This is actually(And Sadly) an extremely common problem with the Vieras. The number of times it blinks is a fault code. 7 and 10 blinks are typically board failures inside of the unit usually being the power supply. It can be other things like a clogged fan freaking it out etc. If you search google you will see many cases of this problem and what each # of blinking lights indicates.
Things you can try at home are:
Unplug the unit for 20ish minutes. Sometimes this brings it back.
Did you install something else on the circuit? If you put for example a window air conditioner in place or something that is drawing alot of power it will not let the TV itself have enough power to run.
Sometimes if you are handy and have some soldering skill and skill using a multimeter you can check the capacitors and other components in the rectifying and filtering stages of the power board and replace them if they are bad for cheap. Capacitors would be the easy one to spot because they swell and look terrible when they go out. DON'T DO THIS IF YOU DON'T KNOW HOW TO WORK ON ELECTRONICS. OR DON'T FEEL COMFORTABLE. THERE ARE SOME DANGERS INVOLVED.
Otherwise if you have 7 or 10 blinks at a time it will need service.

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/
Blinking codes details to many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.
