[email protected]/Casenumber/2540322 This vizio TV was working on Friday morning. Friday afternoon it had neight sound or picture on the screen. I called the company and they gave me the above case number and said some one would come out to fix it. I have heard nothing since friday and this is Monday evening.

SOURCE: Picture but no sound on my Vizio L37 Flat Screen

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.

SOURCE: my vizio P42 went "pop" black screen with sound, any ideas?

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

SOURCE: Vizio L32 32 in. HDTV LCD HDMI input not working

I recently had the same problem with my vizeo hdmi port # 1 going bad. Tried everything to fix and called vizeo. There solution for a master reset was turn off tv and unplug from the wall. then hold down the power button for 30 secs and let go. plug the tv back in and hold down the volume down and input select buttons down on side of the tv for 15 secs. release the buttons and turn the tv on after powering down all the components connectd to the tv. If this does not work they told me you need to have it sericed for a bad hdmi input. Hope this info helps anyone out there. It didn't work for me. Its a bummer cause the tv is well taken care of and only 18 months old. Best of luck to all others.
