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

lu64319 · 10th April 2010, 03:52 AM

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)

and J1(On Audio PCB)

Maybe just simple drawing to helping me. At least I won't solder wrong connection.

I would be appreciate anyone who can help me.
