- This time around, I was faced with a particular challenge: an iPhone XS that wouldn't charge or turn on. When connected to my lab source, the power displayed was exceptionally low, clearly indicating a problem.
My first step was to disassemble the device. This involved removing the torx screws at the bottom of the chassis and using a suction cup to create an opening. With the help of a plastic pick, I cut through the adhesive and was able to access the inside of the iPhone.

Once inside, I removed the screws and the protection plate, managing to remove the motherboard. This is where visual inspection becomes essential. I watched the junction of the plates closely and used a 90x Amscope microscope to examine more closely. I noticed that the foam protection had been exposed to high temperatures, and there was flux on the FPC connector, indicating that the device had been tampered with previously.

I continued my inspection and found a damaged plastic connector, and signs of tampering at the junction of the boards. I wrote down each anomaly as I proceeded to remove the foam protection from the connectors. To separate the plates, I used a machine that works at 220ºC and was careful to avoid excessive force during the process.
After removing the top layer, I cooled the plates with a computer fan. With the help of the microscope, I looked for possible failures in the motherboard and observed that the thermal paste was not applied correctly. In view of overheating damage, I used a thermal camera to analyze the board and detected intermittent consumption in a specific area.
I then applied some flux and warmed the area, followed by a thorough cleaning with rubbing alcohol. I connected side A to a lab source to see what happened, and luckily, I was able to get an image on the screen. I used the iSocket tool to join the two boards without soldering them together to make it easier to connect the display to the motherboard.
I had identified and solved the problems, and after connecting all the flexes, I was able to turn on the device. I did some additional checking, scrambling the IC, joining two boards together, and assembling the device. To finish, I checked if I had network, wifi and bluetooth working correctly.
This repair process may seem complex, but with the right tools and a good understanding of each step, it can be done effectively. Patience, precision and attention to detail are essential in this job. I am proud to be able to share this tutorial with all of you, and I hope you find it useful and educational. Until the next video. See you later!

Magistral, a otro nivel felicitaciones leonardo.....
Gracias por sus aportes.
A la orden Manuel. Un saludo!
Hola Leo, en este caso lo solucionaste con solo un reflujo?
Hola Emerson, siempre le hacemos un reballing. Reflow le hacemos para verificar si el fallo esta allí. Para no tardar mucho con el video no hemos grabado todo el proceso. Un saludo!
Que bueno, otro video más de reparaciones de MovilOne.
