I have the MS-40, and I experience problems with the power / power button - after a short time left speaker goes off line,

I haven't had any issues with mine. Over the years I've owned many pieces of sound equipment from Behringer and if I've had an issue they have always stood behind their products.

Yup, had the same exact problem. I thought it was the speaker to speaker cables, the Coax or Toslink cable and then my computers sound card but it wasn't. It drove me nuts. If it's still under warranty, send it back and have them fix it.

Mine turns off after approx 20 mins of no input, no matter whether running on battery or plugged in, and no matter whether on Bluetooth or wired input. It must then be turned back on with the power switch. There is no way to defeat this, and I verified with JBL/Harmon Customer Support that this "Standby mode" is normal behavior. This is NOT mentioned in the skimpy user manual provided, and is completely UNsatisfactory for my desired use. It's getting returned, unfortunately.

From what I have read, try turning off your bluetooth and the speaker to reset.

Sorry for the delay in responding to your question. I did not know the answer (I like the little blue lights, so I never tried to turn them off) until just now when I happened across the tiny info pamphlet that came with the speakers. According to that, the power button is the one on the backside of the big speaker (subwoofer). There is another button on the front side, near the bottom. It's easy to miss -- I never noticed it before. It turns the "BassPULSE" (AKA little blue lights) on & off

The same thing happened to me. So I sent it back for a replacement. The same thing happened to that one! So I sent it back for a refund & just gave up on the speakers. I'll save up my money for a brand with higher quality standards!

I had an issue where the power button needed to be pressed repeatedly in order to start it. This kind of an issue is being reported all over message boards. I did an exchange on mine to see if that would help.

I've had mine for several years and never had a problem with power buttons. (sometimes hit off when I mean on)

Speakers don't normally break. Maybe Altec has a driver for your speaker under technical support.Regards

If it's what happened to me... Everything cuts out... then the message on the unit says "Protection Mode" (or something to that effect) If so, it was after I pushed the unit too far back in the cabinet and accidentally broke the solder point on one of the speaker terminals. These connections are apparently quite fragile and it doesn't take much force to break it... causing the amp to sense a "short" in the system. This then puts it into the Protection mode. I tried opening it up to re-solder, but the PC board was slightly cracked- no dice. Threw it out and got another one... otherwise, they work great.

Yup, I think try pressing volume down and power all together, if not upper volume and power

I have the same thing here. It's normal for most powered speakers with an external power brick to have some audible sound when the transformer cuts to standby.

hi--yeah, I am seeing this as well, but I was able to press the "speaker" button and the sound comes back. it's really kind of frustrating, I am trying to figure out what to do about it as well.

Search for the woofer for the PMO.4n and see if it makes sense to replace just that speaker. Taking another route, depending on what is actually wrong with the speaker driver, it maybe fixable. For instance, if the outer foam is split but not the cone you can likely purchase a repair kit for under $20 to fix yourself. I have done this before (not on this speaker however) and had perfect success. Lastly, its Christmas time and you can suggest a replacement speaker system as a nice gift from someone to you.

I had a problem with my "volume" button. Contact Amazon customer service and they can probably refund you a part of your money, or help you get the problem sorted :)

Gary, just tried turning off (power button) the e250 as it was playing - when I turned it back on, it was exactly where I had turned it off. Any other test you might want me to try? Jerry

I have the same problem. Not only that, but there seems to be an issue with the power button whether using the remote or pushing the button manually. I like its features when it works, but this power issue makes me think I got one off of the line from late Friday production run because it is crap.

For mine I hold the power button firmly for about ten seconds. Takes longer than you'd think. I turn it off from the FM setting. Pressing the power button quickly cycles between FM and Bluetooth. It will play a sound and go off. Hope this works for you.
