Try another set to see if does the same - if so, then it is your box. If not it is the tv. If still under warranty have it fixed before the no sound becomes permanent.

SOURCE: proscan tv surround sound hook up

This depends on whether you have digital cable box or not. If you have a Digi Cable Box look for the red/white RCA output and connect this via RCA cable to the Red/White Audio input on your surround.

If just Basic Cable look for a red/white audio output on the back of your televison. connect this to the Red/white in on your surround. Could be called tv in or auxillary.

SOURCE: Sound quality poor

Try moving the audio and video cables to a different input.
Or the cables maybe bad. That's what happen to me.

Follow these steps to correct humming issue:

3. Turn volume to zero
4. With remote enter 9 8 7 6
5. A menu will appear on left side
6. Arrow down to backlight and with right arrow key move number from 81 to 83, press menu button twice,
7. Turn up volume and listen if hum is gone.

I can't confirm if this works at this moment since I don't have access to my TV.

SOURCE: remote control will not operate.

Make sure the remote works by pointing the remote to a digital camera or cellphone camera and look on the screen

if it works, it should be a light from the remote
and if is broken you can get it from here

I have a 42 inch Hitachi plasma tv that is making a very loud static noice coming from the internal speakers. It stays at a contstant very loud volume unless I completly mute the tv or turn the volum


Based on what you have tried if a buzz or loud static via the speakers you have something wrong in the audio output circuit of the set--problem here is that circuit may be part of the Main board that processes all signal---a look inside---following the speaker leads back would lead you to that board.

A simple thing to do to narrow it a little (you may have done this) is with sound all the way off put your ear to the internal speaker--hear anything at all like a deep hum?

Depending on age of set and cost of the board likely bad it may or may not be a do it yourself repair.

Just bought E420VL 42" LCD


Go into menu, sound set-up, and switch SRS to off. It's a vizio thing they came up with to act like "Smart Sound" where commercials won't be louder. It is total BS and does not work, it makes your normal sound fluctuate. Worked on all 3 of my Vizios. Hope it helps you.

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.

PS32500 32" TV Problem


The sound that you hear is coming from the sound detector not working or not receiving any audio. If the set is set to a second audio (SAP) program this could be you trouble. Some programs are broadcast this way. (such as Spanish for Spanish speaking people. Check you audio program settings.
