You can't get into settings with a remote. All televisions HAVE to have a remote. Basic functions only, on off, volume and channel change.

It's probably "setup" then "channels" then "auto scan".

Try , vizparts, or ebay

it is very likly you have problem with the buffer boards, sometime help to unplug conector and reconect, also check the smd fuse located on one of the boards since there are 2 buffer E&F.

Get a professional diagnoses on the set. My first guess would be a defective main board but issue could be power supply related as well.

Check this site for more details. "Electro-help" is the site name. Search it by google search. You can locate it, either at the bottom of the first search page, or at the top of the second. It is an electronics equipments repair help site in English.

The tv is having a problems with the board called T-Con board it is dying and the problems.That why the tv is not sustancening the tv pictures for those coded pictures pixels by the T-Con board to stay on to the tv LCD screen panel.This tv problems only causes by the tv T-Con board it is dying only if the tv problems came on to the tv by itself only.If these problems causes by u or an object by outer forces by hitting to the tv LCD screen panel itself.Now the tv LCD screen panel itself it is dying and the causes.Than the tv it is not repairable,tv now only can it to do a replacement of the tv whole LCD screen panel itself only.Not practical because the tv LCD screen panel are 90% important to the tv and the cost of the tv.If u replacing the tv LCD screen panel itself will cost the same as a new tv.The tv is under a year old,why don't u just call Vizio corp. and take ur tv warrenty repair.
