Samsung 40" LCD Right Half of Screen Distorted / Pixelated

I'm not exactly sure what model my tv is but I can check if needed. The problem I'm having is that the right side of the screen is pixelated, distorted with a green hue to it. The colors are all messed up and it lacks definition. The left side of the screen however looks perfect. I've had the tv about 3 years so it's out of warranty. Samsung support said I would have to call a local repair shop so I did. They said it was probably the lcd panel and it would cost $400-$500 just for the part, not including labor. I only spent $600 for the tv. Can somebody help me narrow down the problem and maybe I can fix it myself? Or, am I screwed? Thanks!

I think you are screwed. When the price to repair exceeds 25% of the unit cost I get new up-graded items. New warranty for better items

SOURCE: 40 inch lcd blue line vertical

The display screen is made of a matrix of elements connected to cables along the side and top. On your unit, some of these many, tiny connections are making contact intermittantly thus losing the elements in that area. These contacts are held in place with just pressure and if that is disturbed, you lose that line of elements. Try squeezing the cabinet of the TV on the outside at the top in the area of the loss and see if that makes a difference. May have to go inside and see if the contact assembly is disturbed or warped or something.
Hope ya fix it!

SOURCE: LCD picture distortion.

This is caused by a failure of the main board. The failure causes the refresh rate of the unit to be off creating a trailing or ghost effect. This will require a technician to replace that board though. Hope this help.

SOURCE: Samsung 32'' LCD (LA32R81B) is as good as dead

I would venture to say it is the power supply first. Capacitors in LCD power supply's frequently go bad after a year or two. LCD displays very seldom go bad and I have not seen one kill a set completely.

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

My led samsung tv has a horizontal line and the upper right corner shows a white vertical lines


Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.

Half screen distorted


Half side distorted means the problem lies between the TCON board and the LCD panel. Please check the ribbon cable between the TCON and the panel.

Tv got a black patch on the screen.. how will it go ?


If a tiny area it may be the LCD display panel itself--fatal.

If one half or screen left-right or up down it could be an inverter issue.

46in Vizio LCD HDTV distorted black picture when tv is turned on


Hi There are three things that can cause this problem. Your lcd screen, t-con board or the signal board. Most likelly in your case since you say it's only half the screen it's going to be your t-con board. You can try removing it and cleaning all the contacts and replacing it see if that helps. If that doesn't help then replace it. If that does not solve it then it's going to be your screen.

The top half of my Sony Bravia 32" screen plays as


Hi,
I'm sorry, it sounds problem with lcd panel (screen) that is defective and causing lower half distorted image. If tv is under warranty then call number written on warranty documents for warranty cover or lcd panel (screen) replacement would cost you approx 80% of new tv price.
Hope these info will help you.
Thanks.
