Expert:  Shahid replied 1 year ago.

OK, please remove one flexible cable from t-con board which comes from inside display panel, no matter if it is left or right cable, turn On the TV. Does any change visible on screen?

Customer: replied 1 year ago.
nothing at all
Expert:  Shahid replied 1 year ago.

Sorry to hear that, unfortunately it seems display panel internal failure (internal circuitry of screen isn't working any more) that is why no response at all. I am really sorry about this and you are going to have to return the TV to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you. If TV is out of warranty then screen replacement would cost approx new TV price of same size if replacement screen is available with Vizio Parts. I trust my input will help you out to make decision about this TV repair or invest that money on new replacement TV. Please feel free to respond if you have any additional questions.
