) But it doesnt work it does not turn on at all (btw how do you do that?)
There are the following memory/flash in it:
29F800
29LV800 NEC D441000
I wonder whether the last is RAM (battery backuped?) and the other are for the software. Or are data saved in flash, as there is not battery inside, only the batteries for powering it all. Is it worth fixing?
But I found the problem: the fuse F601 was broken. I short-circuited with a peice of wirewrap and it works. The fuse is small SMD, with the text "12". My guess is that it is 120 mA, since the thing eats 3V 0.3W =3D 100mA. The local store offers 125mA replacement, that should be ok.
