The display dim after the screen is lifted to a certain point

Hope someone can point me in the right direction (LCD Screen, Crimped Cable, Backlight, Battery?????)

I have a Toshiba L505D-S5992 Satellite laptop. Recently the display began to dim after the laptop screen is lifted to a certain point (i.e. 1/2 way). The symptoms after hitting that 1/2 mark (same every time) are consistent with an Inverter/Backlight failure. I replaced the Inverter and still have the same problem. The LCD is normal (no spots, lines etc… until the LCD screen is lifted to 1/2 way then the screen Darkens to black although you can still feintly see the image if you shine a light or look closely enough. Attaching an external monitor works fine.

I think this is problem with the video cable. Most likely the backlight fails because the vide cable not making good connection with the motherboard or the video cable is defective.

Here are a few things to try.

1.Remove laptop keyboard and reseat the video cable connector on the motherboard. Make sure it’s plugged correctly, all the way in. Test laptop after that.
2. Access the back side of the LCD screen and reseat the video cable connector on the back. Test laptop after that.
3. Replace the video cable with a new one.

  1. My laptop’s sound system used to be working normally but it stopped after I plugged an external computer speaker to it. It won’t play through my headphones either. I wonder whether it’s a hardware issue?

  2. … to clarify, I have a Toshiba Satellite Pro A200

  3. I have the same problem and have narrowed it down to the cable which runs from the motherboard to the inverter. When I move that cable ever so slightly I can get my display back. One of those small wires must have broken with repeated screen opening/closing. The inverter end has 6 pins but I don’t know how what the motherboard end looks like. Anyone know? I would like to order the cable and then tear the computer apart to fix this.

    I’ve run into this same problem multiple times with your same Toshiba model. It was the cable in almost every case.

    This same thing has happened to my Fujitsu Siemens laptop. I don’t know what to do. Please recommend the cheapest solution to me. Thanks, sir.
