Ive got a toshiba satellite pro a200 laptop that has been giving me some problems.
On start up the toshiba splash screen displays perfectly fine the the screen goes black.
On closer inspection the screen is not totally dark as I have tried shining a flashlight on the screen and I can see the windows login page so the machine seems to be starting up fine.
Also if I put the machine in sleep mode and wake it up the windows screen displays perfectly fine for about a second then all goes dark again.
From what I've read so far it sounds like it could be a screen inverter or backlight problem.
Is there anyway to diagnose between the two possible causes.
