Maintenance— 2230 Service
9. Perform
the
"Power-Supply
Shield”
removal
procedure.
10. Unsolder two wires from the Main circuit board to
the Filter circuit board.
11.
Unsolder the rear-panel EXT Z AXIS connector
wire from the Main circuit board.
12.
Unsolder the two leads on the Main circuit board
from the fan driver.
13.
Unsolder the three leads on the chassis mounted
CR970 from the Main circuit board.
14.
Disconnect P9070, a three-wire connector from the
Main circuit board to the heat-sink mounted Q9070.
15.
Remove the FOCUS control shaft assembly by pul
ling it straight out from the front panel.
16.
Remove the
POWER
switch extension-shaft
assembly by first pressing in the POWER button to the
ON position. Then 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. Finally, pull the extension shaft back and
out of the instrument.
17.
Remove two recessed screws securing the power-
supply transistor heat-sink assembly to the right side of
the chassis frame.
W A R N I N G
The crt anode lead and the output terminal to the
High-Voltage Multiplier will retain a high-voltage
charge after the instrument is turned off. To avoid
electrical shock, ground the crt side of the anode
lead to the main instrument chassis.
18. Disconnect the crt anode lead from the High-
Voltage Multiplier anode lead by carefully pulling the anode
plug out of the jack. Discharge the plug tip to the chassis.
19. Unsolder two sets of crt socket wires from the
Main circuit board, noting wire color and position for rein
stallation reference.
20.
Unsolder two sets of delay-line wires from the Main
circuit board, noting wire color and position for reinstalla
tion reference.
21.
Remove three screws securing the Main circuit
board to the instrument chassis frame (one under the EXT
Z AXIS connector and two along the left side of the Main
circuit board).
22.
Use a vacuum-desoldering tool to unsolder the 45
wire straps (W9001) connecting the Main circuit board to
the Front-Panel circuit board) from the Main circuit board.
NOTE
If a vacuum-desoldering tool is not available, lift each
wire strap out of the Main circuit board as the joint
is heated. Use care to maintain, as nearly as possi
ble, the original shape and spacing o f the wire straps
to facilitate replacing the circuit board.
23.
Push the wire-strap connection end of the Main cir
cuit board down until it is clear of all wire strap ends; then
remove it through the bottom of the instrument frame.
Ensure that the wire straps are not bent out of place.
NOTE
When installing the Main circuit board, ensure that
the circuit board is in the guides at the rear and right
side of the frame and that the 45 wire straps of
W9001 are inserted into their corresponding holes.
To reinstall the Main circuit board, perform the reverse
of the preceding steps.
