Its been off for about an hour?
First, the red LED on the left comes on when you turn off the TV.... it's a "Standby" indicator. It goes out when you turn the TV on.
So try it again. Unplug the power cord for a few minutes and all LEDs will go out, then plug it back in. The red LED on the left should go on indicating it's in Standby, but not turned on yet.
Try to turn it on with the Samsung remote control and make sure the red LED on the left goes out, then you know it's "on". If you can't get it to go out, maybe your remote isn't working, change the batteries. If that doesn't work, try to turn on the TV with the Power On button on the right side of the TV bezel. Check the manual to see where it is, or I can look it up tomorrow... I never use it so don't know offhand.
If the Standby red LED on the left goes out, then the TV is indeed turned on. Hit the menu button to see if you can get a menu up on the screen. That will prove the screen itself works.
If you can get a menu or anything up on the screen, then make sure your HDMI or component cables are plugged in firmly and try to watch something.
What do you have hooked up to the TV? If you are only trying a cablebox, and you have a DVD player or blu ray, try one of them to see if anything comes up.
