3-2. SCREEN (G2) ADJUSTMENT
(FINE ADJUSTMENT)
Fine Mode is recommended to set screen controls to their optimal
condition.  It is necessary to build the simple jig, illustrated below,
using 3-watt resistors.  Please note, that if the proper voltage is not
obtained with their listed values, resistors, then please increase or
decrease one of the values in the resistor network to obtain the
correct voltage.
1. Select VIDEO1 mode without signals.
2. Connect G2 JIG.
3. SW on JIG.
4. Connect an oscilloscope to the TP7101(KR), TP7202(KG) and
TP7301(KB) of CR board, CG board and CB board.
5.  Adjust  R, G and B screen voltage to 177.5 
±
 0.5V with screen
VR on the Focus block.
3-3. DEFLECTION YOKE TILT ADJUSTMENT
1. Connect the color bar generator monoscope pattern to Video 1
input.
2. Cover the both red and blue picture lenses with the lens caps
to show only the green color.
3. Loosen the deflection yoke set screw and align the tilt of the
Deflection Yoke so that the bars at the center of the
monoscope pattern are horizontal.
4. After aligning the deflection yoke, fasten it securely to the
funnel-shaped portion (neck) of the CRT.
5. The tilt of the deflection yoke for red is aligned  in the mode
Cover the both green and blue picture lenses with the lens caps
and the tilt of the deflection yoke for blue is aligned with in
Fig. 3-3
3-4. FOCUS LENS ADJUSTMENT
In this adjustment, use the remote commander in the
service mode.
For details of the usage of the service mode and the remote
commander, please refer the item 3-9. ELECTRICAL
ADJUSTMENT BY REMOTE COMMANDER.
1. Loosen the lens screw.
2. Cover the both red and blue picture lenses with the lens caps
to show only the green color.
3. Turn the green lens to adjust to the optimum focus point with
the crosshatch signal.
4. Tighten the lens screw.
5. Cover the both green and blue picture lenses with the lens caps
to show only the red color.
6. Adjust red CRT lens just the same as green.
7. Cover the both green and red picture lenses with the lens caps
to show only the blue color.
8. Adjust blue CRT lens just the same as green.
9. After adjusting the items 3-5. Focus VR Adjustment, 3-6. 2-Pole
Magnet Adjustment and 3-7. 4-Pole Magnet Adjustment,
adjust again to the optimum focus point.
*
: Every time you press 6, the test signal changes to
“crosshatch+video signal” - “crossbatch+borderline(black)”
- “crosshach(black)” - “dots(black)” - off.
Note: Instead of items 2, 5 and 7, you can cut off the unnecessary
color beams by controlling the service mode 2150P-2 1
RGBS.

3-5. FOCUS VR ADJUSTMENT
1. Set generator to crosshatch.
2. Cover the both red and blue picture lenses with the lens caps
  to show only the green color.
3. Turn the green focus VR on the focus block to adjust to the
  optimum focus point with the crosshatch signal.
4. Cover the both green and blue picture lenses with the lens caps
