A HOUT THE PICTURE COME BACK AND IN OK ...


I suspect you have a poor contact on the video processor board or the upscaler itself on the screen.
Check all ribbon connectors and look for any components that have got very hot, there may be a dry solder joint beneath them.
Hope this helps.

Why does it take 10 minutes for my LCD Legend tv


Sounds like you have a faulty capacitor on your invertor..Gently press on the screen when there is no picture.is there light on the screen? If so, there is backlight but no video..hence a mainboard or power supply problem..If there is no backlight then the problem is the invertors or the power supply not supplying 24volts. The invertor is located on left or right hand side of screen..Check that all connections are secured and not loose.Check that the power supply capacitor tops on the power supply do not have bulging tops..If not, and voltage is reaching the invertor, then remove the invertor and check for bad solder joints and leaking capacitors.
