Blaze777,
You may want to have your unit inspected. It's difficult to pinpoint the cause of malfunctions, but a service technician should be able to give you an idea on how to get the unit repaired. You can find a local shop, or call 800-SAMSUNG for an authorized technician.

My TV is a samsung model number HLS5687WX/XAA that is about 3 yrs old, it just began turning off by itself, I can turn it right back on and it works , but sometimes it will turn itself off again after a few minutes, What could it be and what should I do?
