For Samsung Galaxy Tab A7 10.4 2020 SM-T500/T505 Front Screen Outer Glass Lens 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 device. Ensure you wear eye protection and use caution not to cut your finger with glass splinters. Tips 2: Simulate testing Screen replacement is a very fragile product. We strongly suggest testing before installation. Please simulate testing by disassembling the tablet, connecting the motherboard, LCD or screen, and audio cable with the new replacement, then power on to test. If the test is successful, proceed with installation. If there is no display, contact the seller immediately. Do not force installation. The seller will not be responsible once the screen is installed. Tips 3: Do not over-bend cable Please ensure the LCD cable is not over-bent. Bending beyond 90 degrees may cause a black display.
