Aug 26, 2015 - Vizio TV power cord plugging into a power outlet. Do you know ... Powerproblems might require service or replacing parts inside the TV. Before ...

the first thing i would do id completely disconnect power to vizio tv and wait roughly two mins before plugging it back it. once that is done try to see if your picture comes back up . if your screen does not comes back the tv has unfortunately taken a turn for the worst. sometimes it costs more to repair than it does to replace so just make sure that your tv is or is not covered under a manufacturers warranty that may be able to have to tv replace for free depending on the scenario. below is the number and hours of operation. i also gave you a link to their support site. good luck!

Many Visio tv's have the same problem, and also reversed - picture and no sound. The quick fix is to disconnect the power cord at TV - then hold in the power button (usually found on left side 1/4 up from bottom of screen , located on the side/back of the set. a square button all alone) - hold power button in for 30 1,000 mississippi's, yes, that is what a Visio tech told me and it works. I was lucky enough to have the problem start before the 30 return policy ended at Walmart - decided I did not want a product that obviously has a chip failure coming soon! I exchanged for a Samsung and have not looked back!

Defective LED back lights strips, or damaged EEPROM on main board. I will try a main board first, if you do nor have a TV LED strip tester.

I will try a new main board first.

Sounds like you had a high voltage power surge just before going out
Are u using a high grade reference center or surge stage 2 or 3?

if you have comcast you can use your remote to change the tV program from cabke to DVD then change it back to cable. your image should come back.

why should i tell you (fixYa) how i fixed the problem for free? You wanted to charge me for your info so i think it's only fair that i charge you for mines. I did figure out and solved the problem.

sound like the inverter circuit board problem. check & replace back same part# inverter circuit board. hopefully could help!!

also check the power cord wire coming from the back of the tv is loose from the tv side or perfect.
