Thank you for your question, my name is ***** ***** I look forward to assisting you.

Please note, a rating is only needed when we are finished.

Can you please remove the power to the TV (so unplug it from the power socket).

Then on the actual TV, hold the power button for 60 seconds then release.

Then wait 10 minutes, connect the power again to the TV, turn it on and tell me please if it is now operating correctly.

Let me know the results please

Didn't help. Vizio logo flashes, back light comes on, menu won't come on the screen.

Disconnect everything from the TV, all HDMI connections ect

Then connect only the power, power it on and tell me if you can get the menu to come up please.

Customer: replied 10 months ago.
Nope, no menu, nothing but the back light.
Expert:  Richard replied 10 months ago.

ok, shine a flashlight at the screen at a 45 degree angle. Do you then see the picture faintly?

It is the internal TCon board or mainboard that has faulted.

I am really sorry about this and you are going to have to return the TV to have them test and confirmed and replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.

I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.

And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.

Thank you
