I have the same problem with my Kobo Aura H2O. It turned out to be a missing infrared diode (IR LED side SMD). Still trying to pin down what wavelength the photodiode receivers use. Apparently, 850 and 940nm .

Unfortunately, the size of the diodes has changed over the years. My old pocketbook and Kobo Aura HD use a larger IR LED, otherwise I could have soldered that one onto my H2O....probably, still going to try that.
