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....

Good morning. I have a Vizio e550i-b2 with no picture or sound but I did the flashlight test and I can see picture. Any idea what I need to fix my issue. thank you so much

This model develops bad solder joints on the connector between the power supply and the led driver board and loses backlighting. It's hard to believe, but the whole connection goes bad. All those pins supply only 24v and gnd. Resolder all of them and the tv will work.
It's the connector between that large yellow board (p/s) and the center green board (led driver).

I'm trouble shooting my Vizio e550i-2b It has power no backlights, image can be seen with a flashlight, I've replaced led driver board and problem persists, do you suggest main board next?

If you can see an image with a flashlight and you can control the tv with the remote then the main board is not the problem. You've replaced the LED driver board, so that leaves the LED strips inside the LCD panel as the likely problem.

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.

Backlight for tv

One or more of the LED backlight strips behind the LCD have failed. Difficult and sometimes expensive to fix.

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??

U are on the right track - problem is caused by the board that drives the backlighting - the inverter board.

If you can get the number for the board it may be available on the cheap on ebay.

You need to perform the flashlight test. Turn off the lights in the room, turn the TV on, take a bright flashlight and shine it on the screen. Do you see the faint image on the screen?? You could have a defective backlight inverter, defective power supply, or a main board issue. You set will require diagnosis to determine.

Picture went out on p50hdm Vizio Plazma tv after loud POP

It's either the backlight lamp or backlight inverter is busted due to a power failure or fluctuation. Here's how to determine which is which:
  1. Grab a flashlight.
  2. Turn on the TV.
  3. Shine the flashlight onto the screen.
  4. If you cannot see any display even a faint one, the backlight inverter is dead, else the backlight lamps are busted.
  5. Replace which ever is the culprit.
