Re: Behringer PMH 518 M
Quit replacing the fuse... you are doing further damage in the unit.
Likely the MOSFET power transistors are shorted and probably there are several transistors and other components ahead of those that are fried.. These are NOT well protected and the failure of a single part leads to multiple failures, often accompanied by circuit board damage when fuses are replaced with problem still existing..
Unless you are skilled at electronics you need to take it to a competent shop for repair.

Hi Robert, The problem with ceramic fuses is that you can't tell if it's blown unless you put a meter on both ends to check for continuity. You probably have a friend that has a multi-meter sitting in a drawer somewhere, or a trip to the local Radio Shack will tell you right away - as well as likely finding the correct value fuse. Replacing it with a ceramic is not as critical as matching the AMPERAGE of the fuse (the Behringer site might be helpful: http://www.behringer.com/EN/Support/Find-Answers-or-Ask-Behringer.aspx And no, the fuse didn't die on it's own, but are most prone to failure at turn on - so this time when you plugged it in after 3 years - it was time to go.
For goodness sakes do NOT replace the fuse... doing so causes more damage inside. Likely one of the power amps has shorted and may have damaged the power supply as well. Also please read my tip on Fixya regarding a HAZARD with channel A if you use 1/4 inch plugs with the speaker cables. Essentially the sleeve of the channel A plug is the hot, and not the tip. Ground the sleeve of the plug and you can blow the channel A amp. YOU WILL NEED TO TAKE THE UNIT IN FOR REPAIR... THIS IS NOT A DIY REPAIR!!!!
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!
If it is brand new, it is likely "pilot error" as setting these up if you are unfamiliar with mixers can be frustrating.
There are several things that must be done to have a working system. Correct speaker cables are one and the setting of all the knobs are important...
DO NOT REPLACE FUSE. If any LED's are on, fuse is OK. If fuse blows, service the unit before replacing fuse to avoid further internal damage.
Make sure speaker cables are good.
Set the level control for the channel you are testing up AND you may need to press the "PAD" button to change the input gain. Turn up the master gain.
Depending on the source you are using, line or mic you may need to change the PAD button.
NOTE: This mixer does NOT have Phantom power and cannot be used with CONDENSER microphones requiring phantom power. You will get no audio from a condenser mic without phantom power. You must use dynamic mics with this mixer.
