Pioneer gm 3400 no audio

Hi all, I have a Pioneer Gm 3400 which powers on but makes no audio from the speaker outputs.

The input gain board CNP2608-D had 4 badly leaking capacitors C308, C307, C305 and C305 which I replaced
but still no audio.

IC302 and IC303 have no audio on pins 5 and 6.



Any help appreciated
