Samsung Galaxy S8 Screen Replacement – An iFixed Guide
Before starting the repair, it is essential that pre-checks are completed. These specifications are required on all devices to measure the level of damage that is displayed on the phone.
Our technicians will examine the damage that has been caused to the device. This level of damage will be noted checking for bends or dents that may stop the screen or other parts sitting perfectly on the assembly.
After heating the device for a considerable amount of time, the iSesamo tool is wedged between the mid-frame and the back cover, splitting the waterproofing adhesive which secures the back cover.
The iSesamo tool is substituted for a plastic razor once the adhesive has started to split. The new tool is worked around the back cover, separating it from the mid-frame. The fingerprint scanner should then be detached from the now separate parts.
There are 14 Phillip screws holding the upper and lower antenna assemblies in place. Once removed, the assemblies will no longer be secure to the mid-frame.
The spludger will pry and detach the upper antenna and wireless charging assembly. The lower antenna assembly should now be free to remove.
Before proceeding with the repair, the battery must be disconnected. Trying to complete the repair with a live battery can cause numerous complications. The most common being an surge of power making its way to the screen and destroying the LCD.
The front facing camera is disconnected from the upper section of the mid frame. A plastic spludger must be used whenever disconnecting a component from the motherboard. By using an alternative tool there is a high risk of ripping the socket from the board, leading to much more timely and expensive repair.
The same must be done for the sensor array cable. Once disconnected, it is safe to detach the LCD/ digitizer connector. This cable is solely in charge of the touchscreen and display, so be extra care is needed.
The antenna cables which connects between both the motherboard and daughterboard/charging port must now be disconnected. These are prone to snagging if pulled or moved with force, an issue that could occur with an cable or ribbon within this device.
There is another ribbon located between both the motherboard and daughterboard/charging port. Use the spludger to disconnect, allowing the top motherboard board to lift away from the assembly.
The front facing cameras should now remove from the device with ease. It’s always best to use your tweezers for this part of the process. It is one finicky job! The vibrating motor should also move from the framework with ease.
The headphone jack must be unscrewed and detached from the motherboard. There are five screws that secure the daughter board/charging port to the bottom of the frame. Once these are removed the charging port should freely detach from the frame.
The sensory array should now be removed with ease. Tweezers should always be used for this procedure.
Unlike previous models, the battery does not have any tabs to help remove the adhesive from underneath the battery, The round side of the iSesamo tool is pried under the cell, breaking the adhesive while lifting it from the mid-frame.
After applying the specialist adhesive tape, the battery can now be placed into the new screen and mid-frame. Always use adhesive tape. In the past, customers have glued there battery back into the device. This may keep it extremely secure, but all batteries need room for expansion, otherwise they are prone explosions.
The sensory array is transferred to the new assembly, ahead of the motherboard being refitted.
The lower daugtherboard/charging port is then placed and screwed into position. The headphone jack is then connected and screwed into place. The five screws must be reused to secure these vital components.
Both the front camera and vibrating motor is transplanted into the new mid-frame. The front facing camera slides under the lip of the frame.
After the motherboard has been fitted and connected to the daughterboard/charging port, both the antennas and LCD/digitizer ribbon can be reconnected to the central motherboard.
Both the sensor cable and battery can be reconnected to the motherboard. Be careful when plugging the ribbons back into the sockets, if pressed in the centre when reconnecting there is a major chance of bending and breaking the component.
Once all of the ribbons and cables are reconnected to the motherboard, the lower antenna assembly can be screwed back into place. The assembly also doubles up as a cover for the daugtherboard and charging port.
Before the repair can continue, a screen test must be performed. The test includes dragging an app around the screen and checking all letters on a keypad to identify any dead pixels or blemishes in the screen.
Now the tests have been completed, the upper antenna/wireless charging will be secured back into place using the 14 screws used in the previous assembly.
Special adhesive is then worked around the back frame and gently placed onto the back of the mid-frame. After the glue has set, the repair is complete.
