Power supply regulator board fault. These blinks [flashes] are fault indication. You can get an idea about the faulty stage circuit inside the TV, by the number of these blinks. Count it carefully, by switching it ON and OFF, more than 2 times at least, so that, you can make sure about the number of these blinks. If you wish to get more details, check the site linked here. Surf the site in "MOSAIC" view.

B+ over voltage protection (OVP), unit goes to the standby mode then
displays the 3 blink fault. This is also a problem in the power
supply circuit, check T603 and R672.
Have you set the output voltage correctly?
