Overview
The SAAB Information Display (SID) with "missing" pixels. The problem gets worse over time until the display becomes unreadable. The cause is broken and intermittent cable connections between the display and a circuit board. Some displays can be restored by applying pressure to the cable using a rubber band or by resoldering the connections, others have to be replaced. To get access to the ribbon cable, the display has to be removed from the dash and disassembled.
Components
Enclosure
A SID-3 after removal. The plastic case is held in the dash by four snaps, two on the top of the case, and two on the bottom (click picture for more detail). M4 screws were used to pull the SID out of the dash.
Disassembly
Two metal screws and one L-shaped bracket (shown on the right) at the cable connector must be removed. The front and back of the plastic case are held together with small plastic tabs that can be released by pressing down, then the case can be opened and the circuit boards can be slid out.
LCD
Front of the unit (upside down), showing the LCD mounted in a white plastic frame and the analog clock.
Circuit Boards
Back of the unit (still upside down), showing the two circuit boards and the cable connector. The round black object is a piezoelectric buzzer.
Ribbon Cable
The liquid crystal display (LCD) is attached by a flat ribbon cable soldered to the main circuit board.
