SOURCE: multi coloured vertical stripes on plasma screen

With half of the screen working, and with a Plasma tv. I will look at the driver board as being bad. Take the back cover off, the driver pcb will be at the top or bottom of the set. They are only about 2 inches tall and will cover most of the lenth of the set (2 boards that run end to end). The board that is on the side of the tv that is bad is the bad board. Replace that board or have a tech replace it.

Your Power Board is going bad. I think this set has a one year warranty on parts.

SOURCE: LG LCD TV - Buzzing Sound and Faint Horizontal Lines

From your description, the sound you are hearing is the inverter(s) that drive the back light for the LCD screen/module.
The inverters mounted on the back side (one lower right and one left side) of the LCD screen/module. They are under the sheet metal cover/shields.
The inverters are going out and or the LCD screen/module is going bad too.
That LG TV has only a 1 year on parts and labor from the date of purchase, but you could call LG and ask for their help for such a new TV. They might do it under a warranty, for little or no cost to you.
I hope this information has helped you.
Good Luck.

LG LCD Tv has sound but no picture only colour vertical lines. Can be fixed?


If your screen has a picture in the left corner with a small square with lines on it but still has sound...try this....

unplug your TV itself from the power source, then hold down the power button on the tv itself for 1 minute, then release.... Plug the tv back in and see if the issue is resolved. I just called LG customer support and a woman walked me through this process and it fixed the issue !!!! Hope this helps..
