That model is covered under a class actions lawsuit settlement over bad power supply boards. You need to contact Samsung about this and get a warranty claim started, even if the original warranty is over the settlement terms will cover parts and labor. You can get additional information about this along with contact information here: http://www.ccl-la.com/blog/index.php/samsung-has-reached-a-settlement-in-class-action-lawsuit-over-faulty-tv-power-supplies/

Your model Samsung falls under a class actions settlement. These units have defective power supply boards and Samsung has agreed to pay for the repair / replacement of the boards at no cost to the user even if the unit is out of standard warranty. This sounds like the issue with your TV. Here is a link with additional information about the settlement and how to get the warranty work completed.

sounds like bad capacitors on the power board. Very common problem. I would look at the caps if any appear even slightly rounded on top they are bad. They should be perfectly flat on top any puffing up means replace that cap.

You have a bad power supply.

The power supply for the lcd tv can have problems that don't put proper voltage to the control board. Some can be fixed others have to be replaced. a good multimeter can be used to probe for voltage . also if the backlight is burned out you can still see a very fait picture by shinning a light on the screen.

I have the same TV and just fixed it in a couple mins. The problem is capacitor # CM861 on your power supply board. It is a 10v, 2200uF capacitor. You can tell it is bad because the top is rounded not flat like the others.

do you got power regulator?
because looks like you power supply dosen't work.

you have a blown capacitor in the power supply
the little can like cap will have a puffed up top ewplace it or have it done and you will good to go
