Sounds like your display inverter has gone bad. You should be able to find an inverter for this model or if the computer is still under warranty I would find an authorized repair center for this brand of computer.

Ensure first that is not a system problem, see if you still have power when screen goes off, check display settings, and eventually reinstall the system.
If it does not fix it then it may be an hardware fault.

Screen flickers and goes dark u can see the image if u shine a flashlight on it. what could be the problem ?


It sounds like your LCD Backlight has burned out. You will most likely need to replace your LCD Screen, since you can still see a faint image.

My screen went dark suddenly, when I try to restart my computer the screen is tinted red before going dark again. The screen is not completely black as there is letter visible underneath.


From what you are describing, it sounds like the inverter board is failing. This board sits under the LCD screen and is responsible for taking the DC voltage from the battery and AC adapter and converting that voltage to high voltage AC power for the backlight lamp that sits inside the lcd screen. Without that high voltage the screen goes dark. Most inverters do not fail right away, there are voltage fall offs etc. Inverters are approx. 15-20 bucks on ebay, for most laptops, they can be changed out simply by removing the bezel around the screen, unplugging the two connectors on the inverter and changing it out. In most cases except Dell, the inverter is just sitting in there and is not held in by screws.

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.

Monitor Problems


Defective CCFL backlight may has the following symptom:
  • Screen flashs on red/pink and off.
  • Picture stays on in red and slowly be come normal.
  • Picture flickering with dim display.
  • Picture flickering on and off.
All these symptoms indicate that the LCD backlight lamp (CCFL Lamp)
has reached the end of the life and all you need to do is replacing the CCFL lamp


Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Laptop monitor goes black


If you're working on the computer when that happens, it's not probably a power setting. Try to update your BIOS to the most current version at the toshiba support website (support.toshiba.com) & see what happens. Fixes the issue most of the time

I hope this helps.
