Minium is the green picture tube need to be replaced, if you can take the front cover and access panel off there is a control with 3 focus and screen controls.
you can adjust the 3 screen controls to possibly get a little more time out of it before the crt's need to be replaced. careful if you turn them down too much there will be no picture, and if you turn them too high the tv will go bright and shut off

Vizio tv repair picture blurs and darkens for five seconds and then goes normal for five seconds and continues this cycle. i changed the tcon board and no change.


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Wont turn on. on light comes on for 5 seconds then shuts off


Do the self check this model has.

When power light goes off on the front of the set press and hold both the menu and input (device) at the same time and hold for at least five seconds and release both buttons.

The power light will blink a two digit error code: like 2 blinks, 2 blinks, a pause and then repeat it several times.

Let me know by leaving a comment here what code you find and I will tell you what it means.

When the TV is powered up, it shuts off in two to five seconds.


DO THIS: when set comes on and goes off (green power light) On the front of the set press and hold BOTH THE MENU AND INPUT BUTTONS IN TOGETHER FOR AT LEAST 5 SECONDS AND RELEASE BOTH BUTTONS.

Power light should blink a two digit error code like 2,2, a pause and repeat it up to a total of five times.

Let me know what error code and I will tell you what it means.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

My model is a WS-55511. I turn on the TV, the

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

There are some capacitors on the power/HV deflection board that usually blow. You can actually see that they have vented on the top. Cp150 is the most common to go.
