Cog LCD Screen with Digitizer Full Assembly Before Installation Notes Tip 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 to avoid cuts from glass splinters. Tip 2: Simulated testing Screen replacement is a very fragile product. We strongly suggest testing before installation. Please perform a simulated test, which means opening the mobile phone, connecting the motherboard, LCD or screen, audio cable, and the new replacement, then powering on to complete the test. If the test is successful, proceed with installation. If there is no display, immediately. Do not force installation. We will not be responsible for any issues once the screen is installed. Tip 3: Do not over-bend the cable Please ensure the LCD cable is not over-bent. Bending beyond 90 degrees may cause a black display. About the product 1.
