Мои познания в ремонте данного вида техники: Занимаюсь ремонтом Наличие схемы: no Hi guys, I have a problem repairing this Behringer NX6000, channel A is in protection. I found 2 irfb4227 mosfets on a shorted branch and I also changed the pwm IC17 20957, this branch works in bridge with another branch that has nothing in short but when I turn on the amplifier in output I have about 5V and immediately goes into protection. I also checked if the stop comes from the SD pin and I confirm that the problem is not there. I also checked the dual voltage which is present +84v and -84v, the voltage on pin 11 of the PWM I have 12V in reference to the -rail so everything is ok. What can I check? the mosfets are ok, I don't have the exact NX6000 diagram but I refer to the NU6000 diagram, can you help me?
