SOURCE: Replace Main Board?
If he is familiar with soldering, try opening up the set and reseating all of the connectors and cables. Then look for poor solder connections and resolder any that appear "bad". Update this with the results.

I had the same problem. I live in NJ and called the local authorized "service provide" listed on the Samsung website. What a joke. Quoted $350 just to show up, never showed up. So I opened my own TV. Took off the plastic back (10 screws) took off the large metal RF shield (12-14 screws) and noticed a blown component. The markings on the component were KL15L and it is apparently an NTC Thermistor. Obviously it got fried and not knowing if there was other damage I decided to set out to replace the entire Power PCB Board Assembly and not the component. There were two part numbers on the assembled board (BN97-00457E & BN94-00622E). After searching online I also found a suitable replacement number for these (BN96-04896A). I found two places who claimed to have the part or have it on order (shopjimmy.com and vancebaldwin.com). After placing orders with both and having neither come through, I broadened my search and found out that the LNR409D was basically the same model as my LNR408D so I looked for its Power PCB Board Assembly part number which turned out to be BN41-00521B. Google search for that part number showed the item available on ebay. I bought it a week ago (ebay 260311519904) for $144 plus $12 shipping. I removed the bad board an hour ago (6 screws about 7 connectors) installed the new one, plugged in the connectors, replaced the covers, plugged in the TV... AND IT WORKS!
Suggestion: If your TV is out of warranty then open it up (what have you got to lose) and see if the problem is obvious and maybe something you can fix (replace) yourself. The parts, spare boards, etc. are out there if you look.

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.

You are having another problem with the power board...there are some capacitors which are easily replaced to cave you the cost of the board. If you are technical,I can guide you further,other wise a reputable shop can fix this very reasonably

had a very similar situation with my Phillips 42 in. LCD TV.
Here was my Problem. The Power Supply Board. I opened it up( Warranty was Expired) and found several faulty capacitors on the PSB. Its pretty common. Major Electronic companies were sold faulty capacitors that fail in 2-5 years instead of 10-20 due to a lack of preservatives. It wouldn't surprise me if you have the same problem. TV will work fine for a few years and then just fail completely or slowly deteriorate.
Here are the solutions
1. Have it Repaired
2. Check for faulty caps and if you find some(budged or leaking) you know you have located a problem
Remove the board and replace the whole thing.
3. If you have some soldering skills you can replace the faulty caps.
Caps are very inexpensive, under a dollar in most cases. I replaced 4 for about $5.00
Hope this Helps.
