Maintenance— 2213 Service
4.
Remove the AUTO FOCUS control-knob shaft
assembly by pulling it straight out from the front panel.
5.
Remove the POWER switch extension-shaft push
button assembly by first pressing in the POWER button to
the ON position. Insert a scribe or similar tool into the notch
between the end of the switch shaft and the end of the
extension shaft and gently pry the connection apart. Push
the extension shaft forward, then sideways, to clear the
switch shaft. Then pull the extension shaft back and out of
the instrument.
6.
Disconnect the leads of L925 (inductor), the lead of
the fuse holder, the lead of the power-cord connector, and
four leads (P801, P802, P803, and P804 from the Current
Limit board) from the Main circuit board.
7.
Unsolder the rear-panel EXT Z AXIS connector wire
from the Main circuit board.
8.
Unsolder two sets of crt socket wires from the Main
circuit board, noting wire color and position for reinstallation
reference.
9. Unsolder two sets of delay-line wires from the Main
circuit board, noting wire color and position for reinstallation
refrence.
10. Remove two screws securing the power-supply
transistor heat-sink assembly to the right side of the frame.
11.
Remove three screws securing the Main circuit
board to the instrument frame (one under the EXT Z AXIS
connector and two along the left side of the Main circuit
board).
12. Use a vacuum-desoldering tool to unsolder the 39
interconnecting wire straps (connecting the Main circuit
board to the Front-Panel circuit board) from the Main circuit
board.
N O TE
If a vacuum-desoldering tool is not available, lift each
wire strap out o f the M ain circuit board as its jo in t is
heated. Use care to maintain, as nearly as possible,
the original shape and spacing o f the wire straps to
facilitate replacing the circuit board.
13. Push the wire-strap connection end of the Main
circuit board down until it is clear of the wire strap ends;
then remove it through the bottom of the instrument frame.
Ensure that the interconnecting wire straps are not bent out
of place.
14.
Unsolder the delay-line holder tabs from the Main
circuit board.
To replace the Main circuit board, use the following
procedure:
15.
Insert the delay-line holder tabs into the replacement
circuit board and solder them in place. Ensure that the hold
in the front tab and the mounting hole in the circuit board are
aligned.
16.
Place the Main circuit board into the chassis frame,
ensuring that the board is in the guides at the rear and right
side of the frame.
17.
Reinstall three screws securing the Main circuit
board to the frame (removed in step 11).
18.
Reinstall two securing screws in the power-supply
transistor heat-sink assembly (removed in step 10).
19.
Move the front part of the Main circuit board into
position. Align the 39 wire straps and insert them into their
corresponding holes while maintaining their original shape
and spacing.
20. Resolder the wire straps to the Main circuit board.
21.
Resolder two sets of delay-line wires at the location
noted in step 9.
22.
Resolder two sets of crt socket wires at the
locations noted in step 8.
23.
Insert and resolder the EXT Z AXIS connector wire
into the Main circuit board.
24.
Reconnect the leads of L925 (inductor), the fuse
holder, the power cord connector, and four wires from the
Current Limit board (removed in step 6).
25.
Insert the POWER switch extension-shaft push
button assembly into the front panel (from the rear). Use a
flat-bit screwdriver to hold the POWER switch shaft fully in
and align the extension shaft with the switch shaft. Press
them together gently until they snap into position.
26.
Reinstall the AUTO FOCUS knob shaft assembly
(removed in step 4).
