I am finally getting around to building my ED from the first coop last year. The green LED on the board comes on, but I don't get any lights from the magicjack (my understanding is that magicjack lights are the benchmark for a functioning ED). In over 50 Lynx boards built, this is maybe the second one that I have experienced a problem with, so I hesitate to blame my assembly skills...although I have re-touched the solder joints. Both regulators get warm and the green LED comes on, but that is all I can tell is happening.
I have tried 5 different cables on 3 different computers and a linksys router and no combination gives me lights. I tried both jacks on the ED (I could not find which jack was the input anywhere
so I tried both). I flashed the ED PIC with and without power applied. I did check both square (50.0 & 8.0) components as suggested in another thread and found the following:
50.0 - 3.3V between 4 & 8 and 1.52V between 4 & 5.
8.0 - 3.3V between 4 & 8 and .99 between 4 & 5. Something else odd about this one is if I switched the probe leads on 4 & 5, I would not get -.99V (which is what I would expect since all the other things I have measured would come out the way), but I reads like -7.2V. Don't know if that is meaningful or not, but it seems odd based on my limited knowledge.
That is all I know to do at this time. I have attached pictures so they can be scrutinized. Before I assembled this board, I did notice that 3 of the pads seemed to be dull gray rather than gold like the rest of them. I thought maybe the solder pad was missing on those 3. I wish I had marked them, but I didn't. They did seem to solder so maybe it was just a color or reflection issue.
HELP!
TIA,

P.S. I had nice big pictures, but could not get them uploaded without shrinking them. Sorry I was under the limit.
