Mechanical Instructions
4.4.8 Large Signal Panel (LSP) 1. Remove the SSB (see paragraph 'Small Signal Board,SSB' above). 2. Remove the Auto-Scavem assy (see paragraph 'Auto Scavem Assy/Panel' above). 3. Disconnect the necessary cables. 4. Release the fixation clamps on the left of the LSP-bracket (the board hinges at the right side). 5. Remove the board from the bracket.

1. Release the two fixation clamps (rather difficult to reach), by pushing them upwards [1]. At the same time, pull the complete assy backwards [2]. Note: be aware that the degaussing coil can hamper this. 2. Release the two fixation clamps on the two sides of the bracket (the board hinges at the connector side). 3. Remove the board from the bracket. 4. When the light guide (sitting in the cabinet, in front of the LEDs) is defective, you can replace it by pushing it forwards at the left side (it hinges at the right side, seen from the rear). 4.4.4 DAF Assy/Panel

Set Re-assembly
To reassemble the whole set, do all processes in reverse order. Be sure that, before the rear cover is mounted: � The mains cord is mounted correctly in its guiding brackets. � All wires/cables are returned in their original positions. This is very important due to the large 'hot' area of the set

1. Remove the fixation screw [1] (if present). 2. Push down the fixation clamp [2], and pull the complete bracket at the same time away from the CRT [3]. The module is now free from the LSP-bracket. 3. Release the fixation clamps [4], in order to remove the print from its bracket. 4.4.5 Double window, PIP panel (If present) 1. It is not necessary to remove the Double window bracket. 2. To remove he Double window PWB, release both upper clamps and take out the PWB. 4.4.6 Auto-SCAVEM Assy/Panel This panel is placed on the left side of the SSB (See figure 'Service Position 2'). Because most of its components are placed on the bottom side, you must lift the panel from its bracket before you can measure it. 1. Therefore, release the two fixation clamps at the top side. 2. Lift the panel from the bracket (it hinges at the bottom). To remove the bracket: 1. First, remove the panel from the bracket, as described above. 2. Then, remove the two fixation screws at the bottom. 3. Lift the Auto-Scavem bracket slightly up, and at the same time bend the top a little away from the tuner. 4. Now, push the bracket into the direction of the CRT, and lift it out of the LSP-bracket. 4.4.7 Small Signal Board (SSB) See paragraph 'Small Signal Board (SSB)' above.
