Unplug the three PCB-CRTs. 4. Remove 4 screws "a" retaining the Optical Unit. [Figure 1] 5. Remove 4 screws "b" retaining the Lens of the respective CRT 6. Lift the Optical Unit from the Light Box and set it lens down on a flat surface. 7. Remove 4 screws "c" retaining the CRT. [Figure 2] Note: DO NOT loosen the spring loaded screws. Doing so will break the seal between the C-Element and the # 6 Lens, causing leakage of the CRT Coolant. 8. Remove the Deflection Yoke from the neck of the CRT. [Figure 3]
