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.

I have the same set, and same problem.
After many hours/days of reading about this issue (which seems to be a popular one for this series and others) I have found a few sites that have detailed info on what can be done.
This link is for a different set but the same issue.

This problem seems rampant on many Sony sets. There really should be a class action suite against them for the replacement cost of the parts which can be $400(USD) or more unless you are handy with a soldering iron.
I have a service tech coming by to look at the set soon ($75) so he can tell me what is actuall wrong with it. Once I know if it is the D-board or the usual 3 ICs that die. I will most likely have a friend of mine solder on some sockets to replace the ICs if the happen to die again.
Good luck
