We've discovered a "signature fault" in the iPhone 7 series which results in no audio meaning no sound from the ear speakers, loud speakers or microphones. Occasionally this also triggers boot-loops, which is when the phone tries to turn on a fails the hardware check which causes the phone to reboot for an extended period of time.Read More
A charger port is arguably the most used part of a mobile device. This often invites dirt, lint and damage from many repeated connections.
The USB-C interface allows for a more rugged and faster throughput, but is still susceptible to failure, damage and replacement.Read More
Long screw damage can be caused on many different devices such as the iPhone 5S, iPhone SE, iPhone 6/6S and 7 series. Each model has different locations for possible long screw damage. Depending on the model of the iPhone long screw damage can range in severity from "basic" problems such as no backlight, no service or much bigger problems such as no image, or no boot caused by a 1v8 short.Read More
A flexible printed circuit (FPC) connector is used to connect to circuits together in a device or unit that flexes in a small or confined manner that does not otherwise allow a socketed connection. Often times these connectors are made from a brittle plastic that is not rated for many connects and disconnects, as such they can fail with normal installations. This service is to repair or replace a damaged FPC connector on any device.Read More
In order to determine if the Tristar IC is functioning properly, test the voltage of the battery terminal--after you confirm that the phone is pulling amps using the ammeterRead More
Typically we see iPhone 6 Plus and iPhone 6S Plus with a half backlight due to the phone needing not one but two anode backlight circuits. With one anode backlight gone out it effectively shuts off half of the led light strip in the backlight panel.Read More
The most common use of the micro coax connector is using 2 or more anchor-points which are typically grounded in the circuit then a center pin also known as the "hot wire" is what carries the signal and is mounted to a center point and runs either to other points on the board and/or through a via to connect to another layer.Read More
One problem known to the Sony Z3V owners is that the micro usb port is often times subject to failure after being plugged in and unplugged many times over the life of the device.Read More
With the aide of schematics, board views and donor parts these repairs are often feasible and much cheaper then the alternative which would involve replacing the whole motherboard, which sometimes can compromise the data on the device, rendering the information unreadable.Read More
This is a common problem of Samsung tablets, the battery connector is prone to cracking causing the flickering screen, random shutdown/restart, quick discharge, battery capacity fluctuation.Read More
Often times the boot looping issue on the LG Nexus 5 is caused by a failing power button which needs to be removed and then replaced with a new one which involves using a hot air station as well as micro soldering techniques.Read More
The most common DIY mistake when replacing a battery is prying up on the board-side and breaking the connection of many small capacitors and inductors which are needed for the phone to boot properly. The repair invovles replacing the missing components to allow the phone to charge and boot as required.Read More
Typically for a backlight to go out on the iPhone 6S would be a result of a few things, 1 being liquid damage on the motherboard causing corrosion and shorting out the backlight circuit which contains a diode, a backlight ic (U4020) as well as few other discrete components. Another way a backlight circuit can go out is also by installing a replacement screen and bridging a few of the connectors on the LCD FPC connection thus causing a short and ruining the circuit.Read More
A blown back light on an iPhone 6 is typically caused by a screen replacement gone wrong or a sudden drop on the phone which can damage some of the components on the backlight circuit.
Lets take a look at the back light circuit and evaluate the possible issues and solutions to this problem.Read More
This type of repair is common after the many months and years of plugging and unplugging the micro usb cable to charge. The physical usage this port sees with often contribute to the degradation of the port.Read More
