Most likely failed capacitors in the power supply. I recently had the same problem with my 26 month old Samsung LN46A750. Samsung paid for the installation of an upgraded power supply board.

If you shine a lamp at an angle on the screen, can you see a faint image? If you can, then the backlight has gone out. If your picture has acquired a pinkish tinge while it is working "normally", this would be a strong indication that one of the fluorescent tubes in the backlight is going bad. Inverter failure is another possibility.

Samsung has a 1 year warranty. The catch is that you have to take it either to the dealer or to a factory-authorized service center to collect, and "The original dated bill of sale must be presented upon request as proof of purchase to SAMSUNG or SAMSUNG's authorized service center." You need to contact Samsung Customer Service before taking the TV in for repair.

This is usually caused by either the main circuit board or the cable or it's connector that links it to the display assembly.

It should work fine on 220 volt if you get the right power cord..that means the TV can run on anything from 110 to 220 volt, its common with switching power boards to be this way

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
