Im not an expert by any stretch i have a vizio with the same issue and I have also replaced the powersupply / dc inverter board. I suspect we both need new mainboards. A site named shopjimmy offers many replacement parts at good rates. I am in the process or replacing the Tcon and LED driver boards now (they are much cheaper than the main) if either of those corrects the issue ill post a comment. FYI My problem on the Vizio TV was corrected by replacing the main-board after all.
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.
you will need to replace the leaky capacitors in the power supply circuit. You can locate the faulty capacitors with a visual check. Those that are bulging need to be replaced.
