Step 3

              Detach the Behringer Eurolive B212D Electronics Box

There are two silver, 6 mm-long machine screws with two 1/8" inner-diameter washers on the exterior of the metal electronics box; remove these first using a #2 philips screwdriver.
There are five of the same type of machine screw (silver, 6 mm-long) remaining around the metal electronics box’s exterior; remove these as well.
You should have removed a total of 7 machine screws and 2 washers.
The reason for removing the two screws with the two washers first (or replacing them last when reassembling) is that their holes are actually slots. They are designed as slots to accommodate slop in the assembly, and if unscrewed out of order, you may have difficulty while removing - or possibly even damage - the other five screws.

Step 5

Inside the metal electronics box housing is a white clip attached to a small PCB; remove this.
The white clip in this image has been glued, indicating that the manufacturer may not expect the end user to remove this clip; it is difficult to proceed with the disassembling without doing so, however, because the rest of the speaker does not provide a sufficient surface on which to work.
Snake the clip head through the hole in the metal electronics box casing.

This PCB does not convert electricity, and is rarely what fails. AC leaves this board and gets converted to DC at the rectifier bridge, which is part of the main amp PCB. This main amp board is where 99.9% of issues arise…

Do you know where I can find replacement boards for this speaker? It takes about 20 times of cycling the power button for it to finally come on. Can’t seem to find parts anywhere. May not be financially smart to replace the board, but if it’s not that expensive, I feel it’s worth it.

Hi. Why dont you fix the board?

Jonathon - Aug 19, 2017

Has anyone got a circuit diagram for the power board. Is it a switch mode power supply - the power plug indicates 240V or 110 V AC which would normally indicate it uses a switch mode power supply at the front end
