Alpine MRD-M no output. No 5V from pin 19 of ic Most of the chip is missing power from the lack of 5v from ic No shoirted outputs or power supply transistors.

Is there something im missing that would shut down power to that pin or?? Does IC have 5v out? If so, Q could be shutting down the amp due to a fault in the output stage.

I don't know if Q can be tested without lifting it. It's the only component that I can see that could be pulling the voltage detect down.

Q has 5v on base, so looks like it's being activated. All outputs are removed and none are shorted. Looks to me like q and q should pull down the 5v on q to shut it down. Couldn't understand how any of those protection circuits could work without some sort of output from the power supply. Figured it was mostly cause I am just learning and just dont know. Decided to download the owners manual to see if it displayed the fault if the amp is in protect mode. Turns out there is an output disable option in the menu.

Turns out the output was disabled. Who in their right mind puts a disable output option in an amplifier??? Oh well i guess ill put the output FETs back in tomorrow and see what happens. If it works the guy that was throwing it out will be pissed, ill have a new amp for my truck and learned a few things along the way. Thanks for your time Perry. Did you try disabling it again to confirm that the power supply was again disabled? I did, I was in awe that function was included. I did it like 5 times.
