Are you able to see the bios screen (e.g Toshiba logo). If not, Remove your battery try running it direct to power adaptor. If still no luck, press ESC key for about 2 minutes then while continue pressing the ESC key power on the laptop. If you still didn't see or still blank...you have to replace the bulb of your lcd screen.

The "inverter" has failed, causing the screen to be very dim.
Is it cheaper to take the monitor to a "TV Repair Shop",

Blank screen get flashes, but then its all blank


When the LCD monitor display flickers and or has a black screen then the fault is usually a faulty inverter or the CCFL lamp. When you look at the screen at a sharp angle and you see a dim image then it is a backlight problem and it is caused by a faulty inverter or a CCFL lamp.

Laptop screen blanks out


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.
