You have blown the power amps in the unit. This is why you must insure that the speaker leads cannot be unplugged while unit is powered.

I don't know what model mixer you have, but ones like PMP3000, PMP5000, PMP1280S use a switching class D amp that arcs through a circuit board.

One can get a replacement:

I have NOT done business with this company before but you need to see if the HCA2400 module is what you have in your unit. Note that it has covers on the unit pictured at the site when installed.

I have repaired these, but it is an extensive process including carving out burned board material and replacing many components.

Behringer b212 power keeps shutting off

What a surprise! This is not unusual. If you drive these hard they do tend to shut down. If you are not driving it hard and are not running into clipping there is obviously a fault and it will have to go back to Behringer.

Hello, I just bought a BEHRINGER MS40 from an authorized dealer "SENIA" from Romania, I'm from Romania by the way, the woofer speaker from the right side is making noises when the frequency is...

Have you connected the Left speaker to the right speaker using the supplied cable? If not, connect the cable to the socket on the back of the right speaker labelled "to left speaker" and on the left speaker, to the socket labelled "from right speaker"
If this still doesn't solve the problem, try swapping the input cables (put the white plug in the red socket and vice versa) to see if this makes the left speaker produce sound, if it does, check the connection at the source to check the plug(s) are in all the way. If there is still no sound in the left speaker, unplug everything and do the following:
connect the left and right speakers with the supplied phono lead (Probably black) between sockets labelled "to left speaker" and "from right speaker"
then connect the source to any of the inputs on the back of the right speaker (ensure if using the red and white phono inputs that both are connected)
finally plug in power source.
Hope this helps

Behringer static

Cease using this till repaired to avoid further damage IF the sounds exist with cables unplugged... Some noise is normal if gain control is way up. Make sure the master gain is at halfway so you aren't getting all the gain at the input...

I have behringer speakers and my speakers just wont turn on. i checked the fuses. thats not the problem. what now?

The plural part of speaker makes me wonder, but let's not go there.

It's unlikely that the Behringer fairy is going to show up at your door, so try this support link and pick your circumstance.

Amplified speakers are annoying for this reason. If you overload the input from your computer sound card, you probably get the chance to blow both speakers at the same time. Amplified speakers without an amplifier aren't worth very much :-)

Clip light

It sounds like one side of the power amp has shorted. May be hazardous to the speaker so best take it to a shop for repair. If speaker stills sounds OK, probably the clip detector transistors have failed.

Have Beringer Europower PMH 1000

The clicking could be the protection relays kicking in and out.

Check your speaker cables for short circuits.

Also make sure that the load you are applying to it does not go below the minimum impedance which i believe is 4ohms on this unit.

I unpluged my speakers from my tower and now they won't work after pluging them back in

Make sure the speakers have electric power connected and the power light is on for at least one speaker. Make sure the volume on the speaker control is at least half way up.

Make sure your volume in Windows is at least halfway up and not muted.

Unplug the speaker jack and re-plug it firmly into the hole you just removed it from. Test for sound.

If no sound, unplug and try another hole of the same size on the back of the computer and test for sound. Continue testing until you have tried every hole the jack will fit into. One of them will very likely work.
