Hello everyone,

here's my problem : I got what seems to be an original Silk Worm PCB by TECMO. Unfortunaly, it doesn't boot at all. Since the PCB is pretty clean, I decided to investigate and find a solution to fix it.

Unfortunaly, I have some wonderings about that PCB. Let me explain.

Here are 2 pictures - front and back - of my PCB.



Here are 2 pictures - front and back - of a working Silk Worm PCB.



As you can see, a small "daughter PCB" is missing on my version (right pictures), but on the other hand, there's an extra component (TECMO 5783 626) on my PCB (left pictures).

Moreover, fter searching a bit, I found this version on Yahoo Auction



This one is pretty similar to mine, including the extra component on the top.

So, here are my questions :

1) could someone confirm there are two versions of Silk Worm? (if you can send/link me pictures, that would be awesome)
2) if the answer is "yes", could someone tell me if my PCB is actually missing a part or not so I won't waste time looking for what doesn't work on it.

Thank you very much, and sorry for my bad english.
