Vertical lines


you could have a faulty LCD/t-con ribbon connection, or a failing LCD panel. I would suggest you try and reseat the ribbon cables to the panel and t-con, if you are comfortable doing this!

I have a Samsung ln52a550. There are colored vertical lines on the right side to the center of the screen. The tv has hung the the wall for about 2 years.


This problems colored vertical lines show up to ur tv by itself?Yes.Than ur tv the board that call the T-CON decodering board it is dying and the causes.This T-CON decodering board sit in the middle in the bottom of the tv LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decodering board for the replacement.But if this colored vertical lines causes by a person or an object by forced hitting it,this tv it is not repairable only can be replacing the whole tv LCD screen panel only,not worth as a whole tv anymore if this tv require a whole new tv LCD screen panel replacement,because it will cost the same as a new tv.Tv now only can be used as salvage tv for it electronic boards as spare parts for other tvs only now.

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.
