No hope. I have replied to this sort of question elsewhere but Behringer are very protective of their stuff and won't even let us have diagrams. Only Behringer service. If anyone has any Behringer service manuals / schematics we would love them
The fault is not with the speakers... It is with the noisy audio system common in computers. Get a decent USB audio interface and use balanced interconnect cables to solve the problem.
This sounds like an internal failure, probably something overheating since it takes time to recover. Behringer OFTEN puts thermistors to sense temp on heatsinks that shut down in the event of overtemp.
If you are not electronically adept, best to take this in for repair. If you are able to work on electronics, try using circuit cooler to isolate the failure. First a good visual inspection followed by the finger test searching for hot components... Do use care where high voltages are involved, mainly in power supplies and input power leads, etc..
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.
