If you have another account on your laptop that has administrator rights, log in into that account and change the password for your account. If you have an administrator account (even if you don't try putting in Administrator and leave password field blank) try using that account to reset the password, otherwise try one of the following:
are you trying to put win 10 on as it can do this some time, can take upto 10 15 min to load, when the like is flashing its dos, when the screen is black its windows it takes some time for windows to find a driver and load it so the screen comes up. i've had this on a200's before. if you keep rebooting you will need to wipe the hard drive and start again. this also does this on win 7 and 8. win xp it does not do this as its full dos setup .
Take a flashlight and shine it on the screen. If you can see an image, you probably need to replace the power inverter board. It supplies power to the backlight.
It's a motherboard hardware issue in all likelihood.
There is NOTHING you can do but update the firmware bios. The problem is that most bios firmware update programs require both ac and battery power at the same time :(
You can try to do it anyways by visiting Toshiba's support page for your model and downloading the firmware from there.
It probably won't fix the problem but it's still worth a shot....sometimes it works ;)
