Just noticed that the picture flashes to what appears to be an x-ray look and goes black, but can still hear sound. LG TV was purchased in March of 2006. Called LG and was told that we were simply out of luck, we did not take out an extended warranty, but also feel that this expensive of a television should last more than three years. Please offer advice of what can be done, thank you

Check within you area for a reliable LG repair center. To fix the problem of the blue, red or green vertical line you just need to replace the control board PN 6871QCH038C. The part cost about $150.00 and a honest repair center should not beat you up to bad on the labor. Good luck and Good viewing.

Check the controller board, 6871QCH038A. This board is one layer deep into the assembly after the cover is removed. Gently lift the covering circuit board back plane to access.
To do this direct a blast of cold air unto the large chip in the center of the board. If the picture comes back on then you have found it. This means powering the TV while open and this means danger to the novice. Voltage can end your life when you become the circuit path.
Order Part number 6871QCH060Q as the suitable replacement part to this circuit board.
