iPad Air Touchscreen is not responding at all

I have bought an defectiv ipad Air 32 GB.

The Digitizer of the device does not responding at all.

I have already done mutliple Hard resets and flashed the newest Firmware.

But nothing changes.

The iPad has no scratches, no dents, the Glas is not broken or anything else, no water damage, everything original Parts.

The iPad looks like brand new.

So, before i am trying to change the digitizer, is there any possible solution for my problem?

Is it possible, that the logicboard has a problem? If yes, which part of the logicboard is responsible for the Digitizer?

Update

I have have changed the digitizer against a new one, but it won't work also

回答此问题 我也有这个问题

这是一个好问题吗?

Hi christian,

It sounds as if it is a board problem. could be the touch controller ic. the picture i have linked shows whats under the little metal cover on the logic board behind the touch connector. i would suggest having a look at those components and see if anything is out of the ordinary and clean with some ipa.

I have heated up the controller ic with an hot air gun, without removing the emi shield. For now, it helps. The digitizer works again. I hope, this will fix my problem for an long time.

Hi christian

Same issue for me. I found your topic. did your fix worked for times?

It's very difficult to remove this emi metal shield as it's very near to others components (connectors...)

Which temperature did you use with your hot air soldering stataion? (250° ..)

Thanks

The digitizer is fine but not functioning. It is in perfect shape. I also did hard resets and update the OS with no luck.I am willing to take it apart again, but what shouId I be looking to do?

check connections on the chip?

It's a pitty not to see anything about this kind of issue. I didn't find any publication on youtube. This is not the most common issue for Ipad , but it's not so rare, especially on Ipad air models. The temptation is to say that it might be the 2 broadcom touch chip controllers, but it also might be peripheral components.

i have the same problem nothing working at all on a iPad air 1st gen i have tried four different digitisers and re soldered the connectors but still nothing this looks like its a common problem in what i am looking on here i think lewis might be right so now i am going to see if it can be sorted by heating them broadcom chips up and see if that will work if it do's i will let you guys know here.
