I've had this all in one Acer A5600U for less than three years, and suddenly while I'm typing in a word document the screen goes haywire -- to make long story short, there's a horizontal line across the screen around two thirds of the way down, with the icons in the top quarter of the screen duplicated as a shadow over the bottom quarter of the screen. Can still get to the underlying icons, but local computer repair shop says LCD is shot and isn't replaceable by manufacturer. And of course my unit is out of warranty. Each of my previous computers has lasted 8+ years without a problem. This is really a disgrace. Help!
