touch screen not working at all
Hi everybody
I inherited a nice Ipad Air spacial gray to repair. It looks great! the only problem is that the Touch screen is not responding at all. I removed the digitizer and I can say that it's the original one! never been changed as it was really a long and hard task even with my hot air station. (don't know which tape Apple uses but it's a good one!).
As I have a touch screen for the same model in reserve I changed it although I was almost sure of the result. And I was not deceived: still the same issue!
So it's a problem directly linked to the motherboard. Doing some request on Google I found the possibility that it could involve 2 quartz located on the mainboard just near the 2 digitizer connectors (why 2? one for vertical move & one for horizontal?)
Before I eventually buy a pair of these one did somebody encountered the same issue and how it was solved?
Thanks for your answers
Pat

Hi
I finaly came back to this Ipad issue and decided to remove the Emi shield that protects the 2 Broadcom touch screen controllers . Then I tried to use my hot air solder with to apply hot air (250°) for 5 minutes.
Then after all got cold I reassembled the LCD + Touch screen and believe it or not but it worked.... for some hours only ! :(.
Strange thing: all looks like the hot air put back to life these controllers but only for a short while!
I tried again the day after , but this time , it was unsuccessful.
Probably this proves that these controllers have to be changed. I don't know exactly how they work (why 2 controllers? )
If somebody experienced such issue, I would be grateful to have some more info

You have tried a reset after installation correct? Motherboards dont have a history of malfunctioning especially with ipads?

You're right that I was not precise enough.
Yes I did a reset but with no change.
It is also reported by its former proprietary that it doesn't anymore connect to WIFI.
To be precise it was reported that the first issue was the loss of any WIFI signal and shortly after the loss of touch screen capability. (if I believe him, but no reason why I shouldn't)).
I don't think there could be a common explanation with these 2 issues, but maybe I am wrong (IC power chip???)
