    I have the same problem - a 1" to 1.5" vertical blue line has just shown up about 6" from the right side of my LG DU-42PX12X. What caused this, and can it be easily & inexpensively fixed? I've had the TV for 3 years.

Without troubleshooting the set, I will take a sort of guess at what I think the fault may be.

This may be a fault in the video processor, most likely dealing with the RAM, or part of clocking drive for the modulation decoding that is driving the display panel.

The fix is board replacement.

Thick color lines on screen


Hi ,Sorry, this is not a solution. I have a question about your line. Is it transparent? (can you see through if the picture is bright)Does it remain there all the time if you change inputs? My LG 42" just had a blue transparent line appear on the right side of screen. Tried a few trouble shooting things w/ no change. About 1 hour later it went away. Did you find a solution and what was it?
