I am here to see if I can fix my Infinity PS-12 sub.

Re: Infinity PS-12 Powered Subwoofer Fired Amplifier



My sub has problem switching from red to green. I repalced most of the capacitors although they all looked good.
C2/12/35/37/39/41/78.
I also replaced Q2 with 2N5550 equivalent and Q3 with 2N5401 since I could find the original parts. Are these the right ones?

My sub switched to green now. But no sound when I connect to the amp. If I played from my phone, I'd get sounds.
What other parts I need to replace. Also, C71/72/73/74 still have 0V....
