Hi,
I've fitted a new LCD to my Toshiba Satalite Pro C850-1K4 laptop, but made the school boy error of not removing the battery.
The new LCD is blank when the laptop is powered up.
After refitting the old LCD, this is also now blank.
The motherboard to LCD cable looks okay, no broken connection.
There is output from the HDMI socket to an external screen, and if I look closely at the LCD under a bright light then I see a faint image, so my conclusion is that there is a fuse or similar component on the motherboard that is preventing power to the LCD backlight.
I've attached an image of the LCD connector on the motherboard. Can anybody help me identify the faulty component, or offer any advice on how to fix the blank screen?
Thanks
Dean
