It's pretty difficult to diagnose the television without actually being able to look at it. However, if you register online, you may qualify for an additional three months of warranty, meaning no out of pocket expense for you if it's approved.
After registering, call 800-SAMSUNG and explain the situation, and see if they can get that done for you.
Hello All. I purchased my LN40A650 TV set in April 2008 and I'm now experiencing my first ever issue with it. Starting yesterday, the TV picture will freeze, I'll hear a buzzing sound over the speakers, and then it will try to reboot. The issue continuously cycles. I've definitely confirmed it is a problem with the TV and not any of the sources. In fact, with no signal source attached, it will search endlessly with no issue, but the moment I attach a cable from any source, the problem starts. I'd greatly appreciate any advice you can provide as I'm currently unemployed and doubt I can afford any tech service
