Hi my LG 47ln5700 tv set has thin greyish black horizontal lineson one side of the .... I hope this works good with Samsung LCD as well....

Try changing the input device to something you are sure works. Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.

It is going to be one of two basic issues:

1. There is a poor connection somewhere in the set--either with a plug or cable or on one of the boards.

2. There is a board that is beginning to fail causing this.

Either would require a shop and may or may not be worth the cause.

Having seen hundreds of these sets all are more prone to flaky problems than the older sets and average life span is 3-5 years.

Shop I work for 80% of them are 2 years old or less.

If problem began shortly after set was moved or relocated I would lean towards a bad connection somewhere.

I had the same problem with a Sony tv a couple of years ago. The cable connection was going through the VCR, then to the tv, so we thought we could try making a direct connnection, and the lines went away! I'm not sure if this is your problem, but if so, this should do the trick. If not, call a repairman, and they may be able to help.

Hello Depending how wide the line is their could be two possible causes.
I have two questions for you.
1. How wide is the line.
2. Does it run from top of screen to bottom of screen?
If the line is thin a single strait line then it is possible the PDP has gone Bad (Panel). (Screen). The screen will to be replaced.
If the line is at least 2 or more inches wide then its a buffer board which can be replaced. LG calls this board Hand insert Boards or display driver boards..

this is not an easy fix. the screen ,or the x or y screen drivers are bad .

I am assuming it goes all the way across and is black ?
It sounds like a scan line in one of the chips inside has gone bad or needs to be resoldered. Most likely needs the board replaced by a tech.
Hope this helps

I work for a auth LG service center and each time I have had this symptom we had to either change what called the T_CON control board or the Plasma display panel itself. You need to cocntact LG @ 800-253-0000 report your problem and they will find a service center in your area you should have 1 year warranty parts and labor.
