Question about Toshiba Computers & Internet
This is usually to to the graphics chip not being properly soldered to the circuit board - the chip is probably what is known as a ball-grid array and these are notorious for this problem.
If this is the case then you really cannot fix it and it will need a new mainboard.
If it is a loose connection to the screen then you may have a dodgy graphics cable which leads from the mainboard to the TFT display panel. Sometimes it may be that the connector on the mainboard is loose. If this is the case then it may be worth trying to take it apart (if out of warranty) and check that the multi-wire plug leading to the screen is firmly seated into the connector.
However, taking apart a notebook is quite tricky!
