Question about Vizio SV420M LCD TV

Open Question

The volume on my TV goes up and down by itself. I can't stop it with either the remote or the controls on the TV. Just races up and down back and forth nonstop.

SOURCE: Volume on my TV goes down to zero without me

There maybe another signal coming from somewhere causing the problem. Try blocking the IR sensor in front of the TV. If that stops it, your next step is finding the source.
If blocking the sensor doesn't work, check out the buttons on the TV itself. It may have a sticky or damaged button.
The volume down button may have went bad.

RJW34 I have a 37" Viizio LCD that has a similar problem. I power it up and I get a lit screen but it's blank. No controls work except power on and off.

SOURCE: Vizio 37 inch channels and volume changing on its own

The circuit or integrated circuit being controlled has likely failed. You might try 'resetting' it by pulling the AC plug overnight. If that has no effect, a repair is unavoidable. This model seems to be developing a number of different problems.

Toshiba 32a33. I'll be watching tv and the volume bar shows goes down to 0 (no sound) when it is in this mode the remote control will not work on the volume, you can get up and manually up the volume...


1st check to see if your remote volume down button is stuck. 2nd do you have wireless internet (router) or any other wireless devices phones,ceiling fans, another Toshiba remote, if so try unplugging them (or remove the batteries if it's a remote) while it's changing the volume one at a time. If a different device makes it stop try changing the channel on it. Also make sure the t.v doesn't have a mind of its own and remove the batteries out of the t.v remote, let it ride for a couple days if it happens without the remote being in play then you know your t.v is acting strange, if it stops then starts back up when you start using the remote again then you know your dealing with a remote issue. Sometimes Freq.'s merge causing remotes/wireless devices to conflict with each other.

We are watching tv and the volume just turns itself all the way up. If we turn it down, it goes right back up. It stays like that for about 15 min at a time and then it will allow me to turn it down until...


check the remote control, take the batteries out and try to adjust the volume on the tv set itself.
If this resolves the problem the button on the remote may be sticking, either clear it or get a universal remote.

If you still have the problem without the remote then its time to take the tv to a repair shop or claim on a warranty.

The volume on the TV keeps going down by itself. What should I do?


Dont know what tv you have but. You can remove the batteries from remote and if volume still goes down you ruled out the remote as the problem.. Or just take remote to another room. If the problem still exists then Im guessing either a sticky button on the tv volume down or as I have seen to many times.. People clean their tvs with windex or some cleaner and it drips down into the tv messing up the control buttons. Hopefully its just a sticky button..

Try taking the batteries out of the remote or taking it out of range from the tv. Then try turning the volume up on the Tv manually. If the volume continues to go down on its own then it is a problem with the tv set itself. If the problem stops with the remote out of the picture then it is a remote problem. As far as powering the unit off may be a similar issue. If there is an on/off button on the tv and it works to turn the power on but not off then it is a tv issue. If the remote turns the tv on but not off it may be something as simple as the wrong code being programmed into the remote(universal remote) or if it is the factory remote it may be an issue with that. You could try getting a new universal remote that works with your unit.

TV Volume goes up by itself and remote wont work


Hi,

There are 2 reasons that this is happening in respect to the problem commencing after your daughter has cleaned the tv. Either your daughter has sprayed the volume button with cleaner and fluid has got into the the graphite pad under the button and conducting as though the button is being pressed continuously..or she has put too much pressure on the button if it is a metallic plate contact switch.One way to find out is by pressing the down volume button.does it it click ? if it does.try the up volume..If that doesnt click the problem is the metallic plate is dented in making contact hence a new switch. Another cause ive seen is cleaning the remote control with cleaner and fluid has got into the remote and it sends signals to the tv all the time..If the remote control is hidden under a cushion and the problem stops, then the remote control is at fault and needs drying out..Hope this helps :)
