Loud pop and now Vizio 37 TV will not work

Tv was working fine then when I went to turn it on with the remote there was a loud pop and now the TV will not come on. I hooked another TV up to be sure the power surge protector works and it does. Would like to know if the TV is fixable.

This sound like the power supply board went bad. You should check that. See if the fuse on the board is blown first.. You can get a "pulled" power supply board on the net if needed.

My vizio 42 inch just made a very loud pop and the screen went black (off), the vizio leters at the below the screen stayed lit white as if the tv was still on. 5 minutes later a very loud pop then came...


Is it possible that it was storming when this happened? It could have been a power surge. If you are still covered under the manufacturers warranty, you should give them a call. Even if you aren't covered it wouldn't hurt to call to see if they can help or offer a discount to have it checked out and/or fixed.

VW37L 37 in. LCD HDTV input button wont work


Have you find out if the problem is with your remote control? For instance, you are able to control your TV using a Universal remote control. My 32" Vizio TV had a similar problem, initially thought it was related to my remote control but in fact the TV didn't respond either to an universal remote control of my SAT receiver that I eventually use to just turn on and off the TV. I've found out that the problem was with a little board on the TV located at the left down corner viewed from the front side of the TV and that receives the signal from the remote control. I found the board on ebay for about $5, replace it and the TV responded again to both original and universal remotes.

Last night our TV made a loud popping noise then the picture went out. We still have sound but have trouble turning the TV off. What could this be and is it fixable? Thanks, Anne Marie Orcutt


Hi,
Question shows it is Vizio L32 lcd tv and symptom shows back light inverter board for defective for some reason and loud noise would be popping of any chip on inverter board.
Shopjimmy..com has replacement boards of that model on reasonable price and local tv repairman will replace defective board after checking/ testing the tv.
Hope these info will help.
Thanks.

No picutre just black-loud pop when I turned it on


You may have blown parts, look inside and inspect the power supply module and the back light inverter board, I will leave the TV unplugged.

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.

LOUD BUZZING/HUMMING SOUND- CAN HEAR OVER AUDIO


have someone check speaker ground to the TV chassis. Your speakers are picking up reverb from the Video Signal.

Had loud pop and then no picture on the vizio 50in. plasma


TV was on with no picture problem. Left the room and when I returned the picture was very dim. Turned system off and turned back on. Picture didn't change, but heard a loud pop from the back of the TV.

Hello SuziCanevaro,

This may have been the sound of electrolytic capacitors exploding. I would not suggest plugging the set back in until you can have it checked by a qualified TV technician. If you are skilled in Electronics and would like to work on this yourself, you will need:

The schematic diagram, a multimeter, a signal generator, an oscilloscope, and an isolation transformer.

I hope this helps,

Thank you,
