Yeah - I know about these. They are all well aligned - as metioned, the 4 small IR waveguide dents with about 0.7mm diameter all slide in well into the holes in the PCB. You also need to excert a bit of force, when the back body is not put together, to keep the display and waveguides aligned.
The NN1001 would only light up the vertical (long) side of IR LEDs if they are not aligned, and not the horzontal (short) edge. Once there is alignment for that edge to apparently see the IR beams, then the vertical side lights up...
When looking with the IR camera at a shallow angle from the side with the IR receivers down to the IR waveguide with the LEDs, I can certainly see the shadow of my finger - ...
Also, if the enclosure is properly put together (which becomes less good, as some of the plastic indentent start to break with me pulling it apart and opening it so often), both edges are IR light constantly, indicating a good alignment.
Just no input is recognized on the PIN entry screen...
Does anyone know of a shop where kobo devices could be repaired - if they may have the circuit schematic accessible as to where to hook up for looking what the NN1001 reports?
