I dropped my laptop it powers up but the screen stays black. How do I reset the monitor?

either your backlight has failed or you have hit one of the function keys which selects external monitor- can you connect it to an external monitor to see what happens?

hi

try to isolate using external monitor,
check connection of lcd cable
replaced lcd panel

unplug monitor cable with power on, see if any message will come up on screen, if message appears , cable replacement needed

Your monitor have board problem.Need for repair and troubleshoot.Maybe a deffective power supply.

hi you will need to reinstall the vga of the system to enable it not to write that again

motherboard and graphics adapter may need replacement

This could be one of two problems, the light in your monitor has a loose cable, or the light is dying. I have seen cold cathode lights that are about 10-15$ to buy and many instructions on putting them in yourself.

Solution 2, your cable is loose on the back of the monitor. Make sure you have the screws tightened on either side of the vga or dvi cable, both on the back of your monitor and on the back of your computer or laptop.

Hi, I don't think the problem is with your monitor. Your monitor sounds like it's doing exactly what it's supposed to do. The monitor is supposed to turn off if there's no cable attached, which means there's no signal input. When the screen goes black, does the power light stay on and turn orange? or does it go off as well? I would recommend that you lower your screen resolution to 1280x1024 or lower in the Display Properties window, then remove your primary monitor, and connect the monitor to your desktop computer. You should see it light up when connected. The monitor auto-senses when there's a computer attached to the cable and when there's a signal. If it doesn't see a signal, it goes black to save power.

have you tried either switching between external and internal monitor usally Fn + F5 on toshiba or try plugging a monitor into the back and see if it displays.
if you get a display on the external monitor then its probably a screen or inverter fault if you donot get a display to an external screen then it is likley t be the graphics on the board itself.
hope this helps

Repaired! This sounde like a fuelty screen or screen inverter. To check this, connect to an external monitor, if the external works properly, then it's the screen or inverter. If the external doesn't work, let me know and we'll run the problem down to a more indepth (internal) trouble shoot.
