Question about Electronics - Others

4 Answers

I believe my grandchildren have been fooling with the home entertainment system. Upon returning from a trip, we could no longer put the receiver on mute; it simply lowers the sound to a low, but very audible level. Both the remote and receiver volume controls fail to bring the volume down to a "no-sound" level. There is always a very clear, but low level of sound present.

    Thanks for the quick reply. 1. I have checked the remote and all buttons function properly. 2. The mute function is not diabled on the receiver. 3. The remote mute works to this extent. There is no way that I can turn the volume completely off with either the remote or receiver volume controls; the volumn simply quits going down at a certain point and goes no further. So, if the volume is down as low as I can get it to go (it's still very audible), the mute makes no difference. If I ramp the volume up to a slightly higher level normal, the mute will take volume down, but only to the lowest level possible with the controls; it's still at a level that would be normal to most lsteners.

    I have tried, over the past 24 hours, to go to the menu and restore factory settings. Unless you can lead me to it, I find no such option in the menu. I have downloaded the manual and it gives no such option. So far no luck. Using either the remote or the receiver, it is impossible to lower the volume level below a normal level. Mute is only effective when volume has been raised to a very high level, then the mute will bring the volume down to the same listenable level as before.

    I have a home entertainment system, so everything is plugged into one surge protector. I need more specific information in terms of what power cord I am uplugging. So far, the emphasis has been on the receiver. Is it the receiver I am unplugging or the TV?

    If solution 1 and 2 fail, is it the receiver or TV that I take in to the tech guy?

    Thanks, your approach sounds like you understand my problem.

    Votit; We live 100 miles from where th Best Buy location is and we are planning on making that trip tomorrow. If I need to take a component in, I need to know which one. In your last message you provided three approaches, but didn't identify which component I should be unplugging in solution or which component should be taken in to the tech people. Please identify those components for me.

    Thanks, Neal

I'm just guessing here:
Chances are there are two or more units delivering sound. It's possible they're delivering sound from the same source, but at different levels. Say TV speakers and extra speakers. One set of speakers are turned off when you press mute, the other is not. If you, after you press mute, try to locate where the sound is coming from, compared to after you unmute, you will see if my hunch is correct.

Do you have two remotes, or just one? See if there's a volume control on a sound system receiver, and if turning that down makes a difference.

I have read what you have tried so far and there seems to be one thing that could do that..Have you noticed any change in the wires?Is there any speaker connected to the tv or dvd player directly which cause no effect when you lower volume in the home ent. system? Another thing which sometimes happen in connections is when the jack is hanging out or not fitted properly there may be a close connection which is allow electricity to the let's say in built tv speakers?Let me know if that helps.Also check all wiring properly from and to home enter. system.

ONE: First thing to do is a hard reset. Merely unplug the power cord for 4 hours, then power up again.The purposed of unplugging is to dissepitate the stored current in the memory IC,so the program setting will gone.

TWO: If the reset does not help, try disconnecting anything on input 2. For example, if you have a dvd player and a TV connected to that input, the reciever the home entertainment system may be sensing its presence and switch over to it. (Especially, if the device is left ON.)

THREE: It is possible the controller IC is defective,it is controlling the volume up and down and is wandering around (electronically speaking). In this case, the set would need to be seen by a tech who can get inside and test the circuitry that controls the function switching. Lugging a big set like this into a shop is not easy, but is will save you lots of money compared to having them come to your home.
Let me know if you need more....

Hope this may help;

  • First check all the buttons on the remote is working may be its just the mute button which is not working.
  • Second go on the setting of your home entertainment maybe the mute is disable just restore the factory settings.
  • Third if you have a universal remote use it if it works the problem is the remote. Hope this ideas will help you to resolve your issue.
