Your TV mainboard is damaged and need to be replaced, the price should be around $80-190 and you can do it yourself.

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.

I got the same TV for my stepdaughter and had the same problem. None of the Emerson codes worked. We use Dish Network but I did the autoscan thing on the remote and found that it was 672 which is listed as a Sylvania. I don't know if it will help in your case but maybe try the Sylvania codes. Good luck.

Y Sustainer problem. However, normally they have to change both Y Sus and Z Sus boards at the same time. If you lucky than it's just a fuse on the Y sustainer blown (the chance is very rare) otherwise the IPM (Intelligence Power Module) on the Y/X sustainer board is short. more then likely if you can get the IPM off of the board you will see that the components are shot, that is the popping noise you heard. shopjimmy.com has these boards some are cheap some are not...good luck

I had the same thing just happen and I used the following instructions from the Vizio Website for "humming sound" on tv and it worked. My sound is now working!!!!

1- Power off TV

2- Unplug TV from outlet

3- Press and hold in the power button on the TV for 30 seconds (while it is unplugged from the wall)

4- Release the power button

5- Plug in the TV into a different outlet

6- Power the TV back on.

Reset the TV settings.
