no audio

Hi everyone. It's that time again.... Opened sunil case w/ v4 board to add audio amp. Removed audio pin 7 to the front input board and brought audio to amp from d16. Hooked internal speaker to amp and it worked great. Added front audio input and got buzzing/oscillations over audio. Turned off, removed front input, turned on, no audio. Took everything off amp and put audio back to board...nothing. changed q71, 72, and 73...nothing. Any ideas?? ThanksĀ
