Vizio TV model E550i-B2 shut off with a click sound. No picture, audio or display light. Will not turn back on. Any idea what may need to be replaced?

SOURCE: I have a Vizio E550i-b2 55 LED TV. I have no LED backlight. When I hold a flashlight to the screen I can see the images and I have sound. I was going to replace the LED driver? Thoughts??

Hi Jimmy,
If I may suggest, before changing, please check that the inverter board is producing the necessary voltage to drive the backlights or not. If the board is producing the necessary power and still the backlight is not coming on, there is possibility that some of the LEDs in the backlight array have failed.

Testimonial: "No matter which HDMI input I use the screen is totally black again. The apple tv works fine on a different Vizio TV with a different HDMI cable."

SOURCE: 55 Vizio LED e550i-b2. Confirmed no back lights. Unplug for few hours, replug and works again for a few days. Is best bet led invertor going out? Visually the boards and connections look ok.

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.

To 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. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

The main board of the tv is faulty. Can be a hardware fault or software error. You have to replace the mother board or can consult the service center.

SOURCE: I have a Vizio E550i-52 tv and the screen went black. I have audio, I see no light from the back and when I do the flashlight test I see a faint picture. How to fix?

Hey Matt, It was nice speaking with you on 6YA. If I can be of anymore help feel free to ask. Several other forums I browsed recommend replacing both the LED Driver and the Power Board at the same time and several say one at a time is fine. Replace the LED Driver board then go from there.
