Hi, Thank you for posting your query on fixya. The screen could exhibit such issue , if the screen has gone bad or the video card that give signals to the screen. To isolate the problem connect the laptop to an external monitor / TV if the output on the same is fine , the video card is fine and the screen would need a replacement.
Hook a spare monitor to the video output of the laptop, if picture okay! the LCD panel display is defective and most be replaced. But if symptom is the same on both screens it indicates a bad Video Graphic Card normally built into the motherboard.
The ribbon cable to the lcd layer (green pixel contact common) is going bad or the connection of the cable to the lcd unit is dirty. It is probably the connection, as the ribbon cable, if installed correctly, will flex many more times than the hinges would be able to (that is, the ribbon cable should outlast the laptop). Sometimes they might not be installed correctly in that there is a hangup or kink of some kind and the bending (each time the laptop is opened and closed) makes it bend beyond the elastic limit of the metal, and it eventually cracks. The problem you have may be cause by the cracked metal in the ribbon cable, and careful placement of the screen makes the cracked trace reconnect by flexing. It could be caused by a bad contact of the cable to the board or (most likely) the screen unit.
If you are inclined, take apart and carefully inspect the ribbon cable for any parts that have a kink in it or is otherwise flexed too much in one small little area. Flex the cable to see if it changes the display. Otherwise, wiggle the ends (careful) to see if it will try to work.
If you find a cracked cable, have it replaced. If the contacts prove to be dirty, unplug or otherwise remove cable end that is dirty and reseat cable after carefully burnishing contacts and using contact grease (smathering only).
It could just be the drivers for the video card need to be reinstalled.
Pop over to the Toshiba website and you will find them in the download area.
Before you go there though, right click on the desktop and bring up the display properties. The card may have reverted back to a low colour bit setting. If so, set it back to 32bit and that should make it a happy camper again.
Right-click an empty area of the Windows Desktop (your main screen). Click Properties, then the Settings tab. Under the slider labeled Screen area or Desktop size, slide the slider and click apply until you find the size that takes the fuzziness out of your laptop display.
