For iPhone 13 HD Incell LCD Screen Before Installation Notes Tips 1: Test before installation. When testing, do not remove any protective film or tags. Please pay attention to the problem of static electricity. Before attempting any repair, be sure to ground yourself with an ESD (electrostatic discharge) strap. This will prevent static electricity from damaging the electronic components within the phone. Ensure you wear eye protection and use caution not to cut your fingers on glass splinters. Tips 2: Simulated testing. Screen replacement is a very fragile product. We strongly suggest testing before installation. Please perform simulated testing, which means taking the phone apart (motherboard + LCD or screen), connecting the audio cable and new replacement, powering on, and testing. If the test is successful, please proceed with installation. If the screen does not display, please contact us immediately. Do not force the screen to be installed in the phone. We will not be responsible once the screen is installed. Tips 3: Do not over-bend the cable. Please make sure the LCD cable is not over-bent. Bending over 90 degrees may cause a black display.
