pchrist2,
It may be your power supply isn't working properly. I would definitely recommend getting the unit serviced.

I have had this TV for 1.5 years. Recently this started: when I first turn it on it makes a double "click" sound and the red light flashes 5 times. Between the second and third flash the startup sound is heard. The next three times I turn it on it does the same thing. On the fifth try it turns on. Anyone know what is causing this problem? Thanks.
