@hatteras Nice posts! Would you know what wavelength the IR LEDs use. I couldn't find it in the docs from further reader.

I have already fixed the screen of my Kobo Aura H2O. But the touchscreen had a problem with a column on the left. 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.

EDIT: It's working again!
