Well,
Last month my NExus 7 2013 32 GB (wifi) had stopped working - it just freezed and after reboot got very hot and stopped at google logo. After one week of fighting , going through the depths of internet: xda, google & other sites I`ve decided to replace motherboard as it seems the emmc 32 gb memory got broken by itself. I`ve received new motherboard (with 16 GB emmc this time as it was 40USD instead of 80USD for 32 gb version) and installed correctly with a little help of ifixit teardown and youtubes.
It booted fine, all the buttons are working, but now I got this strange touch issue: the digitizer dont recognise my touch in a certain part of the screen - I`d say its 3mm wide line a little down from the top of the screen when in portrait mode.
I tought I did something wrong when putting parts together so I replaced new ribbons which came with new motherboard for the old ribbons from old motherboard. No luck here - this didnt resolve the problem. I also did install multi-touch-fix I came up here on xda some years ago (boot-ts12-lock.img worked for me fine). This also didnt change anything.
When I was replacing the motherboard I did it very carefully and I`m sure I didnt break anything - also I`m sure that before my old motherboard went down, the touch was working very well.
If anybody knows what I could do to save my little precious nexus from throwing to garbage, please help.
I`ve attached a screenshot from touch tester for all of You to see what I mean. Please note that some minor touch registered on this non-working part of screen are most probably some ghost touch as when I move my finger over that part of the screen it doesnt record anything.
