Mechanical Instructions
EN 9DPTV585 AA 4.
4. Start the CRT mounting ear screws but do not tighten
them.
5. Tighten the CRT mounting ear screws in a star pattern (like
tightening lug nuts on the wheel of a car). Make sure the
CRT does not shift position from the outline defined in step
B6.
Caution: do not over tighten the CRT ear screws (the CRT
mounting ear screws are not used on some assemblies).
6. Install the CRT mounting bracket and start the four CRT
mounting bracket bolts with springs.
7. Tighten the bolts in a star pattern.
8. Lay the CRT assembly on its side with the plug pointing up.
9. Remove the plug.
10. Using the PTV coupling fluid bottle with the cone top, refill
the coupler with fluid through the drain access hole.
Completely fill the coupler chamber so the fluid is level with
the top of the coupler at the plug. Wipe any excess fluid
from around the coupler.
11. Reinstall the plug and check for any fluid leaks.
12. Install the repaired CRT/optical block assembly into the
PTV and perform any necessary adjustments.
4.4 Set Re-assembly
To re-assemble the whole set, execute all processes in reverse
order.
Note: While re-assembling, make sure that all cables are
placed and connected in their original position
