All amps have fuses [multiples]. Check where the black wire line connects to the unit itself. Look carefully as it may be sealed within that connection. A small, sharp object may be used to pry it open [unplug unit prior]. Fuses are usually located on the PCB and although they may not resemble the "glass type" they also look like little resistors. A DVM is your best bet in which to troubleshoot this problem, otherwise you are just doing a simple visual with no true direction.

Even the main transformer (primary windings) are thermally fused. Using a meter, check the primary for an open as well as the secondary. Should you have an open on the trans, it will be a costly fix. All depends on what happened when the amp stopped working. Overdrive? Underdrive? lalalalala

My europower pmp 2000 powered mixer wont turn on and the fuse appears good. I turned it on and it immediately turned off ,nothing smells burnt. any ideas on what it could be


This is likely a power supply failure, possibly brought on by a failure of one of the amp channels.

This is probably close to your supply:

Scroll down to "get manual" and click on that to download schematic. Ignore other download links.

My system will not come on. I've put a new fuse in it and I still can't get it to come on?


The power supply is blown and probably one of the amp channels. Repair will be tedious. They take out from 30 to 50 dollars of components typically.

Fuse blown on Europower PMP 3000. Where can I find a 10 Amp 250 V ceramic replacement fuse?


You don't need to use a ceramic fuse if one's not available. You can also use a glass cartridge fuse as well. Just be sure the rating is the same. Be aware, though, that fuses seldom blow on their own. Usually it's because something else has shorted. So don't be surprised if replacing the fuse only results in another blown fuse. Behringer stuff is notoriously cheap and under-protected, so by the time the fuse blows it's usually more trouble than it's worth trying to fix. But maybe you'll be lucky and it will be something simple. Good luck, and thanks for using Fixya!

Both fuses burnt and both clip and signal led on? seems to have full power behringer ep2500


Suspect an overload in either the power supply section or the devices on the main heat sink. In the power supply you are either looking at a transformer problem or semi-conductors associated with it. However since the clip and signal lights are on, I would go to the amp devices on the heat sink. If they are transistors test them with a Ohm Meter on the 1K setting in circuit even! You will soon notice which ones are gone! The meter will show like you had touch the test probes together!

The fuses have blown due to a short circuit, ie some part acting like it was a piece of wire. The chances are (with the LED's showing) it's the main amp semiconductors (on the heatsink) that have gone. The cause is either connecting a wrong (unsuitable) speaker(s) for the job, or letting the two wires (to each speaker) touch each other.

Nothing comes on on a europower ep2500 power amp


Hi...

Check fuse in the rear where AC comes in and there should be a couple of small fuses ( 20mm long ) inside the amp. CHeck those too

Trips on power up


It has a short circuit on the final steps of the outputs, maybe the common called "final transistors or power amplification IC (integrated Circuits)"are blown. You don't have the ability to resolve this problem, so take the unit to a facility authorized repair.

Behringer pmp2000 europower no sound


Probably the power amp has arced and popped a lot of components.

When teh amps go usually the final pwer transistors, their drivers and sometimes even the power supply gets zapped.

Check the output of the preamp at the inserts for the final amp with headphones to see if anything is coming through.
