Well, I don't know if you're right or not, but you won't find out there. Talk to Acer's tech support or the vendor you bought your laptop from (if you still have a warranty).
I had a problem with my old white Macbook that sounds a lot like the one you say you're having. Over time, the screen would suddenly stop refreshing and gradually turn white. If I gripped one of the sides of the screen hard enough, it would refresh and keep refreshing as long as I held it.
