Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/ In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

SOURCE: why does my vizio lcd

Good day!

Please follow this procedure to fix your problem:

  1. Open the cover of your TV.Remove all screws at the back.
  2. Next,power ON the TV and check the output voltage of power supply using voltmeter.
  3. It should have not less than 5vdc for system board,12vdc for sounds and 24vdc for inverter board.If the 3 supplies are got a voltage drop your power supply had problem.For example if you check the 5vdc then the reading is 4.50vdc only.
  4. If you have voltage drop,check some leak/bulge on top capacitor on power supply.replace it by using soldering iron and soldering pump.
  5. When the power supply looks like OK,no voltage drop and no leak/bulge on top capacitor.The problem is your system board or main board.There's no easy remedy for that.You have to replace the whole system board.
I hope this solution helps you to fix your problem.Thank you and good luck.

The resolution for TV's is auto sensed by the content being sent to it.
If you are playing a 720p file, you cannot make it 1080p. 720p vs 1080p Can You Tell The Difference Between HDTV Resolutions

Probably you have a problem in the power supply board .
Vizio lcd or led always has a problem in the standby circuit of the power supply .

My Vizio E550i-B2 nothing happens when turned on,, Replaced power board today but it did not fix it?


Vizio are known problem TV set. Before you do anything else contact Jimmys tv online. They have all kinds of tech help. If you have a knowledgeable person about electronics they can help determine which board is bad. Look for swollen caps, burnt parts, may help determine the board. But also look for a service manual online, helped me a lot.

I have a Vizio D650I-B2 tv and will not turn on what so ever and I need help getting the back panel off.


The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. 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. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

Please use your remote to access the video portion of the setup screen. You should find a reset video to factory defaults there or in the initial setup portion. Your manual should point you to the proper section to find these.

Tv won't turn on


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:


UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

if it is 2,2 I have start to finish instructions for this repair in this model.
