Apparently you didn't leave the quad in pause long enough (oh, about 5 seconds?) *impish grin*

Woot!

I am glad you got it! I haven't found any time to actually look at the schematic yet... last minute corrections to my IMS2009 paper.

Awesome!

Part of me wants to go figure out what happened to the analog audio I/O (again, ages ago), and part of me says noooooooooo! *giggle*

Yay! Troubleshooting logic is great fun...glad to see you nailed it! ^_^

I'd suspect all those road miles probably contributed...was it an actual trace fracture or a bad solder?

I couldn't quite make that out. It went from a through-hole pad, to a via, about 3" up the board directly into a new pad. The short hop to the via was good, but the via to the other pad wasn't. Lots of components in the way preventing a good inspection of the other trace. It still didn't work after reflowing the pads, so it must have been somewhere in the trace.

It seems really unlikely to me that a bad trace would just develop, but there are certainly folks with way more exposure to this sorta stuff than I have!

Working out the logic was a great deal of fun, especially programming triggers in the analyzer to ensure my samples always started at line one in the VBI (Sony was kind enough to document the digital data structure). I imagine I'd have been utterly sunk without the analyzer. Now I'm really wanting another DSO card for that HP frame. 4 channels of 500Mhz 2GS/s would be spiffykeen!

It's obviously time to go back to 2" analog quads!

All kidding aside, well done! And here I was feeling all accomplished for taking apart and then replacing the garbage disposal this weekend. =)

Well done! :) I have never really been able to wrap my brain around electronics of more than a pretty low level of complexity (I'm more of a software type), so I'm impressed. ^.^

(BTW, s/pour/pore/ - that is just a pet peeve of mine ;>)

Wow, I'm usually rather sensitive to such things as well. Corrected!
