    Behringer DJX 750 No power

    Hi has anyone got any experience with audio mixers ? In particular Behringer audio equipment ? I have a Behringer DJX 750 mixer which recently died I've opened it up to investigate and the only thing I managed to find was a blown 104M ceramic capacitor C15 which I have replaced with new and still no power to it at all. I read somewhere online in a forum from a google search and found that cap C24 which is a 1000uf 35v could also be the problem. Is there anything else I could have missed.

    Something caused the capacitor to blow up, check the diodes and the mosfet for shorts.

      Can we see good clear straight shots of the whole top and bottom side of the board. Those ceramic caps look to be snubber caps for those diodes. What is the Voltage rating printed on those ceramic caps?

        They are a 104M ceramic cap Budm so far I have replaced that and the 3 1000uf 35v caps and still no joy my next port of call is the transistor 7815 insulated Voltage Regulator KEC KIA7815API

          I'm just hoping it isn't the transformer because Behringer are being no help at all for any replacement parts

            Hey, I have the same issue. Although looks like No caps blown.
            suspect the transformer is broken. have you gotten a new one from behringer ?

              1. Check the fuse
              2. Measure DC resistance of transformer windings
              3. Measure AC voltage after transformer output.
