Is there any fuses inside the unit or just the one on the back inside that cylindrical fuse holder that you can push, twist and remove? Mine will not power and I want to open up the box if there is any fuses there and I will check for cracks near the pots, etc. as well while I am inside the power box. I already removed the box fromt heback. Just need to open it up now.
Mine will not power up. Is there any fuses inside the unit or just the one on the back inside that cylindrical fuse holder that you can push, twist and remove? I want to open up the box if there is any fuses there and I will check for cracks near the pots, etc. as well while I am inside the power box. I already removed the box from the back. Just need to open it up now ancd check things out. Was hoping to find a replaceable fuse inside to make the fix easy.
There is 2 fuses in there which were fine. I soldered where the power plug comes in and attached to the power circuit board, the one that the power transformer is plugged into with 2 separate wires that have the speaker terminal type connectors, a blue wire and a black wire. I got power. Now, the clip light stays on and no sound. I made one of these audio probes to trace where signal stops -http://billmaudio.com/wp/?page_id=1254 .
I got signal on the input jack of the 1/4 inch when plugged into it, playing a 400hz sine wave. I also got signal on the XLR output that is used to chain signal to another speaker. When I checked the amp board, I got no signal anywhere on the signal path. I took apart my other speaker, same model and after exchanging different parts connected to each other, I isolated the problem to the pcb board that has the volume and EQ modules on it and the 1/4 input, the XLR input and the XLR output on it for connecting to other speakers.
I looked at the board thoroughly and see no signs of parts being blown at all. I am wondering what to test on it. I have a multimeter that does volts DC and AC and also measures Ohms.
Does anybody know what maybe usually goes out on that little separate pcb board I am referring to?
Thank You,
Lance

Hi,
Best and safest is to have a good electronicus check it out.
i've worked on these kind off things, and i assure you not everything can be simply solved without experience, especially when talking about a decent type like Behringer ;)...
Hope this is helpful, and greetings,
Olivier.

You DON'T replace the board. If it is cracked, you bridge insulated wires around the cracks and epoxy them down.
Often the pads break from the traces near the pots. Look for a small crack between the pad of the pot and the circuit trace leaving it. Common problem.

These have a crossover inside as well as a fuse. If it is blown the link is gone and only the horns will work.

I have seen some of the 1/4 inch jacks that had the mounting nut overtightened and it resulted in the riveting of the threaded part to the metal where the wires connect being stretched to the point the riveting came loose, breaking the contact.
The only way to know is to open the unit. Some of the board mounted "plastic" wonder jacks one can't even see without unsoldering them from the circuit boards.
When replacing do NOT overtighten the mounting nut !!!

In my B215 there demage HighFreq amplifier (TDA7293) after "CLIP" light on :(. I cant find failure... Anyone knows what wolud happened?

There are 2 fuses inside fyi. I opened mine up to check.
