Tips for Safe Installation: Tip 1: Test Before Installation Ensure the screen is functioning properly before installation. Do not remove any protective film or tags while testing. To prevent damage from static electricity, ground yourself using an ESD (electrostatic discharge) strap. Always wear eye protection and handle the glass with care to avoid cuts from splinters. Tip 2: Simulated Testing Since screen replacements are fragile, we recommend simulating a test before full installation. Connect the motherboard and the new LCD with the appropriate audio cable, then power on the device. If the screen displays correctly, proceed with the installation. If there are issues (e.g., no display), contact us immediately and do not attempt to install the screen. Tip 3: Avoid Over-Bending the Cable Be cautious with the LCD cable; avoid bending it more than 90 degrees, as excessive bending can result in a black display.
