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.

sometimes the cause can be heat build up caused by dust inside the unit if you disconnect from power then remove hte cover screws get a soft paint brush and dust of the fans and power boards dont use a vac with a metal handle or hose as this can cause a static charge on the board and damage components>hope this helps A

Oh yes... I have repaired several of these supplies.
For the IGBT's use APT28GA60BD15 which are pricey at $9.28 from (still lower than alternative sources. Getting the heatsinks off, one of which has a thermal sensor as well is a real pain! Transformers don't fail...
The C2655's are really 2SC2655-Y and those I get from Allied. The mating 2SA1020-Y I believe is available either at or
You will LIKELY find the IR2153 chip is blown and that I had to get from Allied. Usually one of the PL4148 surface mount gate drive speed up diodes is blown either short or open (D24 and D25).
Often transistor T9 is gonzo (BC856MTTCT).
Often the 10 or 22 ohm wirewound charging resistors are blown open. I use TWW10J20RE as replacemens for those. Be sure and use silicone to help support them.
Now when you are done with that, you need to find WHY the supply failed. It is either because a ceramic cap across the 85 volts failed OR one of the power amps arced out. If the unit has the HCA2400 amp in it I will tell you what happens: In the vicinity of the SPF9640 MOSFET and a big surface mounted cap will be an arc between layers of the multi-layer circuit board. This shorts and fries the IRFP250 MOSFET and BOTH SFP9640 MOSFETS. The repair of this is major involving carving out the "cancer" and reinsulating with epoxy and replacing blown carved out traces with hookup wire. The proceedure I can't document here, but failure to correct this will result in power supply failing again.
FOR YOUR SAFETY ONLY work on the supply using an isolation transformer. Use a 150 Watt lamp in series for testing to act as a fuse so you don't pop the supply again. DISCHARGE the 85 volt outputs BEFORE plugging the amps back on the power supply.

SOURCE: my behringer europower EP2500 poweramp has a bad

There is a possible noise build up on your CH2 due to failure or weakness of the LCR network of the preamp circuit. It could also be a noise within any semiconducctor or the preamp IC. Unless you can do a signal test with the elimination of the input to the output amplifier, the fault will not be say to isolate. Hence if youarre familiar do the test by approching from the output amplifier's input, proceeding to the main input where the faulty section can be identified. Hope this helps. Good day

No sound coming out on both r and l channel

Oops! Smoke from on of those is not unusual, as behringer is notorious for bad solder joints and BAD Power supplies. Anyhow the amplifiers are "most likely" OK. but your powersupply is shot. My PMH 3000 did the exact same thing. And here is the bad news. Behringer is also notorious for the lack of assistance in case of problems and will advice you to have the unit repaired at an approved service point. If however you are ok with electronics you can have a go yourself, manuals are few and (very) far between. I have some diagrams and stuff, so if you need some sing out. I have 2, MX 3282A mixers, nothing but trouble! Sorry I can't help you any further, Good luck.

Hello! I have a Behringer EUROPOWER PMH 1000. But the power board burnt source. What do I will acquire another, or fixable?

Often teh power supply fails because of other problems. Unless the board has flame damage the parts that are defective can be replaced... Getting some of the parts that are special can take time. Most of the components are available at many sources however. The SPS400 power supply can be repaired.

Here is link to schematic that should have the SPS400 as well as the rest of the PMH1000 on it.
