Pre-Installation Notes
Tips 1: test before installation
Do not remove any protective film or labels when testing. 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 of the phone.
Be sure to wear eye protection and be careful not to cut your finger on glass splinters.
Tips 2: Simulate tests
Screen replacement is a very fragile product. We strongly recommend testing prior to installation. Simulate test which means mobile phone separated (motherboard + LCD or screen) connected audio cable and new replacement power on test finished. If the test is correct install it. If it is not displayed, please contact us at the first time. And please don't force install it on mobile phone. We will not be responsible once the screen is installed.
Tips 3: Do not over-bend the cable
Make sure the LCD cable is not bent too much. More than 90 degrees bent will cause a black screen.
