 Saab Information Displays from 1994–2003 commonly suffer from an electrical system failure that results in some or all of the on-screen liquid crystal display (LCD) pixel lines becoming invisible, rendering the SID difficult to read or, in some cases, entirely unusable.The problem is most often caused not by defective pixels, but by some or all of the LCD's flexible flat cable (ribbon cable) contacts separating from the main logic board.Several third party vendors offer a service to permanently fix broken SIDs, for a fee.
