Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

SOURCE: how hard it is to replace by yourself main board Samsung LN-T4065

You need to do some more diagnosing of the problem. If you get sound and change channels take a bright flashlight and place it again the screen. Look for an image around the edge of the flashlight.
If you see an image that means the LCD controller board (TCON) is probably good.

The problem is probably one of three causes;
1) Inverter board is bad
2) CCFT (cold cathode fluorescent light) are bad.
3) Power to the inverter board is bad. You can also check the connectors.

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

Probably the power supply that drives the video has gone bad. Samsung recommends the TV go to a service center. If you have some skill and are willing to try, open up the back of the TV, remove the shielding and look at the boards to identify any obvious damage. Leaking or bulging capacitors, soot, scorch marks are the obvious. (Other parts can have bad solder or tiny cracks that are hard to spot.)

http://www.shopjimmy.com/catalogsearch/result/index/q/HP-R4252 has reclaimed parts for this TV. These are parts from TVs that were damaged in shipping and were only run during quality control tests. They list several power supplies for the model so check what part number is actually installed (there is usually a label on the board).

I hope this helps.

Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
