Before Installation Notes Tip 1: Test before installation. When testing, do not remove any protective film or tags. Pay attention to static electricity. Before attempting any repair, ground yourself using an ESD (electrostatic discharge) strap to prevent static damage to electronic components. Wear eye protection and handle glass carefully to avoid injury from splinters. Tip 2: Test the screen before installation. The replacement screen is fragile. We strongly recommend simulating a test by partially disassembling the device, connecting the motherboard, LCD or screen, and audio cable with the new replacement, then powering on to test functionality. If the test is successful, proceed with full installation. If the screen does not display, immediately. Do not force installation if issues occur. We are not responsible for screens that have been fully installed. Tip 3: Avoid over-bending the cable. Ensure the LCD cable is not bent beyond 90 degrees, as excessive bending may cause a black display. Product Information 1.
