SOURCE: vizio e550i-b2e has picture but very dark no light illuminating in the back. Has sound. What do I have to replace?

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.

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.

SOURCE: I have a Vizio E550i-B2 and the screen went blank, I do still have sound. I did the flashlight test and I can see the screen very dim. Would this be the LED driver board or power supply board?

Hi,
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 the pins on the power supply half of the connector and the tv will work.
It's the connector between that large yellow board (p/s) and the center green board (led driver).

SOURCE: I have a Vizio 55 inch, Model # E550i-B2E It has no picture but has sound and if I hold a flashlight to it I can see the picture. Do you have any idea what it can be

Your TV has a backlight fault and needs the backlighting either repaired or replaced.

My vizio model E550i-B2E , sn LWZJPPDQ4801123 picture comes on then goes out. What could be the problem and can I repair it myself.

NO you cannot. In some cases, power surges from storms etc. increase the current ratios to excessive amounts and damage the TV's circuit boards. Unless you have Test equipment and the knowledge to trace a circuit for faults, then you cannot fix the TV.

My Vizio LED E55oI B2E tv screen went black. Sound still works.

There are two possible problems maybe three the first one is that TV is known for having this issue if you shine bright light on the TV screen and you can still see a picture but it is dark and un lighted then that indicates that the TV has bad LED or CFL lighting inside the panel this is difficult to fix but it can be done number 2 if the TV has sound but the panel glows if you tap on it in the panel close and you can see that the lights are still on then you know the problem is a defective panel LCD in either case you would most likely need a shop to fix this you won't be able to do it yourself you can watch some videos on YouTube though it show how replace led strips on vizio YouTube

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.
