It could be a couple of things:
1) The backlight could be dead:

ANYONE KNOW WHY MY TOSHIBA SATELLITE L645 BECOME BLACK SCREEN BUT THE PROGRAM STILL RUNNING ?


you probably don't need a new screen it's probably your screen inverter that's going. It's just a small strip at the bottom of the screen wjth a little circuit board. If you google screen inverter and the make and model of your laptop you'll see what I mean.

How to solve Toshiba satellite L645 From black screen ?


You may have a faulty inverter, it supplies high voltage to the CCFL lamp.
If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp. Please click on this link and follow my instructions to identify the fault and possible fix :- http://www.fixya.com/support/r3598095-faulty_laptop_lcd_screen

Please help, My laptop Toshiba Satellite L645 blank screen when turned on, there is absolutely no view. please help me ..................


Can you tell if the laptop itself is turning on?

If not then there is an issue with the laptop.

If the laptop is turning on then try plugging in the laptop to an external monitor and see if you get anything on the screen. If the laptop works normally with the external monitor then you will need the screen replaced . If the laptop still shows nothing on the external monitor then you will need to repair your laptop.

Please rate if this helps

I have Toshiba 14" Satellite L645 i5450 notebook


It is possible to connect a modem to the laptop. Connect the modem to the laptop using the telephone style socket on the laptop. The mother board will then pick this up and load the relevant drivers for your modem.
If you are not sure, contact Toshiba online. They are extremely helpfull.
Hope this helps.
