iPad 4 Wi-Fi: Touch screen not working after replacement, am I missing something?

Wed, 06 Apr 2022 15:06:09 -0700

My front glass was smashed and the touchscreen wasnt working- not suprising. But now I replaced the front panel and no touchscreen. Actually I'm at the stage of testing to make sure new one off ebay works. lcd works fine as does home button. This is the first time ive replaced a screen on ipad and I feel like it may be something very obvious. I havent removed the glass protector and I didnt clean/ scrape offthe black foamish looking stuff around lcd. Is there something simple or otherwise that could make the touchscreen not respond?

iPad 4 Wi-Fi: Does “blank home button” mean home button included or just a space?

Wed, 25 Sep 2019 11:47:44 -0700

The 4th gen digitizer KIT says it has a “blank home button.” Does that mean it comes with a new home button or do I need a new one? The screen is cracked and the home button isn’t working.

iPad 4 GSM: Ipad 4 not charging and not starting

Sun, 09 Sep 2018 10:14:05 -0700

Dear tech-people,

my Ipad 4's battery has reached 0% two days ago. As usual I attached it to the original charger (with non-original cable) but it would neither charge anything (just stay as in the attached picture) or boot. After inserting the cable and after pressing the power button the attached picture appears on the screen for two seconds but nothing else. It stayed on the charger for around 24h now without any changes.

I have already researched a little and have tried a second cable, charging dock and cleaned the lighting adapter (nothing noticable came out). I also tried the different combinations of pressing the power and home button, but the Ipad would just stay in the state as in the picture.

I have run over this tutorial from 2012: Ipad Dock connector no longer working

Does anyone know if this procedure would be applicable to the Ipad 4 too? Any other ideas?

Thank you a lot for your help!

Best regards

iPad 4: Ipad charges when off but won't charge when booted up

Mon, 29 Jan 2024 16:10:54 -0700

Hi fellow repair people.

I have stumbled on a puzzling situation after replacing a battery on an ipad 4 A1458

The ipad seems to charge perfectly fine while off but when it is booted into the OS it doesn't charge but it is recognized by both Itunes and my laptop. It also seems to have a hard time recognizing the home button.

Any tips, tricks or insight into the root problem would be greatly appreciated.

Only a small section of my iPad4 screen works (i.e. accepts input). The screen is not cracked. If I understand correctly, there's the Touch Screen Digitizer and the LCD lies behind it. Is that correct? Which part would I need? Thank you!

iPad 4 Wi-Fi: Toothpaste in headphone jack, no sound from speaker :/

Mon, 16 Mar 2020 20:04:19 -0700

I got toothpaste in my headphone jack (road warrior woes) I cleaned it out with a syringe and distilled water then rubbing alcohol. But now the device thinks there are headphones plugged in.

I have no headphones plugged in, however the volume display says 'Headphones' when I use the volume buttons.

Anyone taken apart a headphone jack on one of these that can tell me how it senses the presence of headphones? Contact switch?

iPad 4 Wi-Fi: Glass shards in Logic board connector?

Wed, 05 Feb 2020 11:36:05 -0700

I have recently removed a badly-shattered iPad 4 screen, and installed a replacement.

About 5/6ths of the way down the screen, there is an (invisible) horizontal band, running the entire width of the screen, that is completely unresponsive to touch. I have tried two different screens, with the same result.

On close inspection of the sockets where the digitiser ribbon connects with the logic board, I noticed one was slightly cracked and raised, suggesting a stray piece of glass (or other debris) has managed to get stuck in there. There is also evidence of a deformation of the ribbon end, resulting from when I pushed the ribbon into its socket.

Does anyone have any experience of this and could suggest the best way of cleaning out the socket? Should I use compressed air, or isopropyl alcohol, or is there a better method?

All suggestions gratefully received.

iPad 4 Wi-Fi: Half of the touch screen not working

iPad 4 with only 1/2 of the touch screen working. I’ve replaced the digitizer with 2 working touch screens and the problem remains.

Under microscope all the ribbon connections look fine with no signs of damage or lifting.

Is it time to reball the touch ic?

iPad 4: Ipad 4 battery stuck at 1% after Battery replacement

Wed, 18 Sep 2019 04:10:29 -0700

Hi,

I took out my iPad 4 after a year or so to find that the battery had swollen to an extent that it had separated the top right bit of screen off the body.

I got a replacement battery and tried to replace it myself., followed the iFixit guide for it which was great. The device ran fine till the battery drained till 1% after which it turned off . While charging , the device does show the lightning symbol, but the charge percentage does not increase. The

The Apple ipad charger/cable are known and working.

I’ve tried the following so far:

-Re-seated the logic board to make sure the pins were making good contact with the battery

-Checked the voltage across the +/- of the replacement battery which showed 3.12V, does this mean that this battery is bad or is it just discharged?

-Soft Reset(Home + Power)

-Charging while powered off

Is there anything else I can check to identify the root cause? I was considering the following:

-Will putting the ipad into DFU help?

-How can i identify a bad Tristar/U2 IC chip?

-Is it possible that the swelling up off the old battery damaged something else in the circuit?
