Thank you for clarifying.
Since it happens on the menu too, that confirms it is an internal fault, meaning a bad lcd panel, tcon board, or main board.
There is one step you can take here, both as a possible fix, as well as a diagnostic evaluation:
1) Unplug the power cord from the outlet
2) Wait at least 1 hour (60+ Minutes)
3) Press and hold the power button (on the set, not the remote) for 60 seconds
4) Keep holding power button while plugging back in, and for another 60 seconds after. When plugging back in, go directly to the wall outlet, bypassing any power strips or surge protectors.
If this reset process does not work, it would unfortunately confirm an internal hardware failure. At that point your best recourse is to return it to the store for a refund/exchange.
If they will let you get a refund, I'd highly recommend getting a different brand/model, and I can recommend some for you if you'd like. This type of hardware failure is common with vizio tvs, and in general they are very poor quality and short lived, we don't expect to see these vizio sets last more than a few years at most, so even though you save a little bit on the cost, you'd be better off spending a little bit more for a more reputable brand that will last much longer and be better quality.
