How do I test a display before I install it?
When buying a new display, it is important to test it before it is definitely installed. Unfortunately, it can happen that a display is damaged in shipping or has a defect from the factory. Testing can save you the time of having to remove it again if something is wrong. In addition, you can only use the guarantee of https://phonedepot.ch/gb/ on the display as long as it has not been definitely installed, as this is the only way we know that the damage has not been caused by improper installation.
The initial situation
But how do you test a display without installing it? First, it is important to prepare everything. To do this, the smartphone must be opened and dismantled as far as is necessary to replace the display. Depending on the device, this can mean only opening the device or removing several parts. Now the display can be tested before installation.
The test
To test the functionality of the display, the connector / LCD flex cable must be connected. If the battery has been removed, it must also be connected. On units where the power button is now usable, this can now be used to switch on the display and test the functionality. If no power button is fitted, the contact of the button must be cleaned with a spatula Spatula or a Tweezers to switch on the unit.
Continue with the installation
If the display works as desired, you can now proceed with the installation. To do this, first carefully remove the connections made for testing. Then the installation can be carried out normally.
Important: The warranty stickers on the display should only be removed after you have made sure that everything works. Once they have been removed, there is no longer any claim under the warranty.
