Just had this exact issue with my BRZ2100D.1D and could not find anything wrong. Came across this thread in my search and took another look at the board.

Close examination revealed L1 and L3 had visible damage and L1 tested open. Replaced it and my amp is working tonight. Thank you! I was just about to give up on this and buy a new amp.

Just curious and more..I have 4pcs Ground Zero Plutonium 4000mk2 in repair and they look as similar as they could possibly be.
I dont have schematic for these GZs so Im thinking that perhaps I could use some Hifonics diagram

E: Similar with these Hifonics amps....

Click the image to open in full size.

Its a bit late here so I took the first one that came across
This one is a little prototyping version, powersupply control has been made with MIC4427 (the board was burned so badly so I had to figure out something ), few output FETs are missing and output driver board is still missing but you got the picture.....
