Chapter 4---Maintenance (Removal/Replacement)
Figure 4-7. Convergence/Deflection PCB.
4. Loosen (not necessary to remove) the 5 screws that
secure the Convergence Deflection PCB to the electronic
module card cage (
see Figure 4-7) .
5. Remove the Convergence Deflection PCB by sliding it
upward so the mounting screws will clear the access
holes, then angle the right side outward.
NOTE: In order
to get the right side out, it may be necessary to first move
the board out enough to clear the access holes,
then
angle the left side out just enough for the top 2 fins of the
heat sync to fit over the electronic module frame lip (this
will allow a little more clearance for the right side to be
removed),
then maneuver the right side out.
6. Reinstall the Convergence/Deflection PCB by lowering
the right side in first until it clears the electronic module
edge, then lowering the left side in.
NOTE: it may be
necessary to fit the top 2 fins of the heat sync over the
electronic module frame lip at the left to get enough
clearance for the right side to be installed. Carefully fit the
board over the mounting screws and slide the board into
position. Tighten the screws and reconnect the
connectors.

The Horizontal/Vertical (H/V) Deflection PCB is located in the upper
portion of the Electronic Module card cage.
