Won't power on and smells burnt after attempting to change the screen

Hello I was changing the screen on an iPhone XS max. Like a dumb *** I forgot to unhook the batteries and now the phone will not turn on and it smells the burnt. I really want to fix this phone as I'm trying to do this to make extra money and this one belongs to someone else. I understand it may take some fine soldering and I'm prepared to do that. I just need help troubleshooting to find exactly what part to change. From what I figured out so far I'm thinking I fried the power ic. Am I even close? Can someone with some expertise in the field please help? I really appreciate any input Thanks and have a great day!

Hello again everyone.

I decided to try the screen on this phone again and guess what. It worked! Everything works as it should. I have no idea what went wrong but this thing smelled bad and would not even power on a week ago. It's just been sitting on the shelf and decided to come back to life. I'm glad I didn't send it off to get the motherboard repaired for $300. Anyway thanks to everyone who did respond to my question

That’s good news! I would go buy a lottery ticket if I were you.

Yes Chris it is very good news since instead of having to pay out of my own pocket to get the lady's phone fixed or buying it from her I ended up making a profit as planned. She was ecstatic and so was I. I may grab a lottery ticket but I think that payment for the repair was my scratch off.

I just wish I knew exactly what happened and why it smelled and wouldn't power on and then decided to work perfectly after sitting for a week. I'm sure if the right person sees this they'll chime in with an answer.

If you want the communities help diagnosing your phones problem, you will need the following equipment.

·         Schematics diagram for the phone.

·         Board view software.

·         Multimeter.

·         Microscope.

These are only for diagnosing the problem. You will need more equipment for the repair.

I recommend trying another screen first in case the damage was only applied to the screen.

Thanks. I am working on getting that equipment. I will have it all soon as well as what I need for repair. Changing a screen is one thing but I want to get deeper into it. I just need a little guidance and practice.

Did you use an aftermarket LCD screen assembly instead of the original design OLED assembly? If so, then a crease in the screen will short main voltage to ground and burn up the display connector. I did a video on this a few months ago. https://www.youtube.com/watch?v=D_PnL0KK...

I sure did use an aftermarket LCD assembly. I'll be sure to watch that video. Thanks.

さんによる

I just watched your video. Nice work. I haven't done any repairs of this nature yet but I do have some knowledge of electronics and soldering so I won't let that stop me from trying. I am starting to gather tools and supplies so I can start practicing. I have plenty of devices to practice on so no problem there. I really appreciate the help and I'm glad I found this forum. Thanks again everyone.

I believe you fried your motherboard. Hate to say it but there’s not much you can do.

The mother board has not been fried. A component on the logic board or screen has suffered electrical damage. The component should be replaceable.

I wish you luck then, good sir!

This answer is wrong.

さんによる

I mean, it’s not that it’s wrong. It’s not specific enough. I’ve been around burnt components before.

さんによる

You're implying that you can kill an iPhone XSMax logic board by some kind of transient battery short, and that it is not repairable---that's wrong. You're getting pushback on this from the repair community because the OP marked this as "chosen solution" which could mislead a lot of people. This phone is repairable, although it may take a trip to your local iPhone logic board microsolderer.
