I have a Toshiba Satellite A105-S1712 laptop. One day I shut it down (full shutdown, not forced or hibernation) and left for a few hours. Computer worked fine up till then. Came home, turned it on, and there was nothing on the screen. Powered on, gave startup sounds, acted as if it was ready to go, but still, nothing on the screen, not even getting brighter.
Hooked up external monitor and that worked fine (has ever since, unfortunately). Tried using Fn + F5 to switch the screen view, and that wouldn't bring back up the lappy monitor. Took it to a comp guy I know, and he figured it was the inverter (after testing to see if there was power flowing through the inverter, and there was none). So we finally got a new one and just put it in. Still nothing on the lappy monitor, still works externally, even trying Fn + F5 to switch back.
Computer is now almost two years old, with normal everyday use. Of course, back when we originally tried to contact Toshiba about it, it was two weeks out of warranty.
I believe the comp guy took the RAM out and put it back in (in the whole process, not specifically) so it should be seated properly. The connections and such to the LCD are all ok, no loose or cut wiring. I'd hate for it to be the motherboard.
Help, I'm tired of being tethered to the desk, I want to be mobile again.
Also, it'd be great if someone could link me to a repair manual or configuration manual online. Toshiba's website doesn't (or I'm not finding it) have a repair manual. I know someone who might be able to find the problem and fix it if he could see where to look.
