My Samsung LNT4665F 46" LCD TV has great... for 2 years (made 6/2007, died 8/2009). It appears the power supply has died, something I've seen reported by others online. Symptom: it appears to be trying to turn-on, over and over again. No picture or sound, other than "click" each time it restars the power-on sequence. All I can see now is the red blinking power LED.
