on most mixers, there is a master control slider..if its on zero you wont get anything..raise it slowly to a desired level..it should have something then if not take it to a music store and let them educate you on how and where most things are and what they do..they can help you with its operation..
What kind of CD unit are you using? Is it a portable, rack-mount, stand-alone, or via computer output? This information is necessary. I will be glad to help otherwise.
ALL LED's should NOT be lit all the time. If thsy are, there is a failure in the power supply.
plug headphones into the 1/4 inch main output jacks on the top... you will only hear sound in the left side headphone for each. This would verify the preamp is working.
Guessing this happens each time you switch on so it's not a power problem.
Amps have built in mechanisms to shut themselves off to protect from overheating. First thing to do is check the vents are clean and the fan is working properly.
I will give you a hint about selecting a repair facility. You will need to find a repair service that is CAPABLE of troubleshooting to the component level. Replacement modules in this are essentially NOT available from Behringer so one has to replace individual components.
Assuming your PAN controls are all at 12 o'clock, it looks like you have popped one side of the power amp. Please read my tip on here about the HAZARD on the "A" channel of PMP powered mixers. Essentailly, if you use Speakon to 1/4 inch cables or adapters the BARREL or the SLEEVE of channel "A" connector is the HOT side of the speaker and touch ground with it and goodbye Channel A side amp. They don't tell you about this in the manual. The tip of the plug is e cold side of the amp output UNLIKE channel B where the tip is the hot side. They do this to make it easy to implement "bridged mode".
Reepair of thes amps takes skill. This likely has the DPA300 module in it and you will find one side fried switching transistors and often a Zener diode. Sometimes the circuit board will have arced and be damaged.
You will have to have it repaired. Also read my tip regarduing the PMP mixer/amps that if you use 1/4 inch cable plugs to speakers, the SLEEVE of channel A is hot, not the tip. It the sleeve shportss to somehing that is ground, goodbye Channel A or more. This is not in the book.
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.
