Exclamation Help! Need Circuit details of TEAC/ESOTERIC DAC D-500

My D-500 broken long time ago. At recent I decided to open the cover to check out. Unfortunately, when I screw off Audio PCB the connect cable of Digital PCB was broken. When I pulled out flat cable (AWM 2896) I found connect points peel off. Therefore, I went to electronic shop bought new flat cable to replace. Here come problems:
The new flat cable spec seems won't fit slot on Digital PCB. Need cut off the edge of cable. The Audio PCB doesn't have a slot like Digital PCB. It's soldering by manual. So I have to cutted cable in half and peel off each isolation. When I insert cable to slot and use Digital Multi-Meter to check every point of connector on Digital PCB is link to peel of side. A new problem rise-up! My Multi-Meter shows short ciucuit between 2 points. Means if I manual soldering cable on Audio PCB will cause big disaster if I turn on power.
I pulled off cable and compare to previous cable found the gap of connect point are differences in between. So, that's why short circuit happen.
Now, I need to figure out the circuit between Digital PCB (Connect P106) Click the image to open in full size. and J1(On Audio PCB) Click the image to open in full size. Maybe just simple drawing to helping me. At least I won't solder wrong connection. I would be appreciate anyone who can help me.

I have TEAC D-500 DAC and found problem at the left channel of the audio output. May I have a complete service manual for repairing since the attached circuit diagrams are so small and unable to read? Thank you and please have a nice day.
