The volume no longer goes up or down, it just stays on mute

That normally happens when the memory battery on the motherboard fails. It no longer remembers what your last setting was.

No service manual for it.

I tried those things but didn't help. On my sceptre tv, the volume continues going up or down on its own shortly after changing via the remote. I found that if I press the Mute button 2x (off then on again) after setting the volume it will stay put! The mute button stops it from changing on it's own. Its only a work-around that works for me but maybe it will help others.

Replace the remote?

I had this same problem and it was due to their instructions which do not adequately explain the setup procedure.

On my own, I was successful in programming volume up but that was all. I assumed that for volume down I would hold the power button and the VOLUME DOWN button and wait for the flashing light just as I had for volume up. Problem is, you never get a flashing light.

Today, I spoke with a rep from Boston Acoustics who patiently explained that step one of the instructions has to be done the same way each time as it is the step that puts the soundbar into programming mode.

It is only at step 2 that things change.

The solution is to hold the power button and the Volume Up button every time in order to get the system into programming mode. Once the light is flashing, in order to program Volume Down, you then hold the Volume Down button until the light goes solid. Once the light goes solid, then press the volume down button on your remote 4 times slowly. Works like a charm.

Works the same way to program the mute button. Follow step one to get the unit in programming mode. Once the light is flashing, hold down only the mute button until the light goes solid. When the light goes solid, press the mute button slowly 4 times.


OBTW, this was programmed with a Logitech Harmony 650 remote unit.

Most of the time it is the touch button assembly on the tv. The Volume down touch button switch is sticking.

To enable/disable the silent feature on an iPhone, simply look to the left-side of the phone. There will be 2 buttons there:
1. A small, switch that goes left/right. 2. A longer longer that can be pressed up/down.
Button #1 is the silent toggle switch. Moving it to the left enables silent-mode; to the right disables silent-mode.
Button #2 is the volume adjustment button which will raise the volume if pressed up and decrease the volume if pressed down.
Note: If you press the volume bottom down all the way, the handset will mute itself. When using the volume button, a volume indicator will appear on-screen to indicate how loud/quiet the phone is. If there are no white bars present on the indicator scale, then the iPhone is muted. Press up on the volume button a few times to increase the volume and disable mute.

Are you sure it's not the TV telling you that it's muted? I went down the tubes on that one myself.

The receiver's Mute can be defeated by just rotating the volume knob upward. Ditto with TV's.

I have the same problem. After trying the adjust the volume on the screen, it went all the way down and slided back to mute everytime after I pulled it up. The volume button on the right didn't work either. I called Archos tech support on Feb 13, 2011 and they said they no longer fix this product because it's 4, 5 years old. But they would offer me a 15% discount for an upgrade. Why would I want to buy the same brand again if it's so unreliable?

confirm that volume contro plus (+) button does not stuck inside.
try to apply good contact cleaner in volme button and press it many times until it released.
