Today, we've got a Samsung Galaxy A6 with us in the workshop that's facing charging issues. We're jumping straight into the matter and inspecting the charging connector under a microscope. On the exterior, it's evident that the charging pin is entirely broken, so our next step is disassembling the phone.

Using a heat gun set at 90°C for about four minutes, we manage to lift the screen. Since this model opens from the screen, caution is key when lifting it. We've used this technique numerous times and have managed to lift hundreds of screens. If you're attempting this at home without these tools, a hairdryer could also do the trick.

The device was shipped to us from an online customer, and the repair cost, including shipping, is set at 69€. As a technician, mastering various techniques and offering quality diagnostics is vital to save on repair time.

If the phone cools down, reheat it for 3-4 minutes to keep the adhesive warm, and progressively cut through it using a plastic card. Once we've lifted the screen, we disconnect the plastic connector and raise the screen connector.

Following this, we remove all the screws from the intermediate housing using a 1.8-star screwdriver. A crucial step here is also to remove the SIM tray.

Using a plastic pick, we now separate the intermediate housing from the back cover.

Up next, we connect a lab power supply directly to the battery connector using Power Z. This helps us understand if the device is functioning correctly.

We use a metal clamp to press directly on the power button pins to switch on the phone. Once it powers on, we verify if the motherboard is showing regular consumption using the Power Z software.

In order to be completely sure that the device has normal consumption, we put it into power-saving mode. Ideal consumption should drop to zero.

Once we have the diagnosis, we communicate with the customer and provide the repair cost.

Now we move on to the main repair, removing the broken charging connector. Using a JBC brand hot air station set at 400°C and 60% air, we remove the connector.

We then clean the old solder using flux and solder paste, and then a desoldering braid. After cleaning, we use isopropyl alcohol or contact cleaner to remove the burned flux.

We then apply solder paste, and place the new charging connector. To solder it, we reduce the temperature to 300°C and 40% air.

After successfully soldering, we get a sturdy and shiny finish. For added strength, we also solder the sides using the soldering iron at 350°C and a leaded solder wire.

We then reassemble the device and check the results of the repair.

The device seems to have run out of battery, so we need to wait for it to charge a bit.

We see a charge of 500 milliamps, indicating that the device is slowly charging the battery.

Finally, the phone is charging correctly at 1.1 amps.

In this video, we've managed to diagnose and fix the charging issue in a Samsung Galaxy A6 by replacing the charging pin. I'm Leonardo, and I'll see you in the next one!
