On my touch this button is in the center of the screen, about one inch from the bottom.
Touch screen failure can be caused by dirt (outside in the display borders, and inside the device itself). It's also possible that the board itself is not mounted/aligned properly.
Sometimes it's just a failure of the infrared emitters/sensors, I've bought a used Glo with perfect display but no touch whatsoever. I suspect it's the board itself in this case, but I can't test it... haven't had luck on Ebay lately, people just bid too much for broken stuff.  |
Turns out that you are right - it just wasn't mounted tightly and when I made some adjustments the touch functionality came right back. So this eBay screen from a "broken" Kobo touch does indeed work just fine. Now my original battery seems to be acting up (claiming 100% but not holding a charge) so we'll see if that needs replacing too. Unfortunately the battery that came with the reader has a different type of connector, so I can't try it out.
