  CAUTION! - Heat sink on IC5004 is -15V.  Care must be 

taken not to allow heat sink to touch any other components.

  Lift lever on front bracket to release and gently pull the back 

chassis assembly away from the bezel.

 

Pull up and rotate both the A and D Boards in order to service 
the unit.

 

When plugging in connector from HM Board to B Board at 
CN3603 insure two brown wires are facing upward towards 
neck assembly.

1.  Discharge the anode of the CRT and remove the anode 

cap.

2.  Unplug all interconnecting leads from the defl ection yoke, 

neck assembly, degaussing coils and CRT grounding 
strap.

3. Remove the Sub-Woofer Assemblies.

4.  Remove the CX Board from the CRT.

5.  Remove the chassis assembly.

6.  Loosen the neck assembly fi xing screw and remove.

7.  Loosen the defl ection yoke fi xing screw and remove.

8.  Place the set with the CRT face down on a cushion and 

remove the degaussing coil holders.

9.  Remove the degaussing coils.

10. Remove the CRT grounding strap and spring tension 

devices.

11. Unscrew the four CRT fi xing screws [located on each 

CRT corner] and remove the CRT  [Take care not to 
handle the CRT by the neck].

WARNING: High voltage remains in the CRT even after the power is disconnected. To avoid electric shock, discharge CRT before attempting to 
remove the anode cap. After removing the anode cap, short circuit to either the metal chassis, CRT shield, or carbon painted on the CRT. 

NOTE: After removing the anode cap, short circuit the anode of the picture tube and the anode cap to either the metal chassis, CRT shield or carbon 
painted on the CRT.

Turn up one side of the rubber cap in 
the direction indicated by arrow a .

Use your thumb to pull the rubber 
cap fi rmly in the direction indicated 
by arrow b .

When one side of the rubber cap separates from 
the anode button, the anode cap can be removed 
by turning the rubber cap and pulling it in the 
direction of arrow c .

1.  Do not use sharp objects which may cause damage to the surface of the anode 

cap. 

2.  To avoid damaging the anode cap, do not squeeze the rubber covering too 

hard. A material fi tting called a shatter-hook terminal is built into the rubber. 

3.  Do not force turn the foot of the rubber cover. This may cause the shatter-hook 

terminal to protrude and damage the rubber.

Preparation:
•  Use cross hatch signal to rough adjust focus, G2 and then input a 

white pattern signal.

•  Face the picture tube in an East or West direction to reduce the 

infl uence of geomagnetism.

•  Confi rm data in service mode to match with CRT screen size.

 • CXA2170D-4

 

•  CXA8070 (Should be set to default)

 

•  VCEN, VPIN, HTPZ, PPHA, VANG, LANG, VBOW, LBOW  
(Should be set to default value).

1.  Input white pattern from pattern generator.  Set the PICTURE control 

to maximum, and the BRIGHTNESS control to standard.

2.  Loosen the defl ection yoke mounting screw, and set  the purity 

control to the center as shown below:

Purity Control

3.  Input a green pattern from the pattern generator.

4.  Move the defl ection yoke backwards, (See Figure 1) and adjust with 

the purity control so that green is in the center and red and blue are 
even on both sides. 

Blue

Red

Green

5.  Move the defl ection yoke forward, and adjust so that the entire screen 

becomes green. 

Figure 1

6.  Switch over the raster signal to red and blue and confi rm the 

condition.

7.  When the position of the defl ection yoke is determined, tighten it with 

the defl ection yoke mounting screw.

8.  If landing at the corner is not right, adjust it by using the disk 

magnets.

The following adjustments should be made when a complete 
realignment is required or a new picture tube is installed. 

These adjustments should be performed with rated power supply 
voltage unless otherwise noted.

The controls and switch should be set as follows unless otherwise 
noted:

VIDEO MODE:  STANDARD (RESET)

 

1.  Beam Landing

 

2.  Convergence

 

3.  Focus

 

4.  Screen (G2)

 

5.  White Balance

 

1.  Color Bar Pattern Generator

 

2.  Degausser

 

3.  DC Power Supply

 

4.  Digital Multimeter

Preparation:
•  Input a cross hatch pattern signal.

•  Set Video Mode to: Standard (Reset)

•  For all 4X3 CRT, VPIN data has separate register for full and V-

compress. Adjust both modes if needed.

1.  Adjust service mode CXA2170D-1 05 V-CEN so that the top pin and 

bottom pin are symmetrical from top to bottom.

2.  Adjust service mode CXA2170D-1 06 V-PIN so that the top pin and 

bottom pin are symmetrical from top to bottom.

3.  Horizontal lines should be straight from left to right.  Check landing for 

side effect.

Preparation:
•  Set the CONTRAST and BRIGHTNESS control to standard (reset).

•  Input a cross hatch pattern signal.

1.  Disconnect the dynamic convergence before adjusting static 

convergence (CN903), except for minor touch-up.

2.  Adjust H.STAT convergence, RV9001, to converge red, green, and 

blue dots in the center of the screen.

3.  Connect dynamic convergence back. 

4.  Adjust V. STAT magnet to converge red, green and blue dots in the 

center of the screen.

The respective dot positions result from moving each magnet interact.  
Perform the following adjustments while tracking.

1.  Use the BMC tabs to adjust the red, green and blue dots so that 

they line up at the center of the screen (move the dots in a horizontal 
direction).
