I keep getting a full white screen on my laptop, how do i get rid of it

See if it is the laptop monitor by hooking up an external monitor. If that monitor works, your laptop screen has a connection bad that might be caused by the ribbon cable (if the cable carries the common), but given the symptoms, it can almost be assumed that some type of power problem exist with the lcd layer. The screen would be all white if the common circuit is open. The screen is white because the backlight is showing - because there are no darkened lcd pixels.
In all probability the monitor itself is not bad, it just has no lcd layer power. Another problem could be in the the video board where the output to the back gives power but does not power the resident laptop screen. Most likely it is a connection though.
If you are inclined (and it is out of warranty!), carefully disassemble it and start gently pressing connectors or wiggling (careful!) the cables. Chances are, the screen will try to work. Find the bad connection this way and burnish the contacts if needed, add contact grease (smathering only) and reseat the cables.
