I have a vizio E321VL its an LCD and recently the screen went black. When I turn it on the vizio logo comes up and backlights come on but then screen goes black. Ive tried changing input or changing channel but nothing comes up. All buttons and functions work its just the screen. I want to say its the backlight but why woukd they come on with the vizio logo at first? Ive had this TV for less than a year.


Vizio had problems with the processor boards.
If you had no lights, I would say power supply, Logo with lights, I would go with Processor board, check ebay. It is called a main board and they run about $60. That is what I would get, but then again, how old is it? If I could replace it with a new for $250 why take a chance for $60. I have pitched them before.http://www.ebay.com/sch/i.html?_odkw=E321VL+main+board&_osacat=0&_from=R40&_trksid=p2045573.m570.l1313.TR2.TRC1.A0.XE321VL+main+board+refurbished&_nkw=E321VL+main+board+refurbished&_sacat=0
You tube also have videos if you are a electronics repair person.

Audio works but not the video.


the thing about these consumer tv's is that they use the most grossly cheap electronic components in them so that they wear out quickly. the main power board is faulty, could e several small capacitors or a transformer , but a electronics service tech will need to do the work unless you have used a soldering iron and are comfortable with it. A replacement power board may be found on ebay for your model tv.
and last purchase a backup power supply to condition the electricity so that the tv will get smooth electricity from now on. hope this helps you . good day

No display


If it boots with no video, then it is a bad built-in video controller. If you get a long beep then its the processor.
