You will need to trouble shoot the start up and shutdown circuits. Often this is a minor component failing causing the set to not power up or go into protective shutdown. Do you have the service manual for this TV?

I HAVE THE SAME PROBLEM ,I FOUND OUT AFTER OBSERVING FOR QUITE SOMETIME THAT THE CLICKING NOISE I HERE AFTER PLUGGING IT TO THE OUTLET CAME FROM A RELAY SWITCH LOCATED ON THE POWER BOARD AFTER TAPPING ON IT THE SET WOULD POWER AND THE BLINKING RED LIGHT GOES TO NORMAL..I BELIEVE THIS RELAY IS CAUSING THIS PROBLEM FOR ALL THE FELLOWS OUT THERE WITH THIS TV SET AND THE BLINKING RED LIGHT..IN MY CASE THE RELAY WENT SO BAD NOW THAT THE COIL THAT MAGNETIZES TO CLOSE THE CIRCUIT GAVE UP ,SO I PULLED THE COVER OF THE RELAY TO UNVEIL THE TWO METAL STRPS THAT COME IN CONTACT AND HAVE BENT ONE SLITELY TO REMANE CLOSE THIS POWERS THE TV UP NORMAL BUT IN ORDER TO SHUT IT DOWN I HAVE TO PULL THE OUTLET. THIS IS TEMPORARY UNTIL I CAN FIND WHERE TO GET RELAY SWITCH. PLEASE DONT TAKE MY RESEARCH AS A SOLUTION BUT FOR WHAT EVER ITS WORTH. I WILL GET THIS UP AND RUNNING AGAIN ITS ALL WORTH EVERY DOLLAR TO FIX.

Most likely a power supply failure although the flashing of the LED a fixed number of times may point to something else such as a lamp failure. If you can find a forum for this series, you may find a Panasonic tech who can give you a better read on this.
