Original LCD Screen for Apple Watch 7000 Series & Series 1 42mm with Digitizer Full Assembly (Black)Before Installation NotesTips 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. Ensure you wear eye protection and use caution not to cut your finger on glass splinters.Tips 2: Simulate testing Screen replacement is a very fragile product. It is strongly recommended to test before installation. Please simulate testing by partially disassembling the device, connecting the motherboard with the new LCD or screen, attaching the audio cable and powering on to complete the test. If the test is successful, proceed with full installation. If there is no display, contact support immediately. Do not force installation. Responsibility is not assumed once the screen is installed.Tips 3: Do not over-bend cable Ensure the LCD cable is not over-bent. Bending beyond 90 degrees may cause black display.Advantages 1.
