I have a toshiba satellite L445D-S5976 and I am experiencing the black screen but this is different from most of the problems I've seen on here, whenever I try to turn it on the fans start up fast then they quickly slow down, but that's not the problem, everything turns on except the screen. I've tried to use an external screen but that doesn't work either, not even a flicker of light or anything, all the appropriate lights at the bottom come on but the screen just doesn't even flicker. Can anyone please help
Hey.. Well this is one of 2 problems, More than likely the BackLight on your screen is dead. Dont worry that's a common problem and the fix basically is to replace the screen. You can order the screen online and then simply remove the old one from the housing by first removing the rubber plugs then the screws hidden under the plus. lift the lid off and unscrew and replace the screen. The reason why the monitor may not be turning on is because you need to switch the primary display. If you look carefully at the keyboard you will notice that there a key written Fn usually in blue, Thats the function key. There will be another key with a blue Monitor symbol usually f8 (may not be the same on yours). you hold Fn and press that key to enable the external Monitor.
If you were doing that then this is the reason for your problem. THE GPU (graphics processing Unit ) usually called the graphics card is Damaged. unfortunately yours is built onto the ma board which means to fix this you have to replace the entire board. But thats a very very rare issue. I'm betting that the First (above) one i mentioned about the Back Light is the reason for your problem..
Becuase the fan turn on loud and then settles down it means the main board is functioning properly ad the system is booting its just that you cant see it because of the back light and not switching the display unit.

Take out the memory and reseat each memory stick one stick at a time in each slot one at a time. Be sure to turn on the laptop after each stick reinsertion. If you don't get any video then go ahead and take out the battery completely and only have the AC Adapter hooked up and turn on the laptop, this will make sure that its not an overdrained battery causing the laptop to show no video.
If this doesn't work then go ahead and take out the hard drive and dvd drive, then try turning on the laptop. If you still don't get any video then the last thing to try is to change the output from monitor to LCD, you would do this by pressing the FN key + the function key that has a pic of a monitor or it will say crt/lcd.
If after this last step you can't get video then the motherboard is bad and would have to be replaced.

it sounds like a hardware problem. I would say your high voltage board that drives your lcd has blown probably the caps you buy new on-line and replace it. send to factory service to have fixed. get fixed on warranty if you have it.
please let me if I helped

If you've replaced the LCD Panel already, then chances are good, the failing part may be the FLR inverter. It's a thin little chip about 3 or 4 inches in length that bridges the connection between the LCD and the motherboard. It's location varies from computer to computer though, so you may have to check with manufacturer documentation. They're not too terribly expensive to replace though, much cheaper than the LCD panel, anyways.
