I have a much loved Toshiba laptop, its about 3 years old
Recently the screen would suddenly go blank at random times. When that happened I could se something by looking at the screen from a sharp angle, but
not enough to be able to control the computer. Cure is to switch the computer off and let it restart, The fault will then re-occur maybe 30minutes or
5 seconds later, it's got worse recently and I've had to retire it. It's a shame, though, because I've got some good stuff on
it.
Things is, when I plug in an external monitor that goes blank as well, when this happens, so I don't think it can be the backlight alone (though
I don't really know about this stuff)
Any help or ideas much appreciated
It's not the backlight - that'd only affect the built in screen. If it only affected the built in screen I'd blame the ribbon cable
that joins the lid to the body - it often fails with age. but...The monitor output as well....
I'd have to blame the internal video card failing. It's not a servicable part really - unless you have serious soldering skills and parts to
hand.
If it's happening after a time it can often be heat. A damn good clean with a can of air may blow out the dust and dirt?
You will find dozens of different cures for this on the web the two easy things you could try are using a vacumm to clean the ventilation slot and
taking the memory out and re-seating it.
If that doesn't work my money is on a motherboard fault although it could be a defective memory module.
or if its like some gpus it mite be suffering heat so you could take the heat sink off and put some new paste on it and try again just a thort it sorts xbox360 some times
Easiest things first, have you got the latest video drivers installed?
I've had the exact same problem with a Dell Laptop of about the same vintage and the latest drivers solved it.

my mums IBM laptop did the same thing after about 6 years. never tried it plugged into an external monitor though.
friend had a old screen for this paticular laptop which fixed it when swapped. only thing is it now doesn't have bluetooth, but it never actually
worked anyway lol
