Hi, I am new to this forum. I have problems with my laptop (Toshiba) not having the screen turn on when i start it. The other lights turn on just not the screen!!!!. I have tried turning it off/on by pressing the power button. There is no battery that i can get access to pull out & put in. Any help would be greatly appreciated.

What is the make and model of this computer?

 

If this is a laptop it should have a VGA output.  Have you tried using an external monitor to see if the problem is with the laptop display?

Thanks DC3 for your suggestion. I have tried hooking up my Toshiba Satellite (model # S50D-A) laptop PC to my home desktop PC monitor & my laptop was able to display itself on my home desktop monitor. Unfortunately, this doesn't fix my laptop monitor display problem but does hopefully narrow down where the problem lies. What do I do next??????

Now we know that the video output is working which points to the problem being with the display.  Try this, take a powerful flashlight  and shine it on the display after starting the laptop.  If the backlight has gone out you should be able to see the desktop when the light is shined on it.  If the desktop is visible you need to replace the backlight.  If you can't see the desktop the inverter may be bad.  There is also the possibility that the ribbon cable is loose or has a wear spot from opening and closing the lid.
