Antwoord op "Replaced Screen But Blank Display"This issue is caused by a fault motherboard. After much research the main issue on my Z3 d6653 is that the battery provides less than adequate power to the graphics processor. In order to display the pixels. There is 2 solutions. Replace the motherboard or battery by using a multilayer and testing the fuse to the power to the graphics card. 2. Install a custom rom and downgrade the graphics software so that it doesn't require as much intensive graphics processor. It the same issue you encounter on a pc that has a weak power unit and a beefy graphics card. Hope this helps.
