Repaired but touch screen not working
Hello all, and thanks for this great resource.
My e-pl7’s screen cracked. I ordered a replacement from aliexpress and followed the guide and it comes on now, but the touch screen doesn’t work. I have taken it apart and re-attached it several times.
During my repair, I think the ribbon ZIF connector may have been ‘truncated’ by a few pins when it was dropped, but as far as I know that’s just to secure the cable, not conduct signal. I don’t know what else could be the problem, aside from a faulty replacement part or invisible damage during the break/install. There is what looks like a grounding pin left over that @tgaines also could not find , but there were actually a few differences between the original and replacement part so I’m a bit lost as to how to restore the touch function.
The camera works without the touch screen, but it’s very useful for spot focus, focus tracking, and zooming, among other things.
