My problem is that when I turn on my tv, I can see multiple blue horizontal and vertical lines across my lcd screen. This happens regardless of the input used and still happens when no input is connected. At first the tv was fine. Then, from time to time I would get these blue lines but I could solve the problem with a tv shut down. Now, only the blue lines. I can still watch tv as the picture and color aren't affected, I just get blue lines on top of them...
Any advice?
Poor convergence
We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.

I have a blue lie on the bottom left part of the LCD screen. This is an LG 50" that is 4.5 years old.
what are you talking about? I know nothing about electronics? Plainspeak please?
