Hello amp powers up but its in protect and has no output.
Shorted outputs or faulty protection?
Thinking about buying this amp just want a heads up on what I may be getting myself into??

The two 1D transistors on the driver board are the most likely suspects. Let me know if you need a photo.
About 50% of these that I get in are exactly what Perry says. You can replace em without pulling the driverboard (it's tricky, but do-able). Even when they aren't bad, I still put fresh ones in.
Thats how I did the BX2005D we worked on was stood the amp on end so I didnt have to remove the board again it was easy that way.
Perry, wondering if you could post that photo of which two 1d transistors they are. The last hifonics I worked on I replaced them all and I dont want to replace unecessary parts.
Is it a good practice to replace them all of just the two you mentioned?
I bought the amp, "should" be an easy fix!!
Theres 5 1d's on the audio board I was wondering which two are the common ones to go out?
The last amp I just replaced all of them including the 2d's and one of the op-amps.
I guess I will just replace them all.

The brutus 1208 you just helped me on had a failed op-amp. I replaced all the transistors on that board. I also replaced the one op-amp.
Why is it that just those 2 fail, and why does that cause protection?
Replaced just the 2 and the amp performs flawlessly and sounds amazing.
Thanks Perry and timwebb.
