White screen on laptop

[victoryone45]

Recently the lcd screen on my laptop has been flickering with horizontal lines and turning white. The screen does go back to normal but it takes 10 minutes or more. I checked all the connections inside of the laptop and they are all connected. I was wondering if there is any way to fix this problem.Someone suggested there might be something wrong with the RAMDAC, could this be the issue or is it something else?

Thanks for your responses ahead of time.

I turned down the brightness and it seems to have fixed the problem. The screen has come back on and has not gone off since i did this.
