EUROLIVE B215 no power, replace the fuse same thing, fuse are good it came on a few times then power goes out again with no fuse damage, now power stays off

Your right, replacing the fuse won't fix anything, it will blow again, I've used the repair kits a few times on the power board that shopjimmy sells and had good luck with it. Samsung BN44-00201A Power Supply Component Repair Kit (shopjimmy.com)

Sounds like you have a short in the amplifier, likly in the power supply section.

Power amplifier circuit fault. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" or "Magazine" will make surf easy. Pull up older posts. Surf the site with patience. Do a search by type in the brand name of your device at its search box.

Hello,

Eurolive Active speakers from Behringer suffers of bad power supply/Amp design, if you open up the back of your speaker you will probably find that the AC connector has a burnt or loose connection as well as a black spot, if not, check the power supply/power amp coils for cracked connections, let me know for improve help.

I had same issues with mine. Check T1, T4 T11 and T7 on Crossover/amp pcb pcb part number is P0981 It is blue in color. These are the output Mosfets. If they short the protection circuit causes unit to cycle into protection over and over. ALSO if they are shorted I would suggest replacing the Gater drive IC IC3 for T1 and T4 IC 11 for T7 and T11 as this is the main IC that drives these MOSFTETS . Here are the part numbers T1, T4, T11 and T7 are type IRFB4227. The IC in mine was type IRS20955 ( Note: this is no longer made by IRC as they had issues with them shutting down and not working correctly, the replacement is IRS20977) good luck.

Check the internal wiring. There may be a loose connnection and this is VERY hazardous to you amp !!!

These may also have a self reseting fuse and that MAY be damaged.

You should discover the problem when you open up the unit.

Check the DC resistance of the speakers. I should not be over 10 ohms. If it is something, probably the speakers are blown.

That 600 Watts is peak and you should use an amp of say 300 Watts a side max to drive this for safety.

You may find a fuse inside, but not likely you would be so lucky... Also if the amplifier failed it could have sent DC current through the units and fried the voice coils of the woofers. The horns often have capacitive coupling and usually will survive.

You can fiond 15 inch replacement speakers on Ebay... HOWEVER get the dimensions as they often vary and may not fit.

the same problem in the B300 is fix by changing ic 7815 and ic 7915. Dan

The Amplifier will have wierd, notched, circular speakon cable connectors on the back, two, one for main left and one for main right. Press the button in on your speakon cable connector and twist it and lock it into place on the amplifer for right and left attachments, then do the same to your speakers.

Hopefully this helps.

I would suggest taking a look at the power module if that can be replaced. The Fuse blowing may have only been the beginning of the problem. Any recent issues with under or over voltage in your home?
