Can I repair the display connector pins?

I was replacing my whole display unit, including home button front camera and speaker. The first time I turned on my phone after the operation, the screen and the front camera worked great. But the home button did not. My phone displayed the "touch ID not recognized" or something like that. So I took it apart again to see if I had not secured the connector to the pins. After the second operation I turned it back on, but this time the screen did not turn on. However, the phone still worked, as I plugged it in and it vibrated and I flicked the side switch and it vibrated. I did some troubleshooting and it seems that I may have eroded a pin off the connector on the phone side. I took out my science kid magnifying glass, and I also used another phone to magnify the image. I adjusted the contrast, and saw a dark spot in the place of the assumed broken pin. If it is truly broken, is there a way to repair it?

Pictures of close up with polar contrast settings on the iphone X. I used a magnifying glass then used the magnifying app.

It’s possible to repair but your best bet is to add a picture to your post so we can actually take a look.

Turns out it was just a bit of dirt or corrosion. A lil bit of cleaning alcohol and a cotton swab did the trick. Thanks for help.

Hi Lugar,

It is indeed possible to fix; generally that involves replacing the FPC connector on the logic board. That's done with a hot air station and requires a fair amount of expertise in microsoldering. I've been soldering circuit boards for 30 years and I wouldn't take this on myself, especially without professional level equipment.

If that's what your phone requires as a fix, you'll need to find a (hopefully local) repair shop that is experienced with that kind of repair. They should be able to locate a replacement connector and do the job for you. It's important that they guarantee their work and are willing to fix any incidental issues that may come up in the course of their repair.

So please do post pictures; the best resolution and lighting you can get will help immensely and we'll see if we can confirm what your next step should be.

You never mentioned you disconnected the battery at all. Also you said you're replacing the home button, why? That's why you're getting the message. Use the original home button unless it's faulty.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@strongbow no i am replacing the whole screen including home button and front camera. so that means the home button is attached to the new screen as well as the front camera. Should I have disconnected the battery?

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@lugar Yes, as the guide here (iPhone SE 2020 Screen Replacement) on step 16/17 says, the very first thing you should do after gaining access to the internals is to disconnect the battery. Before even disconnecting the screen itself. (You'll see similar advice in practically every guide on this website; disconnect the battery ASAP in every repair job.)

As far as the home button, you should have migrated your old home button from the old screen to the new screen, if at all possible. If you instead *replace* the home button, you will lose Touch ID forever, until and unless you can replace back the original again.

For your photos, it appears you do have a bent or broken 5th pin from the right on the top side of the top connector of your photo. There *might* be enough contact material left for it to not matter, but I do think you're right in that it is the cause of your screen problems.

crwdns2934271:0crwdnd2934271:0crwdne2934271:0

@lugar For your original question, is it possible to replace this connector? The answer is *yes*, but it is extremely difficult and specialized work that requires much experience and very high-end equipment to get right. Most of us here do not have that ability, and I doubt you do (nothing personal) or you wouldn't even be asking here.

For reference, here is a video displaying exactly how to do this with a good explanation: https://www.youtube.com/watch?v=MU3FABXN...

Generally, these board level repairs will cost you more from a trained professional than the device is worth, so it is generally only something someone does if the device has important data on it that is not available elsewhere.
