Question about Samsung LN46A550 LCD TV
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.

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.
