Laptop Screen Funky Colors and Horizontal Line Flickers

[frustrated mamma]

Hi I have a Toshiba Satellite M645 with a laptop screen that has recently become strangely colored and has flickering horizontal lines throughout the screen. A screen shot turns out perfect. A few months ago when it happened I rolled back the drivers and it resolved. Not working this time. I also recently had the hard drive replaced, wondering if the video cable could be loose?

Hi, it's a good thing to check, if you have a bad contact from the connector, you will have definitely a bad screen.

are there any other possibilities. any advice for opening up my laptop?
