Lg 55lv6300 has red and green vertical lines help


On other panel TV's this is known as a convergence problem. You have to get experienced help costing about $150 or do it yourself. TV's that age have this issue, and you have to open the Tv and find the voltage/convergence box with three screws on it. It usually has blue, green and red adjustment screws, with red on the right. So go for the green and red and adjust until the issue goes away.

Is my lg 52sz8r able to go 3d as in the menu it


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.

I can't adjust my convergence LG RU56nz23


Hey...
If you have already tried auto convergence under special in the tv menu and still cant get it i had your problem.

One of your convergence sensors is dead and you have to replace it if you have no experience with this kind of problems call lg and tell them your model and that one of your convergence sensors is out ask them for a tecnician they will charge around 30$ for the tecnical visit and some extra for the repair

P.S your model has to have this line in it (-) (ru-56nz23)
