This isn't a problem with the touchpad, it's problem with your display control board. The display board would need to be replaced to fix this issue. You will need the model number to look up the correct display board. If you can't find one, then you'd need to send your old display board to a place like Core Centric Solutions to have the display board refurbished. That usually takes 2 weeks and costs $200 or so.
