I've got S100 with no images. Both displays not woking. Both backlights are ok.
After changing flat cable - both displays works except backlight of colour display.

I found mistake ZD1 have wrong polarity on all cables which i have.
After repairing this fault - no backlight anyway.

I think cables have mistakes or missing connections in voltage generator circuit cos 3.xx volt (Backlight "IN") instead 9.xx volt.
3.xx volt - backligt off
9.xx volt - backlight on
May be somebody have schematic for flat cables for S100?
