Assy/Panel Removal
Rear Cover Warning: Disconnect the mains power cord before you remove the rear cover. 1. Remove the screws, which secure the rear cover. The screws are located at the top, bottom, left and right sides; next to the Side/IO connections and SCART connection. There are also three deeper located screws next to the stands. 2. Lift the rear cover from the cabinet. Make sure that wires and flat foils are not damaged during cover removal.

1. Remove the middle fixation screw (1) from the bottom side of the connector plate (as this holds the SSB bracket). Note: Sometimes it is easier to loosen the complete connector plate and remove it together with the SSB. 2. Remove all connector fixation screws (2) from the front side of the connector plate. 3. Remove the two female screw locks (3) of the VGA connector. 4. Release the plastic cable clips (4) on the shielding and disconnect all cables from the SSB. Note: Be careful with the fragile LVDS connector on the SSB. 5. Now, completely remove the SSB (together with all the shieldings) from the set. 6.
