Hi everyone, Welcome back to geardo,
Today we will show you how to replace the LCD Assembly on the Samsung Galaxy S20 mobile phone.
To start, we need to have the right tools to proceed with the repair,
which You can find in the description.
This replacement guide is based on the lcd assembly with frame installed.
First, Take out the Sim tray and then the back cover removal.
To remove the back cover, it needs to heat gently
around the back cover edges until the pasted adhesive becomes soft.
For this, we are using a heating pad. Place the back cover side on the heating
pad and Select the mobile phone HEATING option and leave it till
it completes. Alternatively, you can use a heat gun or hairdryer.
Once the heating has completed,
Use a suction cup to create an opening between the frame and rear cover.
Next, insert a plastic card pry tool or something similar to cut the adhesive around the back cover.
Next,
take out the back cover. And, undo five screws and disconnect the connector
to take out the wireless pad. ANd also disconnect the battery plug.
Next, take out the logic board frame by undoing five screws.
Next, disconnect and take out the front camera.
Next, take out the logic board by disconnecting six connector plugs from the board.
Be gentle and lift the panel using a pry tool or tweezer.
Next, Apple little heat and take out the earpiece unit and the flex from the body.
Next, move to the bottom and undo five screws to take out
the secondary board cover with the speaker.
Next, disconnect and take out both main ribbon flex cables.
Next, undo three screws and take out the charging port board from the body.
Next, apply little heat and pull out the vibrator motor from the body.
Next, take out the battery from the body.
First, apply little to soften the glue on the battery. For this, we are using a heat gun.
Once you feel the heating is enough, use a card pry tool to cut the adhesive under the battery.
And Once you have some space, use a pry tool to lift the battery.
Now the only remaining part is the broken front screen assembly with the frame and buttons.
For the replacement, there are few different screen types in the market.
The most common is the Original service pack screen, which comes with the frame and buttons.
There is another type, it is original but without the frame. But the repair job
is a little bit difficult and time-consuming, and the price difference is not that big. And
also, there are refurbished & used screens with the frame and without.
I would recommend you to go with a screen with the frame & buttons installed.
It can be original, refurbished, or used. And this type is commonly available to purchase.
Next, on the new screen frame, start placing removed parts.
First, place the sensor flex and the earpiece on the body and then place the logic board.
And then secure the sim tray and front camera into the board.
Next, place the battery in the body. If needed, add adhesive to the battery.
Next, secure four connector plugs in the logic board and place the frame by securing five screws.
Next, move to the bottom and first place the vibrator motor on the frame.
Next, place the charging port board and secure it with three screws.
Next, place both main flex cables and connect them from both ends.
Next, place the secondary board cover by adding five screws.
Next, Before placing the wireless pad, it is good to connect the battery plug and
test the screen functionality by powering up the device. Once the testing has passed
Next, place the wireless pad by securing the connector.
Next, Before installing the main back cover, make sure it has enough glue on it.
If not, use B7000 glue or a new double-sided back cover adhesive.
Finally, we are using screen binding clips to tighten the back cover to the body.
If not, you can use rubber bands and leave them for some time.
I
hope you have enjoyed the replacement guide.
