Hello,Eurolive Active speakers from Behringer suffers of bad power supply/Amp design, if you open up the back of your speaker you will probably find that the AC connector has a burnt or loose connection as well as a black spot, if not, check the power supply/power amp coils for cracked connections, let me know for improve help.
Diodes probably fried. You made contact with the tip to ground. $3 or $4 part, but you probably fried more than one. $100 to $175 in labor for them to fully diagnose the problem.
I bought a 3rd B212D unit that powers on, has white noise, no music. I took the 8 screws off and discovered that the solder connection at the woofer had broken off. I surmise that either the unit was dropped or the speaker wire had gotten hot over the years. Since the amp had an open output from the break, the high output burned up as I heard a pop when I turned the volume up. . If your volume wasn't maxed out, you could check the wiring and make sure it is connected & save yourself some change!!!
You are PROBABLY driving it too hard and the thermal cutout is activating. This is only a 12 inch speaker and should comfortably fill a 20 foot square room. If *********** could not stay in such a room, you are playing it too loud. Try reducing the volume by 3 DB and see how long it stays on. The specification on MOST of these powered speakers and speakers and amps in general are victims of "specsmanship"... that is false advertising to make sales. This size speaker is NOT applicable to outside venues for the most part. You could also try putting a fan blowing on the heatsink to keep it cooler as that might help.
D3 is shown as a 1N4148 small signal diode... I hate to say it, but if that diode blew you have MAJOR damage to other part(s). The minimum, with D3 fried, is that C10 is shorted causing the problem. If that C10 is not shorted, then high voltage must have been applied to the ring from that input jack frying R5 (1K), R6 (12k), C7 (1 nf )and IC1 which is a 4580 op amp. By the way C10 is a 47 pf cap that is likely surface mounted and most likelly shorted..
The parts cost I suspect would be about 1/2 of the new cost of the units... certainly by the time you add shipping cost... Find a competent repair shop.
To get the parts you would need to first call Behringer 1-425-672-0816 to get a part number and an incident number, then deal with FullCompass which distributes the Behringer parts.
Cost by replacing the amps would NOT be cost effective.
In looking at the schematic, assuming there was a voltage surge on input power, possibly the diodes and capacitors in the power supply are damaged if the fuse blew and was replaced.
If the speakers were powered by a different receptacle than the source feeding the audio to these was, ground bounce may have destroyed the first input stage.
You need to give us current symptoms so we can direct replacement of bad components.
You will need an oscilloscope and a good grounding in electronic servicing to attempt a repair.
But, check the signal routing. Refer to the user manual.
It sounds like you're experiencing a couple of issues with your Behringer Xenyx 1204FX mixer. Let's address each of these problems separately:
DSP Display Not Illuminating: The fact that the DSP display works when you press down and turn the knob suggests that the issue might be related to the display itself or its connection. Here are a few steps you can take to troubleshoot the problem:
Check Power Source: Ensure that the mixer is receiving proper power and is turned on. Sometimes display issues can be caused by power-related problems.
Connection: Make sure the ribbon cable or connector that connects the display to the circuit board is properly seated. A loose connection could be causing the display to not illuminate.
Faulty Display: If none of the above steps work, there might be a problem with the display itself. You may need to contact Behringer support or a professional technician to get the display repaired or replaced.
AUX 1 Send Not Working: If the AUX 1 send is not working as expected, there could be several reasons for this:
Routing Settings: Make sure that the AUX 1 send is properly routed to the desired destination. Check the routing options on the mixer to ensure that the signal is being sent to the correct output or destination.
Level Controls: Verify that the level controls for AUX 1 are set correctly. Make sure that the AUX 1 knob for the specific channel you're working with is turned up.
Effects/Processing: If you're trying to send a signal with effects applied, check if the effects are set up correctly. Sometimes, an incorrect effect or routing setting can affect the AUX send.
Cable and Connections: Ensure that the cables connecting the AUX 1 send to external devices (such as monitors or effects units) are functioning properly and securely connected.
AUX Master Level: Confirm that the AUX 1 master level (usually located on the main output section of the mixer) is turned up to an appropriate level.
If you've gone through these troubleshooting steps and the issues still persist, it might be a good idea to consult the user manual for your Behringer Xenyx 1204FX mixer for further guidance. If the problems continue, you may need to reach out to Behringer support or consider seeking assistance from a professional audio technician or repair service.
Hello Geoff, try using an external processor and check that it works well, if so, the problem is that you have the Jack connectors of Effect sending and those of Return of Effects, dirty
Apply a couple of drops of oil, type WD40, to a Plug connector and insert and remove them repeatedly in each connector Jack for sending and returning effects
I hope you can solve the problem, comment the results
Greetings Franco Dosil
Hola Geoff, prueba usando un procesador externo y comprueba que funcione bien, si es asi, el problema es que tienes los conectores Jack de envio de Efecto y los de Retorno de Efectos, sucios
Aplicale en un conector Plug un par de gotas de aceite, tipo WD40 y entralos y sacalos repetidamente en cada conector Jack de envio y retorno de efectos
Espero puedas solucionar el problema, comenta los resultados
Saludos Franco Dosil

Check all the wiring connections on the speaker. Check the plug in points for the cables are not loose in the body of the speaker or the connector plugs themselves are not loose in the actual plug sockets.
Next you will need to get inside the speaker body to check the connections and soldered joints. Take a good look at the back of the cable plug sockets and to the back of the actual speaker cone connections. Check each wire at Both ends for damage. No sound at all suggests the issue might be at the 'Input' where the cable plugs into the back of the speaker body.
