Title:

Pink lines suddenly appearing on display

Text:

My macbook's main display has mostly horizontal pink lines that flash within certain fields on the screen that are otherwise normally white (browser windows, text fields, etc.)
 
It happened spontaneously and without warning a week ago. The display was fine one minute, then suddenly the pink appeared.
 
My external display that runs out from the laptop is unaffected. Also, applying pressure to the underside of the laptop (pressing in between where the two fans are) stops the issue on the main display.
 
Would love suggestions on how to fix it? My laptop is a 2009, but I'd like to get a few more years out of it.
 
Only recent changes to it where the installation of mavericks about 6 months ago and a ram upgrade made at that same time.
