I have this 17" Acer laptop that the screen goes light and sketchy. I can tap on the space between the keys and the screen and it will come back to normal color and stay a while and then revert back to it's old ways. Anyone had this problem or know how I can fix it. I feel that it is a loose something in there but haven't opened it. I'm a little scared, I guess. Sedrick

Acer is well known for these sort of problems with laptop screens, beside hinges (these tend to crack and eventually break down very quickly).
You will need to sent your laptop back to Acer for repair as they will swap the whole screen for you. If the laptop is older you may consider it not to send as they charge horrible prices for after warranty repairs and they will not tell you how much it will cost before you send your laptop for examination.
Sorry, for bad news. I can give you few personal stories on Acer topic, I'm one of unhappy customers and I will never ever buy from them
