LG 47lv5500 shows wrong colors

SOURCE: LCD TV with horizontal lines rolling up screen

Find someone in an area that the Company will ship to and send them the money to get the replacement board. then give them the shipping address and have them send it to you . I would be willing to help if all it will cost me is the time. You would have to take care of the E-Bay Bill and The shipping costs from my location to yours.

My LG RT-42PX11 after a few minutes the screen starts to flicker and colors go psychedelic and after some time no picture at all

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.

Hello there,

I believe the Audio/Video Inputs/Outputs could be going out .

If you are using the HDMI try the Component cables and connections or AV cables with the S-video

if you swap the cables around and the problem is still there let me know and we try a few more steps thank you and don't forget to Rate
