screen goes completely white
I purchased my Acer Iconia B1-730HD-17A4 7-Inch HD Tablet with Intel Atom processor 5 months ago. Worked great until recently. My screen will all of a sudden start going white in the corners then gradually the entire screen goes white. I have to click the on button to get it working but then it fades out again. This happens indoors or outside, so not a hot\cold sensitivity issue. Very frustrating. Whats causing this?
