I have a Toshiba Satellite A75-SS291(one year off warrnety of course). About a year ago I started having problems with the screen. The slightest movement or sometimes for no reason at all and the screen would go white with vertical lines. Finally one day it just went dim. It to took it to be repaired and they seemed to have fixed the problem. About 3 months later it started with the lines again or going black if it moved it. I figured it was a short or something with the video to the screen. It worked fine if I plugged in an external monitor. Than other issues started.

When I powered it on it would powerup, I could hear the fans, but the screen remained blank, even with an external monitor. I would have to power it on and off several times before it would run through it's cycle and boot.

Than came a windows update that messed up my system so that it would not boot into windows, but would just keep rebooting. One day it would not start at all. The power would come on, I'd hear the fans start but the screen stayed black and the fans stopped. I thought it was the hard drive, because of the windows problem, so I switched out the hard drive, but it still will not do more than run the fans for a few seconds than stop. The power and battery lights stay on. I've tried it without the battery, just running on AC and the same thing happens. I switched out the memory, but still nothing.
The laptop is less than 2 years old. I've worked on desktops for years, but have not done much work with laptops, so I'm not exactly sure what to check next.
 
Definitely not the hard-drive. If it were, you'd at least get the POST screen before it wigs out on you.

Serious hardware error then. Obvious possibility: Motherboard. If your power isn't getting where it needs to be due to the mobo's power management circuits screwing up then you won't get anything useful on-screen. Could be the CPU but with the monitor issues you've been having I would honestly believe it to be your motherboard.

Which means a new laptop. Sorry.
 
i had that same issue recently but i was lucky it happend when i got the laptop.
it is the laptop itself best bet is just to get a new one. there is nothing you can do to fix it.
