@sergdo,

Welcome to the Joule Thief forum, I will take a look at the links when I get time to do so, got my hands full down here just quietly.

@All,
I put my USB microscope to good work (at least it didn't get flooded) and I can verify Wayns remarks that some boards from the Kodak are very different, in fact even the parts which look the same are in fact different.
The case in point is the main transformers, they are made by  TCE which stands for Tokyo Coil Engineering, so far I have found 9KO49, So27, SKD49 SKD9, 1,
The SCR or transistors are D2470W, D2470N, D2470V, 5889 3G

I will try and send one at a time as I got a satellite problem here.
