"It's referred to as 'flashlighting'. It's a common problem in LCD/led as the driving factor is lighting pushed through pixels to create the picture. What you are seeing is a spot where the lighting is passing through unscathed or overpowering around the edges since this is an edge lit tv.
Some TVs are worse than others even if they are the same model, size and even batch.
This can be caused by many reasons... You have 2 options, return and/or exchange it at your local store if still in that window. Or you can call the tv manufacturer to see if it is out of their allowable tolerance levels.
Remember some flashlighting is still within their specs so even though you may not be happy with it the manufacturer may not fix it.
Many people find some relief by turning brightness down, contrast down and some TVs allow you to adjust back light levels. If this one does then make sure it is not on high.
For more info on this I would go to hidefjunkies.com as it has tons of great info."...Also,"take it off Dynamic mode is the first step. Then put it on something like Standard or Movie. This will not fix it permanently, but will give you a better experience." (I hope this answers your question...if it was ME,I would take th darn thing back,if still within warranty period.)
Unplug set and hold and press the power button for about a minute. Replug set and turn it on. If nada, then the issue is with the power supply of the set. Given its age and the high cost of repairs it might be more cost effective to get a new set.
Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Hi Evan
Essentially it's a computer inside a modern Flat Screen TV these days. Not a lot that the average person can do...
But... if you feel capable of opening the back....
Once you get inside and check for loose or poor connectors,
I would be looking for leaky Electrolytic Capacitors.
Usually in the power supply section.
Look for brown fluid leaks on PCB & a very slightly puffed out or bowed top on the cap. (ready to explode)
Take a picture of suspect. Take note of Polarity (black stripe) & write down uf & voltage & temp values.
eg 1000uF @ 25v
To prove you are on the right track, you can connect a similar rated Cap across (in parallel) the existing Cap.
Depending on space etc. Even by short extension wires.
Power up & see results. Fault Gone or Not?
Then...
Unsolder & Remove suspect Cap & try to replace with higher voltage rating & slightly higher uf capacity depending on space available around the components.
Good Luck

Some service manuals are hard to get. It is sometimes best to contact the manufacture of the device to request one. You can call them and see if you can request one.

It looks like the control board is not receiving a voltage that it is expecting to tell it the TV is fully on, and is going into a fail-safe shutdown mode. I would start by looking for swollen capacitors on the boards in the set as well as for loose/bad solder connections on those boards. Aside from that you would need a service manual and some test equipment to troubleshoot it. Sorry I can't be more help, I have not had to work on this particular model before.
Change the aspect ratio.this can usually be done via the remote or through the tv menu.normal view for most wide screens is wide 16:9 but if you have zoom or crop black bars then you may lose parts of playback.
Hi
It sounds to me like you have a bad main board.
But it you may be better of by buying new TV
those boards run over $300.00.
You know the prices of a new TV's !!
Good Luck
Vizio have a parts distributor- Vance Baldwin you may give them a call, or call Vizio to find out if they have anybody else.
if your TV is wifi enabled then you just have to look for the networkyour network off your router and then hook it up like you would any other devicethat's wirelessif your TV has an Ethernet port you have to run it hard wired to your routerpersonally I take the password off my wirelessbecause it's easier to connect devices to itotherwise press the WPS button on your router should allow you to connect without entering passwordbut you do have to have a broadband connection DSL or cable and you have to have a router
To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; check the site linked here.

http://electronicshelponline.blogspot.com/It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.
