Important:

High Voltage adjustment should
NOT be adjusted in field. This is
adjusted at factory using precise
loads and should NOT

readjusted.

1.4 High Voltage Adjustment (should NOT be

readjusted in field).

Adjustment preparation
(1) Connect High Voltage meter to FBT High Voltage

output. Connect GND of High Voltage meter to CPT
GND or FBT GND.

(2) Check that High Voltage adjustment VR (RH17) is

set to mechanical center. (located behind FBT on
DEFLECTION PWB).

(3) Receive circle pattern signal.
(4) VIDEO control should be reset.

Adjustment procedure
(1) Adjust High Voltage to following spec. by turning VR

RH17 slowly. ADJ. SPEC = 30.2 ± 0.2kV

(2) After adjustment, fix VR RH17 with Silicone glue

(KE40RTV).

2. FINAL ASSEMBLY ADJUSTMENT

2.1 Cut Off Adjustment

Adjustment preparation
(1) Adjust screen VR’s on Focus Pack fully

counterclockwise.

(2) Adjust Focus VR’s on Focus Pack fully

clockwise.

(3) Set video conditions to factory preset.
(4) The vertical incident illumination on the screen

should be 20 lux or less (room should be dark).

Adjustment procedure
(1) Press and hold INPUT key on control panel and

then POWER ON to access I

C adjustment

mode.

(2) Choose “SERVICE” item from I

C adjustment

menu by pressing CURSOR

(3) Screen VR should be turned clockwise gradually

and set so that retrace line begins to appear.

(4) Return to “NORMAL” mode by CURSOR

again.

(5) Adjust Focus VR’s so that focus is even all

around screen.

2.2

DCU Phase Data Setting

Adjustment preparation
(1) Cut off adjustment should be finished.
(2) Set video conditions to factory preset.

Adjustment procedure

(1) Receive any NTSC signal.
(2) Push “SERVICE ONLY” SW on CONV. FOCUS

PWB. (Enter to DCU ADJ. mode).

(3) Push HELP key on R/C. (Green cross hatch is

displayed).

Then push EXIT key on R/C. (Character pattern
is displayed. This is the PHASE setting mode).

(4) Set PH-H phase data as shown below by using

4 and 6 key on R/C.

(5) Set PH-V phase data as shown below by using

2 and 5 key on R/C.

(6) Set CR-H phase data as shown below by using

CURSOR

and

key on R/C.

(7) Set CR-V phase data as shown below by using

CURSOR

and

key on R/C.

(8) Push HELP key on R/C to exit from the PHASE

mode.

(9) Push PIP MODE key 2 times on R/C to write the

phase data to memory.

(10) When Green dots are displayed, push MUTE

key to return to DCU ADJ. mode.

(11) Push “SERVICE ONLY” SW to return to RF or

VIDEO mode.

(12) Receive any 1080i signal (Input to Component

video terminal). Select “Aspect 5” on SET-UP,
PICTURE FORMAT of OSD MENU.
