thomasj1946,
Sorry to hear you're having issues with your television.
Assuming you don't have an extended warranty, you might try registering your unit online. By doing so, you gain an additional 3 months of warranty from the original purchase date if purchased from an authorized Samsung dealer and not refurbished. That way, after you're done registering, you can call 800-SAMSUNG and have a tech take a look at your television and get the issue fixed.
Keep me posted.

My LTN5271 started this about a week ago. When turning it on, first thing in the morning, it would clicking on and off 4 or 5 times before finally turning on. After that is was perfect for the rest of the day. It stays on all day and is not turned off til night but turning on the next morning, the same thing happens. It was purchased 14 months ago.
