Question about Vizio VX37L Television

1 Answer

Speakers don't work

I've had my vizio tv for a few months and the speakers mysteriously went out. For some reason even when the volume is way up, you still can't hear it. They worked normally at first and now I can't hear a thing.

Let verify first to narrow down to where the problem can be. First, make sure the MUTE function is not activated, then check the on screen sound set up menu to make sure the speakers are not set to OFF. If the setting is OK, then attach the powered PC speakers to the Audio Line out RCA jacks (Red and White) to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find.

    Yes, it can be that the amplifiers si not getting the 12vdc feeding it or the IC just quit working, most LCD TV uses class D amplifier. To have it fixed will not be worth it. Just set the audio line out to VARIABLE so you can still use the TV remote to control the level.

I have a Vizio tv only a few months old. Bought brand new. When volume is all the way up to 100 it sounds like it is on 25 for a regular TV has been this way since bought


Check manual for audio settings. If nada you can always connect the video output of set to your audio system. Most of these sets sound lousy because they have very small speakers.

No audio to internal speakers,audio out to amp is good.


THIS AUDIO PROBLEM PERTAINS A FEW DIFFERENT NAME BRANDS AND TO MOST VIZIO Tv MODELS
MADE IN THE LAST 2-3 YEARS MAYBE EVEN 4+ I'M NOT SURE
WHEN IT STARTED.
I do believe your model is equipped with the SRS features which IS a formatted audio enhancement . Anyway go into the advanced audio settings in Tv's menu and TURN OFF the SRS tru volume leveling & the SRS tru surround feature. Additionally in the Tv's menu also has an option to turn off the internal speakers. And another common pitfall that I see happening to people. Is check the PCM and or LPCM option in both your Tv & your cable/satellite box's audio menu setup/settings. LPCM is Limited Digital Audio and PCM is Variable Digital Audio (VOLUME AMPLIFICATION) but
because it is a digital signal the two formats conflict, and the audio
will in and out.

My tv sound just went off for no reason have turned it off and on tried to adjust volume nothing mute is not on


No sound on ALL modes?
Let verify first to narrow down to where the problem can be, attach the powered PC speakers to the Audio Line out RCA jacks to see if you can get the sound there, if you do, then the problem can be in the power amp circuits, if you do not get the sound at RCA jacks, then the problem can be in the sound processor circuit. Please post back what you find. You may be better off if the sound does work through the PC speakers, to get the TV repaired; it will be more than $100 and up.

My vizio tv speakers are busted, how can i replace them


You can not use external speakers unless they are part of a home theater equipment (or similar device), I recomend you to try to adjust the volume settings in your TV first.

I want to hook up my bose speaker systerm to my new vizio tv


Real easy, get a RCA audio cable (red and white ends) that is long enough to go from the tv inputs to your receiver inputs. Plug one end into the audio out on the back of your tv, then plug other end into input on your receiver (tv, cd or vcr). Now everything going to tv will output to receiver also. You may have to go into the TV menu and under audio, set audio output to fixed. Then you can change the volume on your receiver which is best way to go.

**Advanced** If your TV and receiver has optical capability you can use an optical cable instead.

Good luck,

Verizon remote won't work


I am a Verizon tech and the remotes we use work for Vizio sets just fine. If for some reason the remote wont work and he tried 3 different ones then it has to be your set. I set FIOS up all day and have no trouble with those TVs
