Things went off track at post #91.
Did you test the output side FETs?
Did any of them read different from the others?

Find the end of C2091 that's connected to ground.
Connect a jumper from pin 8 of U2000 to the ground end of C2091.
Will the amp power up with the B+ connected?

Yes, with it jumped.
Yes. powering it up normally.
I wanted to make sure pin 8 was grounded.
Do you see a pulse of DC on the speaker output as you power the amp up? You'll need to be watching the scope from before applying remote. Then for 5 seconds after.

Sorry obvious questions. There is 0.14v on pin 8 of u2000
DISREGARD THIS POST ..This is with it not jumped...
Does it still go into protect with pin 8 grounded?
If you connect a load across the speaker terminals, does that bring it down to 0v?

Yes protect with pin 8 grounded. yes voltage goes to 0 with load.
Why when I put voltage to pin 2 of u101 does it power? ,is that bad to do?
It happend by accident when I shorted pin 2 and 3 of u101 with probe.
Just a video of what it's doing.
Videos are generally useless for repair work.
What's the PS driver board number in this amp? It likely starts with 1405-...

I want their marked value. Measuring the resistance with the parts in the board could be reading other parts as well.
