OK.
Now I have lifted off the flex and I have available the glass with 4 pads that seems to be done with a conductive paste.
The flex is instead gold finished.

Both sides need to be carefully cleaned because there is a strange white/transparent resin (probably a residuous of a conductive tape used for the original contact).

What I have noticed at the microscope is that all the 4 tracks are interrupted just at the edge before of the protective cover.
This is a clear sign of bad process from the toutchscreen manufacturer.
PHILIPS is for sure aware of this !!

Now I'm removing a bit the green isolation so that with a conductive paint I can restore all the 4 contacts.
Then I will bond again with a conductive glue the flex to the four pads on the glass.

I will let you know.

Bye
