Those 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.

Have you checked the outlet to see if it has power?? If not, check the circuit breaker for the outlet. Otherwise make sure all the connections on the P/S board are correct and that they are all connected.

Chances are if it briefly comes on the backlights I mean the power board is shutting off because of over voltage or over current and some lamps are bad...On this set of yours if you try to test the strips you need to take into consideration these are 6 volt lamps not 3 volt that are used on most sets.

There is a circuit board going bad on it. You can get more detailed info on you tube. Just list your tv model and number and it will show you related videos.

Make certain that your WIFI settings have not changed. Had same problem once, re-entered WIFI information and it worked.

If you have backlights its not going to be the tcon for future reference. you have some shorted or open LEDs in the panel. Check the voltage going to the LED sets, should be 100 plus volts
