iPhone 4: Power and Lock Button Stuck, Requires Heavy Pressure

Fri, 09 Sep 2016 06:52:07 -0700

This is a first-run iPhone 4 that's in otherwise perfect condition.

Last night, the power and lock button became extremely difficult to push. I assume that there is some debris or that the button itself no longer presses (an issue I've noticed with Mid-2009/2010 MacBook trackpads as well).

I do not know whether or not there is a physical button that is being pressed, part IF182-004-1 shows a button with a level that I assume is actually pressing a real button.

I have removed the back of my iPhone, but I'd like some more information before I remove the logic board and void the warranty. The replacement guides don't have any information about this button.

iPhone 4: My iPhone says its disabled

Tue, 15 Aug 2023 05:20:47 -0700

My Iphone 4 has on the screen: iphone is disabled please try again in 22,652,900 minutes.

I have tried to restore it with iTunes and even reset it but it then asks me for the passcode to be entered in on the device and I cant because when I go to unlock the screen it only goes to emergency calls only it doesn't give me any options to enter a passcode and I don't know what the passcode is as I never put one on there or if I did I don't know what it is, Ive never had to enter an unlock code when I turn the phone on so I am unsure of this. PLEASE HELP

Hello, I have a problem with my iphone 5 CDMA. I tore my Audio control & Power button flex cable, and I just put it back together, and now I have no service...so I entered my phone into DFU mode and now it can't recover. It gets to a little bit half way and then on iTunes I get Error (3)??? Do I have to get a new cable or what? Please help I've replaced the power button already.

iPhone 6: Why does my phone turn off when unplugged from charger?

Fri, 09 Sep 2022 06:42:57 -0700

I have an iPhone 6 that has been repaired once (change of a broken screen and some chip).

It's stuck on 1%and doesn't go any higher.

When I unplug the charger it turns off even if it's been left all night.

It keeps switching on and off.

As long as it's in the charger it works fine.

It doesn't switch on if I plug it in to my computer it keeps showing the apple logo then a black screen on and on.

I at least wanted to back it up in case of a reset.

Sometimes when it switches on it gives 100% but then shuts down quickly even if plugged in.

I get the sign that it's charging but it doesn't increase.

iPhone 5s: Why would the home button work, but not Touch ID?

Tue, 28 May 2019 23:35:31 -0700

I own a small Apple repair business, and have done a large number of iPhone screen repairs... everything from the iPhone 3G up to the iPhone 5S. I have only done a handful of 5S repairs thus far though, and haven't had any issues until now. The problem I'm having with a customer's phone is with Touch ID. Now, I'm fully aware that the home button flex cable that ships with a 5S is unique to that particular phone, and cannot be replaced while still preserving Touch ID functionality. Repairs don't generally make me nervous anymore, but 5S repairs do because of this....so, I'm extremely careful.

With this particular 5S, I successfully replaced the screen, only to discover that the part was faulty (defective digitizer). However, I know that Touch ID was functioning after this first screen was installed because I did test. I then installed another new part, everything went well and the part tested fine this time. I did not specifically test Touch ID functionality, but I do know that the home button was working. I've always figured that if the home button is working, then Touch ID is going to function.

The customer called me today to let me know that Touch ID is indeed not functioning at all, but the home button is. This seems very strange to me, and the only thing I can think of is that I didn't get the home button flex cable connector properly seated when I put everything back together. I will have a chance to open the phone back up tomorrow, but in the mean time I was trying to do a little research on potential causes for this as well as potential fixes. Of course, my hope is that removing the bracket, disconnecting, and reconnecting the flex cable will do the trick. Of course, unfortunately the simple solution isn't always the answer.

Numerous searches on here, Google, and other websites have turned up nothing with regards to this problem. Everything I can find relates to the unique relationship between the original home button cable and the motherboard, but that's it. I did find one person that had Touch ID functionality, but no home button functionality. Similar but still different enough to not be too helpful.

So...any ideas out there? Has anyone else come across this issue? Thanks in advance for any help!

iPhone X: Face ID not working after water exposure

Sun, 11 Jun 2023 21:00:58 -0700

I waded into some water (depth maybe 30cm above iPhone level), incorrectly assuming my phone would be fine. The phone shut off, and I just let it sit and dry out for the next few days. After turning it back on, the phone got very hot so I turned it off again.

After a week, it no longer got hot but got an occasional green vertical line. Again, phone off, and after half a week no more issues.

All functions of the phone now work, but FaceID does not work anymore. I took it to the Apple store, and whilst they said that all it would take would be to reseat the camera unit (or something along those lines), they would not work on it due to evidence of water damage.

Any insight or advice would be appreciated, if its an easy fix id like to get in there and sort it out! After all, FaceID is half the reason I love the new phone.

Cheers

iPhone 6s: I dropped my phone in water and it wont turn on...?

Sat, 20 Jan 2024 10:38:00 -0700

Yesterday i was on a dock where i fell into salt water for about 10 seconds with my phone in my back pocket. the whole bottom half of the phone was in the water but only for a little. i took it out of the water and the lock screen was working fine. i then put it away and biked home where it would not turn on. after a couple minutes it started turning on with the apple sign and the screen would go white with weird lines. i sucked out the water from the charger and headphone jack with my mouth and lots of saltwater came out which is when i continued to put it in a bag or rice. it has been in the rice for 12 hours and this morning i took it out but it still will not turn on or do anything. it is now back in the rice and idk what to do. i just got this phone.

iPhone 5c: iPhone 5c Proximity Sensor Not Working After Screen Replacement

Thu, 12 Jan 2017 04:36:55 -0700

After changing the screen on an iPhone 5c the proximity sensor does not work. After noticing it did not work I took the phone back apart and repositioned the front camera and proximity sensor. After a hard reset it still does not work. The front camera flex cable has no tears so I assume the problem lies on either the screen not allowing enough light or ... That's why I post this question on this forum. Is there any simple troubleshoot like before on the iPhone 4/4s? Is there anything I'm missing that is simply over looked? I examined the original apple screen around the proximity sensor and it matched my replacement screen. I am simply asking for any tricks or tips from others who have encountered this problem..

Thanks in advance

iPhone 6s Plus: Half screen darker than other

Mon, 26 Dec 2022 11:31:27 -0700

Bear in mind this doesn't have to do with lines. It's the brightness of the screen, darker on one side than another, and this is on a new screen.

This is a new screen, and for some reason it's darker too left, but more dark on almost all the left side. I've never had this happen before. Has anyone else seen this or know why?

iPhone 5c: iPhone 5c Black Screen After Replacement?

Wed, 27 Feb 2019 04:44:27 -0700

I just finished replacing an iphone 5c screen, and checked to see if it would power on before I put the screen back fully into place. The apple logo came up and the phone powered on normally, so I shut it off and put the screen fully into place. However, the backlight seems to come on but the screen remains black with no apple logo. It still responds to charge still and vibrates but the lcd remains black. The connectors look normal and do not appear damaged in any way. I have tried hard resets and taken the phone apart several times with no avail. I have also tried other screens which produce the same result but work in other phones. I fear this may be a short in the logic board, and if it is such, is there any fix besides completely replacing the logic board?
