Option 1
If you or your husband have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.

This link sells repacement boards for your TV. If you know which ones the tech said are bad, you can order them and replace the board yourself.


Option 3
Pay $475.00 to get it fixed. :(

I hope I shed some light on the subject for you.

Try leaving the TV unplugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

go into the menu and find the contrast: reduce the red part of the RGB until it is suitable

Go into your picture set up menu, which should be in the main menu for the TV, and change your aspect ratio.

no it is not big iisue it is very commonly happen.
U can change fuse conductor very easily.
change it.

No! have a LG service center look at it.

It is called "Thin vertical lines" and change colors depending on the background color.
It is fixable but there are several components that can show this sympton.

You will need a tech to fix it in order to save money (because you do not want to buy a board you dont know if will fix it).
Possible Solutions:
Replace Timer Control Board, if it is not fixed
Replace Sustain Board.

One of those boards needs to be replaced and I wrote the most likely first.

The only thing that can possible get rid of this is run a white screen for 30-40 minutes. Some models come with a image retention menu. A good service tech will have a white balance generator with him.

z sustain board is bad

unplug everything and replug it in,including power
