Question about Vizio 39" E390VL 1080p LCD HDTV

Open Question

At certain times, the pitch of a voice on my new 39" Vizio will cause a humming sound. This is intermittent. Adjusting volume up or down can mitigate it somewhat. It's like it happens at certain pitch or volumes. It's new so I can take it back. But is there something I can do to adjust it?

SOURCE: Vizio Volume Control

I am sure you did this but recheck your audio menu on all your inputs. I have found that cables can go bad so make sure they are in good shape. Are you haveing the problems with all your inputs dvd, cable (direct cable or a cable box) whatever? It is hard to affect the audio by just moving the set. I am hoping that you changed something or the cables went bad that would be the easy solution.

Good Luck!

SOURCE: My Vizio Tv volume does not work properly. When

Okay I just called and found this out. I have the 32 inch vizio hd flat screen. My problem with weak and fluctuating volume, was that I have a cable box. Go into menu, then audio and under the advanced audio section you will see srs trusurround HD and srs trusurround. Basically this function automatically adjusts volume levels for satelites and whatnot. But because cable boxes automatically have this feature you could just turn off the srs trusurround. Hopefully that should help you.

we have had the same problem and I suggested to Hubby that we had better return it soon. He did some research and we are trying this: use the TV remote and press the center button "Select", Choose Audio, Make sure True Volume is set to On. I've only been watching for an hour but it very well may have solved the problem. Hope it works.

SOURCE: We replaced the IR sensor on our Vizio but still cannot control the volume via the remote (which has tested good). Any further suggestions?

Since sensor is receiving the signal of other inputs, there is nothing wrong with it. This looks like an incompatibility issue. You may have to retry using the original remote control.

Not at all in this case. You either have a loose wire to connections to the cartridge, which can be fixed by hand. Just push the wires on to the cartridge. Or you have a fault in the power supply of the deck. Most likely a mains filter capacitor that is letting the 50hz mains hum in.

The hum will either be caused by a poor earth connection or a power supply problem. The stylus would not cause any hum at all.

I had this problem with my previous TV (Syntax by Olevia, an off brand). It only happened to me on certain channels, and for certain shows. What is happening is the TV station is broadcasting the audio in Dolby 5.1 format. For some stupid reason, the TV is playing the background speakers (effects) instead of the speaking parts. You get a little bleed-over of the voices into the back speakers, so voices are there but really quiet. Unfortunately my TV didn't have any surround sound options to fix this.

See if your TV has a surround sound option. Otherwise, you will need to connect the TV sound output to a surround sound system that can properly decode the audio channels.

If you can handle it then check the 12VDC supply filtration. I mean to say that you have to confirm that the 12VDC is coming with stability and no noise inside it. The filtration work is being performed by the capacitors in the circuitry. Check the capacitor condition in main board please. If it is plague (bad capacitor) then try by replacing it. The sound can be mainly heard through speakers and it most probably caused by sound processing area presents in main board. This kind of thing can be eliminated by changing the main board.

good luck

Hum from tv


try unplugging any equipment that you have attached to the tv one at a time, such as dvd players, surround sound, cable box, etc. also if you have a cable box attached, try adjusting the volume on it. if you have everything unplugged from tv and it still hums, then it may be a tv issue

I have a Vizio 42' and a cable box and there's a constant humming


I think I had the same problem. This is how I fixed it.

I have my vizio 42 hooked up to a Harmon Kardon surround sound, and the digital cable box. Essentially, I can adjust the volume 3 ways - through the tv, cable box or av receiver. The humming sound happens when you have the volume maxed out on the av receiver and not the cable box.

For example, the sound level on my Harmon Kardon goes from -10 (lowest) to 10 (loudest), with 0 being the middle ground. The buzzing was happening when the Harmon Kardon was set to 10, and I was using the cable box volume to adjust the sound. To fix it, I turned down the volume on my receiver to 0, which may be about 50% max volume of the receiver. Then, I switched devices and used the volume on my cable box. This got rid of the static I was getting. Hope that helps.
