LED-Backlight Dark for Acer Aspire 7750-6423 LCD Screen
The LED backlight on the LCD laptop screen is dark. I have researched dark screen enough that I am now sure the screen itself is functioning. I cannot find (and ACER is no help) any connection info (schematic,connector pinout,fuse location, or part layout) on how the motherboard feeds the backlight voltage to the screen.
YouTube and manualslib.com were most helpful but not component detailed enough. All 7750 models similar in many respects.
