Replacing the display on the example of Meizu M6

Often phones come in for repair, for which this is not the first "visit" to a service center. Our Meizu M6 – just the same of these "experienced".

Typical cracks for analog displays (thin glass, high formation of glass chips), dark blue proximity / light sensor window and dried glue. We take a new module and proceed with the repair.

With an eye on Apple, Meizu from the first models equipped its phones with the same bottom pair of pentalobe star screws. We twist both. Even on the remnants of plastic, but they still hold the back cover, we will not allow further damage.

Now remove the SIM card tray. If there are no paper clips or needles at hand, you can pry off with a thin and flat tool.

The case is small, with a spatula for parsing, disconnect the back cover and remove it.

Under the cover, we are waiting for the main board with the necessary connectors. Everything is securely covered with a plastic cover on seven screws.

After gaining access to the board, immediately turn off the battery.

Due to the specific touchscreen loop, we will need to dismantle the board, disconnecting all marked components from it. After that, the board is easily removable.

That is the reason why we had to dismantle the board. A touchscreen cable with conductive pads that connect to the board through flexible contacts. The same reason will not allow us to check the new display module without deleting the old one. So that’s what we’ll do.

We send the phone to warm up on a thermal mat. 99 degrees and 3 minutes is enough for a factory sizing display. In our case, the display almost fell out after 30 seconds.

During the time that passed after the first (or not the first?) Replacement of the display, a fair amount of dust and dirt poured under it, because of which it did not hold well.

In the lower part, the glue dried out almost in the form in which it was applied. This often happens when the display is not pressed firmly to the frame.

We assemble the phone for verification, insert a new display, return the board and all connections to place, and screw the plastic pad into place. The pad will need to be fixed with two screws, then the flexible contacts will provide a reliable connection to the touchscreen.

After starting the device, we check the functionality of the display module. Image quality, whether the backlight is uniform and whether there are any distortions or graphic artifacts. We check the touch screen using the “improvised” means: dragging and dropping icons, pulling curtains and scrolling through lists.

Spare part passes the test, which means we will install. Everything is already simple here: we clean the frame of old glue and dirt, degrease it with alcohol and apply B-7000 glue. We give it a little dry (5-10 minutes) and glue the display.

We recommend that you press the display to the case using special clothespins. If there are none, you can send the phone under oppression or use stationery rubber bands.
