if youre testing this amp on low/limited current supply then it might have a pretection circuit that checks if theres enough current available from source.
you can scope the any rail and pulse the remote and it should build with each pulse until its tricked into thinking theres enough current and will turn on, or, assuming you have done all necessary checks, just turn up the current and see what happends

that is exactly what i have done. i turned up the current to allow it to have all it needs. still the on and off until the the rail voltage slowly climbs.
so i replaced it with one i had available. 10uf 250v. i still can not find the reason for the start up issue. do you know how to disable the protection?
ok s ok i found out that it has something to do with the protection circuit on the the daughter board. If i solder a bridge c11 and q10. the amplifier powers right up.
Anyone know about the protection curcuits in these amps? How to disable it completely for testing.
The amplifier will start up with full clean audio, then it goes distortion. The start up is also an issue. the protection circuit or the muting circuit is failed in someway.

Try removing the equivalent of QS4 on the following diagram.
