Is the power cord firmly inserted in the back of the television?
Have you tried different plugs in the power strip?
I have the Samsung FP-T5084 50" Plasma tv. I went to turn it on the other day, and it wouldn't turn on. No clicking. No red power indicator light. Nothing. It was plugged into a power strip with other components, and they all work fine. I unplugged it for a while and then plugged it into a different outlet on the power bar, but it still won't turn on.
