Laptop i power up my laptop get the green light but no screen. screen goes black Toshiba Satellite P100 - Core Duo T2050 1.6 GHz Well with my laptop, it works fine until out of the blue the screen turns off complete black, but the computer is still running fine just cannot see a thing. So i restart from the power button and it usually works fine, but sometimes it repeats with the blackout. Not sure what to do about this so any help would be nice.

Touch screen is only on the C55t-A model. See note at bottom of the page.

Unlock FN key??
What are you trying to do?

The LCD can be replaced. The part is around $50-$75 I believe. It can be tricky to replace, but if you take your time, you can save money by doing it yourself. The screen sounds cracked or broken, and black & white will not work either.

good luck

Try and take out battery. Then run the laptop on the power supply only and if it does it again then your computer might need to be serviced before the motherboard dies because the Graphics processing unit is overheating. Common problem on laptops!! Thanks Igor!

Toshiba Satellite P100 screen Inverter replacement;

1) http://www.irisvista.com/tech/laptops/Toshiba-Satellite-P105-P100/remove-lcd-screen-inverter-1.htm

(You can click on any photo to enlarge it. At the top, and bottom of the page are the page numbers. They are in white; Page1 :: Page2 :: Find another model )

2) Primer:
An LCD screen cannot produce light. It needs an additional light source.
A Backlight is the additional light source.

A Backlight (Present technology) is a CCFL, or a series of LED lights.
The Toshiba Satellite P100 series of Notebook PC's uses a CCFL.

Cold Cathode Fluorescent Lamp.
Similar to Fluorescent lighting used in homes, and businesses, but on a MUCH smaller scale.

Average size is approximately 2mm Thick, and the length is close to the height of the LCD screen. 2mm is a little larger than 1/16th of an inch.

This means the CCFL can be broken quite easily, as it is fragile. (You also DO NOT want to be cut by a Fluorescent lamp )

A screen Inverter converts the power from the laptop, for the Backlight, and LCD screen.

As previously stated in a Clarification, 90 PERCENT OF THE TIME the fault is the screen Inverter.

Here is a list of compatible processors for your notebook. Just click Processors in section Compatible products and you'll see which core 2 duo processors are supported.

oooo man that ones a doozy, if its the one with the go9700 video card its a pretty bad model. the card brand new is 700+ from toshiba. i have run into that problem quite a bit.

My laptop is Toshiba M300 and I use FM Tuner Utility under NXP FM Tuner in all programs.

Well you can look if you pluged cable into GeForce not into motherplate second you can try it on another laptop if it works well you must repair your computer

did you go to toshiba and see if they were listed on their website?
If so let windows put in their own drivers.
uninstall them from device manager and scan for hardware changes.
