    • 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.

    • 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?

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

my fuse holder the plastic broke because there is not enough pressure to hold in the fuse and turns on and off

Test esr of all small electrolytic caps eg. 100uf in primary side of ps. In area or 16 and 8 pin dips. Have had this problem cured with caps replaced , often several, small ones in this supply. Especially units that have ran a long time and have heat stressed those elcos. Presently having a problem that is not caps but i suspect theViper22a ic as there is no standby voltage at all and this chip can be “sneaky", sometimes working and sometimes just not firing up.hope you have access to an esr tester as these little caps don't always bloat to show their failure.

Thanks for your detailed explanation. How can I simply replace the fuses? I have new ones but the fuses don’t seem to just screw out to be replaced. Thanks in advance for your prompt response.

I have two of these that are not passing AC power from the first power supply. I assume its AC? I have the schematic for others if you still need. it doesnt list part numbers/types. Anyone know what this should measure on the blue and brown wires? Listed as X7 and X8
