You TV need some capacitors changed on the power supply. I have a tutorial on this repair published in my Tips & Tricks. You can save about $170 by doing this yourself, it's fairly simple if you can use a screw driver and a soldering iron. I hope this was helpful.

There are a number of Capacitors on the IP/Power supply bd and they have gone bad. Replaced them with the proper Capacitance as the old ones are BUT get the 35 volt Caps. Going from 10v to 35v will fix this problem.

Call Samung customer service, they are doing this repair for free. I had the same problem at 11 months, they replaced the power supply board under warranty. At 2 years I had the exact same problem again and this time they replaced 2 - 50 cent capacitors on the power supply board. It took the repair man less than an hour and he had the replacement capacitors on hand. The original board and the replacement board they gave me had capacitors that were faulty. Hopefully these new capacitors will last. I have to say that I was thinking (no more samsung products for me) but I got excellent customer service and they admit that they had a faulty product and they accepted responsibility.
