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

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.

Europower Beringer PMH3000 power turns on then turn off?


when you turn on the AMP and the red light comes on give the amp 2 seconds and turn it back on the red light should turn off. That is what I do with the amps at my church and it works for me, I hope that this works for you too.

Amp keeps blowing speakers


If the amp blew the speakers , it sounds like the amp pumped HIGH levels of DC voltage into the speakers.

Get another amp and not Behringer,not Pyle,not Gemsound and not Numark.

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.
