Since it changes with the angle you nailed the diagnosis. Something is losing connection. Start simple with a new cable or cables from the LCD to the main board.
<span id="INSERTION_MARKER">Until a short time after the warranty expiry I had a sharp, crisp screen display. Then it started to deteriorate. <span>
<span>Depending on the position/angle, of the display screen I could see only moving colours and badly blurred characters. In a very few brief instances I could see the original sharp display. It appears to be connected with the movement of the hinges. Every other aspect of the Acer is functioning. <div><span>
<span>Anyone with asimilar problem and a solution? Thanks!
