I have a Backlight Failure in my Toshiba Satellite X205-S9800. In the past few weeks when I turned on the laptop the screen was red and then would slowly turn to normal colors. Same when the screen was waking up from sleep. And today it turned off while I was working. I can barely see the icons on the desktop. I found an article on this site which says that there could be three different causes of this failure - Lid Close Switch, Faulty Inverter Board, or Backlight Lamp. So how do identify which is the cause in my case?
Hi @fhertzwo To do this you would need the schematics for the motherboard so you could determine exactly what the cause of the problem was, otherwise it is only guess work, which could possibly take a long time. You would also need to know how to read schematic diagrams and how to use a digital multimeter. What is the model number of the motherboard, (printed on the motherboard)? Knowing this may help to find a free download of the schematics, as the only thing that I could find in the way of schematics by using the laptop’s make and model number was this supplier but you have to purchase it.
