2 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.
Asking because I'm cheap -retired, fixed income.

Any identification on your logic board? Any number will help

Can you check to see if your board is a P7YE0/P7YH0/P7YS0? I do have that schematic and it should be for a 7750

WoW, change your name to SpeedyBird! Mine has P7YEO U98 on a sticker where the memory would fit. Above that # is 3LMFG: 138 I presume its a date code

Contact me by email so I can send you the schematic. It does not have a board layout, so you'll be looking for the reference designators on your logic board. My email address is in my profile, just click my avatar

Researched you a bit and am in awe. Hope I can return the favor someday.
