My vizio gets green lines across screen and looses sound after about an hour of operation sometimes with loud buzzing noise. Help!


Since the video and audio both are affected, we have to assume it is in the central processor next to the tuner, which separates these two. I suggest you note down the IC numbers, look for its datasheets and study what are the functions of each IC. Then look for any leaky/dry capacitors or dry solders in the board in the surrounding area of the IC. What I normally do is to replace all the electrolytic capacitors in the boards, if the TV is more than 5 years old or its use is so extensive. It is proved from my experience that the TV works like a new one for many more years. But you should do this only after ensuring that the TV is brought back to normal working condition. And, this requires a lot of patience and precision work, lest the boards should get spoiled.

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.

My polaroid has sound and picture problems


This is a well-known problem with many Polaroid FP displays. Eventually, the picture will simply go black, rendering the TV useless. The solution is a new control board, ~$400.
