Hello, i received a broken BXI-6000D for repair. Problem here, one Bank of output Fet´s are blown because of some broken legs on that Fet´s. On the Backside some lanes are burned. I removed the Fets and repaired the lanes. Without the Fet´s, the amp is shortly power amp, and then off again. Also the relay´s sounds very weak when they clicking. If pictures needed i can make some. Can anybody give me an advice or supply an Diagram?


Regards
Achim
 
Replaced all damaged parts. Amp is powering up, LED is green, Rail Voltage is ok, but the relay´s not clicking. Got no power on that relay´s. If i measure from Battery Minus to the relay i measure +12V, but if i measure direct on both connections on the relay there is nothing. Also no clicking. Checked the Voltage´s on the audio drive board, all voltages ok.

Soldered the Bridge, Amp powers up. Relay clicking, but directly the relay disengaged .After the second try powering up with remote, there was no more clicking at all. Green LED still on, current 1,5Amps. Before i put the solder bridge, when the amp powers up, i heard a hissing sound from the output inductors ( sounds like charging the capacitors, because the frequency of the noise rise until its gone)
