When I trun on TV (Samsung LN-T4661F 46 In), it start with half scrren dark from Right Side, time goes by being normal screen. I want to know what the problem is.

hi this could be a tab/ribbon fault, there are ribbons attach to the screen at the top there's chips installed on them. when one is faulty they heat up and make the ribbon start to flex and move causing this fault, hope it helps

We have the same problem. I am afraid it is a defect that is occuring in the samsung tv's

as i knew from my friend there is part called C1 OR C2
it is scan board connected from screen module from one side and then other side ether direct to power supply or to main analog board that got signal from main digital video board, that is what i knew.good luck search this on eBay or get other opinion.

T-Con PCB. It is attached to the panel, under a metal shield. The LVDS ribbon cable runs to it from the Main PCB. It can be purchased separately for this model. For version SS03, the PN is: BN81-01312A

The back light is beginning to fail, thats why it goes shaded but you can still the picture on one side, do a google search for back lights for your make and model, there a few how to's to help you with changing the back light.

most likely it is a separation of the layers of the lcd screen

Look in the manual for the TV and determine which platform is supported. VGA, XVGA, SVGA etc. Set your computer output to the proper mode and the unit should work. Let me know how you make out.

Ur backlight video board is dying,must replaced to solved this problem.Part and labors about $500.

The would be due to a faulty inverter that controls how much power is give to the display at a time so when these go out you will see this tint or black. So you can replace the inverter or bring it into a shop and have it replaced.

It would be about U$1,100.-,
If you could find any panel, I'll let you know later.
