My Taushiba laptop screen has gone red, every document or webpage shows in either turquise blue color or red.

This is a sign that the backlight that lights up the screen is going out. You'll need to buy new backlight and install it yourself (which requires taking the laptop apart) or pay someone qualified to do it for you. -Ryan Adams
