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.

It sounds as if the power supply is depleting as you draw more power I would replace it first

Hi I have Vizio e422va it's not turn on only front power light is on white when I plug power coward no led no screen is black please help

When the TV does this, the RED LED on the front will blink. For digits 1-10 it will blink pause then repeat. For numbers with 2 digits it will blink the first digit slow and then second digit fast. So 25 would be 2 slow blinks followed by 5 fast blinks.
