Hi,
I have a Bluesound P300 and it has no power. Only pulse noise coming from speaker so I checked the circuit board and replaced 4 capacitors but problem is still there. The circuit board is, SP DDFA AMP BOARD which is three channels amp. So please advice me what and how should I diagnose and chance.? Thank you.

Throw it in the trash and purchase a new one.
Top-notch Digital-Amps are relatively cheap.
What are your requirements for an Amp ?

Thank you for your reply LowQCab. As I posted, that device is like a Sonos 5 (but it produce HiRes music) so I can use USB, Ethernet,Bluetooth,etc. It has only three speakers which are LHS and RHS tweeters and one Mid range/ Bass driver. So it has three channels amp. I knew I can use other amp DAC etc but just wonder if I can diagnose and fix it by myself and if I need to replace cheap item like Capacitors resister etc I want to fix. Otherwise I won't. Thank you once again.
