iPhone repair to a motherboard (Logic board) that has a faulty touch screen. The phone is a 4gb jailbroken iphone with Cydia installed. Symptoms are areas of the touch screen not responding. Contact me on modmyi.com if you need service or help. User name “one1”. FREE estimates and diagnostics. I also buy dead iPhones that are too far damaged for repair.
clearly you know a lot fsob. the thread looks like you’re dead. could you go into a little more depth about the probing and what the oscilloscope is telling you? is there a quick way to tell if the motherboard is ruined (i.e. from water damage). Also, what would the repair process be if you found a problem while probing, re-soldering? please educate us more for the beginner.
Hi,
I have an iPhone 3G that blew up because I bought a cheap crappy iPhone charger on eBay. :@ I want to sue the seller sooo bad ! :@ There were sparks flying when I plugged in the wall charger & my iPhone blew up & now is dead. I bought a new OEM charging port but it didn’t work. New battery didn’t work. I’m assuming it’s the motherboard that’s been blown up too & is dead now. Is there any way I can fix it ? Or is it damaged beyond repair ? Thanks ! 🙂
Can you make a video on how to remove the motherboard on iPhone 2G???
@T1nn3r Maybe you’re just stupid?
could you use a multimeter and if so what setting would I put it on?
do you do repairs? such as replacing the digitzer connection on the motherboard. I have the part, but i don’t have the skills to solder it in.
this vid is so senseless..
because 99% of viewer who would do this would make the phone more broken..
and over 99% dont have the necessary equipment to do it..
also u need to know what u do.. and on the vid u cant clearly see what u exactly do..
hello
do you know how i can repair an iphone 2g which is not loading if i plug in the cable? it seems to load but as i plug off the cable the display disappears. i cant open up the iphone to the main screen. and it wont power on without a cable. i have already soldered a new battery but it didnt help. i think theres a fuse blown on the comboard. but which one?
@BrendeneoTV yup allllll the way man.
Hey dude is the brightness all the way up?
ok i got 1 problem, my iphone LCD screen works but its dark as fuck…like i can hear the sound of my apps etc, but the only way i can see the screen is if im under bright sunlight….whats wrong with it? it was in the washer by accident.
PCB working without power supply or battery? man, wasn’t that just the noise scope showed you? 😉
I was wondering if you sell parts and if i unplugged the little wires in the wrong order, like they all unplugged at once. did that ruin my phone .
i’am talking about the numbered wires on 3gs.
thank you ahead of time
So, did you have any luck? Did you find the line to the dead band? Was there a way to fix it? I suspected a corroded line that was shorted or a contact that separated from the glass on the touch screen sensor. I didn’t have much luck cleaning or testing the connector contacts.
I’ve read all sorts of stuff about possible software fixes, but most of them did not make sense to me and I suspected it was just coincidence and luck.
what happened to the iphone and what caused it?
So what do you next? After you found the bad plug?
It’s a Techtronix 442. Fortunately when probing you don’t need much. If I needed to know the frequency output of the comm board I’d need to use a bigger scope such as the one I keep at the office. I leave this one laying around because it traces very good and can be found for cheap anywhere. A very expendable scope. If you blow it up probing, you’re not out much of anything.
damn where can i get thet machine lol
