Before starting convergence adjustments:

1  Perform FOCUS, VLIN and VSIZE adjustments.

2.  Set BRIGHTNESS control to minimum.

3.  Feed in dot pattern.

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

center of the screen (Vertical movement adjust V.STAT RV701 to 
converge).

2.  Tilt the V. STAT magnet and adjust static convergence to open or close 

the V. STAT magnet.

 

When the V. STAT magnet is moved in the direction of arrow a and b, 

red, green, and blue dots move as shown below:

If the blue dot does not converge with the red and green dots, peform 
the following:
1.  Move BMC magnet (a) to correct insuffi cient H.Static convergence.

2.  Rotate BMC magnet (b) to correct insuffi cient V.Static convergence.

3.  In either case, repeat Beam Landing Adjustment.

3.  Set DCOL to “0”.

4.  Set the PICTURE and BRIGHTNESS to minimum.

5.  Adjust with SBRT if necessary.

6.  Select GCUT and BCUT with  1  and  4  .

7.  Adjust with  3  and  6  for the best white balance.

8.  Set the PICTURE and BRIGHTNESS to maximum.

9.  Select GDRV and BDRV with  1  and   4 .

10. Adjust with  3  and  6  for the best white balance.

Note: The following adjustments should always be performed when 
replacing the following components, which are marked with Y on the 
schematic diagram on the A Board:

 

 A BOARD:  IC001,IC602, R030, R625, R626, 
R632, R633, R635, R636, R637, R638, R639

 

1.  Supply 130 +2.0 / -0.0V to the set with a variable auto transformer.

2.  Input a dot signal.

3.  Set the PICTURE  and the BRIGHTNESS controls to minimum.

4.  Set to Service Adjustment Mode.

5.  Select PADJ with  1  and  4  .

6.  Adjust with  6  to the 0 level.

7.  Confi rm the voltage of A Board TP-600 is <125 VDC.

8.  If step 7 is not satisfi ed, replace the components listed above, then 

repeat the above steps.

9.  Supply 130 +2.0 / -0.0V to the set with a variable auto transformer.

1.  Turn the POWER switch ON.  Input a white signal and set the 

PICTURE and BRIGHTNESS controls to maximum.

2.  Confi rm that the voltage between C574 (+) and ground is more than 

99.8 VDC when set is operating normally with 120 +/- 2 VAC. 

1.  Connect the current meter between Pin 11 of the FBT (T504) and 

the PWB land where Pin 11 would normally attach (See Figure 1 on 
the next page).

2.  Input a dot signal and set PICTURE and BRIGHTNESS to minimum: 

IABL = 95 + 100/-95µA.

3.  Confi rm the voltage of A Board TP-600 is 117 ± 0.3 VDC.

4.  Connect the digital voltmeter and the DC power supply via Diode 

1SS119 to C574 (+) and ground (See Figure 1 on next page).

5.  Increase the DC power voltage gradually until the picture blanks out.

6.  Turn DC power source off immediately.

7.  Read the digital voltmeter indication (standard: less than or equal to 

127.3 VDC).

8.  Input a white signal and set PICTURE and BRIGHTNESS to 

maximum: (standard: less than or equal to 127.3 VDC).

9.  Repeat steps 4 to 7.
