Behringer Europower PMP 530M

[soulman25]

I have 3 Behringer Europower PMP 530M on my bench . They all have shorts in them . I did comparison checks between all the major componits , IGBTs & Mosfets BJTs and diodes on all boards. They check fine in circuit. Maybe I need to pull them out compleatly and check them that way. I don't have a schematic and Behringer wont help at all. I think its compleatly stupid that they don't help us techs at all. Any help on these would be thankfull.

The manuals are available only to their service agents. They are very basic. What shorts have you got? If a FET is short it reads short.

I found schematics of some similar item in my database - hope this helps

To Jon Snell. so far I've checked all componets for shorts . I found a couple of diodes that show a dead short that are associated the power supply. I will pull those next and check them . I also pulled out the final Mosfets or IGBTs and checked them they were fine. As some componets you have to pull out of circuit compleatlly to get an accurate reading.

To voltwide , I'm sure that I can use at least part of this schematic to troubleshoot my problem. Thanks.
