Question about Vizio E422AR - 42" Class 42" viewable LCD TV

Open Question

Turns on then back off again

Vizio logo comes on the screen when power is turned on. The logo says for a few seconds 5-6 then the tv turns off again. This happened once the day before, but came back on after a few tries. When it came back on that time a notice popped up that said firmware update complete. Not sure if that would have anything to do with it but thought i would mention it.

SOURCE: Power is there, but TV won't turn on

stored voltages are high no touching these circuts becuase they hold charges and alot of screws.
fualty capacitors you say after a while it stays on theres a full charge in the unit theres some type of discharging effect on the set after its off for a while. voltage goes to low or unstable after it is off for a while. your better off getting the service docs for this set if you want to diy..other wise get a tv tech to check it for you. hope this helps

SOURCE: Hey there, I have a 6 month old vizio 32" LCD 60hz

Most probably the mainboard of the TV has a problem. But no worries as it is only 6 months old call up Vizio and they'll replace it for you free of charge :)

Vizio model M320SR has black screen but has sound. V logo appears when tv is first turned on then goes away.


If there is no video but you have audio or you have intermittent video:
  1. Press and hold the mute button on the VIZIO remote for 3 to 5 seconds. Some VIZIO TV's have a "Mute Screen" feature that turns the screen off if you are streaming an audio application (Pandora, Spotify, etc) and don't want the screen on. To activate/deactivate this feature, hold the mute button for 3-5 seconds.
  2. Turn the TV off and unplug it. Press the power button on the side of the TV for 30 seconds. Let go of the power button and plug the TV back in.
  3. Check the connections between the TV and device. Ensure the cord is connected securely to the TV and the source device.
  4. Try a second device. (Example: If the issue happens on a Cable/Satellite box, try using a DVD player or gaming system to see if the issue occurs there.)
    1. If the issue occurs on multiple devices there is an issue with your TV. Please contact Support by Clicking Contact at the bottom of the page or give us a call Monday - Friday from 7am - 11pm Central Time or Sat. & Sun. from 9am to 6pm Central Time at 855-833-3221.
    2. If the issue only occurs on one device the issue is not with the TV but with the device or the cables used to connect it to the TV.

Vizio tv model e420vse turns on and then screen goes black. Still has power and sound. If I turn off and back on, the picture will come back for a few seconds and then shut off again. Vizio suggested it...


There are a lot of references on how to repair the LED backlight. If you can source the parts, google search LED backlight repair.

Vizio e322ar won't turn on


My Vizio E322AR White Vizio Light comes on when plugged in, then slowly fades to "Off". I unplugged and replugged - same. I held down the power botton on the side, and plugged in... same. Vizio light comes on (White) and over 5 seconds or so... fades out to nothing.
Remote doesn't do anything, buttons on the side don't do anything.
Going to pull the back off and look for bad Capacitors, and test fuzes for continuity. Wish me luck ... will report back later with results.

Vizio e322-ar turns on, displays VIA logo, then turns itself back off.


Usually when a TV fails to turn on properly a lamp will flash a number of times which with the correct info guides you in the direction of the fault.

VT420M no sound or picture and turns off by itself


this sounds like a main board failure but a defective power supply can mimic some symptoms of a bad main board. I would recommend you get a diagnosis done on the set. If I was a betting man, I'd guess the main board
