My 52" Samsung LCD/HD TV (Model Number LE46A557P2FXXU - Version AA01) is having major screen problems. The entire left hand side of the screen is under a dark shadow and very blurrey with horizontal lines across the top however the right hand side is fine. This has now been ongoing for a few weeks and initially it appeared that once the TV had warmed up it gradually disappeared however this is no longer the case. The TV is only 4 years old. Any suggestions?
T con board failed if its half and half. can also be a lose cable on the screen to the tcon board from the lcd screen side. Tcon is in the middle off the screen on the back.

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

causing of horizontal lines is leaky or defective capacitors. check big value capacitors around the board at Horizontal area. check the filter capacitor as well. good luck

Need to check the two things.
1st -- need to exchange T-con Board.
2nd -- need to exchange the cables between T-con & LCD panel or
between T-con & Main(LVDS cable)

I have the same problem, currently searching for a solution. Have you resolved your problem yet? Looking to repair myself, any tips or ideas that you have/expirenced would be greatly appreciated. Thanks, Todd

Based on reported problems with Samsung LCD tvs, It is probably one of three problems:
Separation of layers of the LCD panel;
A defective LVDS cable connection;
A defective T-Con circuit board.
If light hand pressure on the affected area on the LCD panel changes the problem, its the defective panel. If not, manipulating the LVDS cable will reveal the cable defect. If not, coolant spray applied to the T-Con circuit board should reveal if it is defective by temporarily alleviating the problem. Dont remove the back cover if you dont know how to protect yourself from electrical shock hazards. There can be more than 1000 volts in the backlight inverter area.
