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!

Tips for a great answer:
Purchase an ink refill kit that is specific for the HP 27 color ink cartridge. Look over the packaging to insure that it states that the kit is for the particular make and model. Using other types of cartridges may not work properly.
Place several paper towels down to prevent any ink residue from damaging other objects. Place the ink cartridge onto the paper towels. Put on a pair of rubber gloves to prevent ink from staining hands.
Peel off the top label gently from the cartridge.
Observe the three holes that are located on top of the cartridge. There is a solo hole located near a rectangular tab that protrudes and two other holes located next two rectangular indentations into the plastic on the top of the cartridge.
Take a toothpick and gently stick it down inside each hole to verify the color. Take a sharpie marker and mark next to each hole with the correct coloring for ease. Use "M" for the magenta color, "Y" for yellow and "B" for blue.
Take a piece of masking tape and place over two of the holes to prevent ink spillage from mixing into other color positions.
Read over the ink cartridge refill kit for the appropriate amount of ink needed to fill the syringe with the correct color for the uncovered hole.
Expel any excessive ink from the syringe. Insure that you have the correct amount of ink by following the markers on the side of the syringe.
Place a paper towel over the end of the syringe and while holding the tip upwards, gently press or tap the syringe plunger to expel any air.
Insert the syringe needle into the appropriate color hole until the tip hits the bottom of the cartridge. Pull the syringe up a little from the bottom of the cartridge to prevent blockage when expelling ink.
Expel the ink into the color hole slowly. Stop if ink begins to protrude out of the color hole. Take a cotton swab and gently wipe the outside of the color hole and then cover with tape.
Take the syringe apart and rinse thoroughly to prevent ink colors from blending. Take a cotton swab and dry out the inside of the syringe.
Repeat above steps for the remaining two color positions that are left.
Gently take a needle and put a hole in each tape that covers the color holes for ventilation. Allow the cartridge to sit for at least one hour after completing refill instructions.
Reattach the original top label.
