Vizio E421VO -... | Answered on Jun 05, 2016

There are several ways to change your video input source for the E421VO. First: the lowest button on the side of the TV will cycle through the inputs. (The power button is the top button.) The original remote has the Input button to the left of the Zero button at the bottom left of the number area. With both just press the key multiple times to go through all of the inputs. Alternatively, press the Menu button and look for the Source sub-menu. Use the arrow keys to move to the chosen menu. (On the TV, the menu button is below the power button. On the remote, Menu is the button to the top right above the arrow keys.) If you are using a universal remote, you may need to find one that matches the Input or Menu functions for your TV. A different code may help if the remote has either button. Otherwise, you'll need a different remote.

The manual for the Vizio E421VO is available from Vizio's product site: http://www.vizio.com/e421vo.html . Click on the Support/Manuals tab. The direct link to the manual is http://www.vizio.com/documents/downloads/hdtv/E421VO/UM_E421VO.pdf . All of these options are shown in the manual.

I hope this helps.

Vizio doesn't support phone connect - only USB drive (ie thumbdrive type) - With correct USB, TV will show USB as a 'Source' - and if selected will show the files on the USB, but can only open / view folders, images, and video types.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

3 choices,
1-sell it. broken( cut losses)
2-buy the service manual and read the tests there and rules for swapping parts not allowed, willynilly.
3-last guess and go broke.

Vizio E Series TV?
5 years old is it or older./
no model stated at all just this, why leave out key fact 1.?
no symptoms, my guess TV is dead, no sound and not smart screens, at all, dead, and LED glowing for standby GLOWing.
that is it ?
first off there is no need to have a TV box at all, zero need.
the TV has smart screen and do stream video off say neflix,
NO TV boxes needed at all just internet.
nor do you need anything at all to use the SMART screen.
it will show all streaming choices at any time, just AC line cord attached and nothing else.

lets to POWER Supplies 101 class now.
that is JOB 1. not run any TV.
E28 to E75 TV, hummmmmmmmm NO TV even told.
I guess you got ebay bad used cards? PCB cards?
lots are. for sure. used. and if you USA and card not , FAIL !
some TV need hard reset, ever do that, power cord pulled for 1hr.
the hold power button at same time and plug in power cord?
rear power button E32? see that>? works when remote is dead.

but really all this is in the service manual these steps and rules.
TVs are not all the same, ok?> in this regard.

2017 lawsuit to them for spying on customers. TV to them. oops.
avoid them, no?
they do have the cheapest TV made award $159? (this?)_

The E= economy brand, ?

Some are known for dead LED back lamp,power packs or even the LED lamp string dead. known.!!! cheap made parts fail here.
so if screen is dead, and a hard reset fails use the service manual
click page called trouble shooting and click dead screen.
and proceed from there, per the manual first.
the cure is LG, buy LG and win, no kidding.
As you can see TV turns on just like a PC.
the 5vStandy dead,means the logic board can not respond the power on button the power on button is A digital command.
so if standby is dead or noisy,(cap) TV will never ever turn on.
This unlike any TV from 1980 and simple, not it is a computer inside and a OS running to make the smart screen work.(desktop like)

video class:
$10 meter work too, ever word below true, but I can add
lots more can fail there, not just that EEPROM chip. LOTS.
