PVM-14L2/20L2
1. Group of models inch 14 (See Table 2-3.)
1. Input a crosshatch signal.
2. Adjust 4-pole magnet, 6-pole magnet of the deflection
yoke and RV708/C board to minimize mis-conver-
gence.
3. When the mis-convergence of the TILT component is
included in the horizontal convergence, make adjust-
ment with the TLH compensator. (Fig. 2-28)
4. Fix the DY spacer with RTV.
5. Fix the 4-pole magnet, 6-pole magnet and TLH of
deflection yoke by applying paint lock.
2. Groups of models inch 20 (See Table 2-3.)
1. Input a crosshatch signal.
2. Adjust 4-pole magnet, 6-pole magnet of the deflection
yoke and RV708/C board to minimize mis-convergence.
3. When the mis-convergence of the TILT component is
included in the horizontal convergence, insert the TLH
compensator into the deflection yoke for adjustment.
(Fig. 2-28)
4. Fix the DY spacer with RTV.
5. Fix the 4-pole magnet, 6-pole magnet and TLH of
deflection yoke by applying paint lock.

2-13. G2 Adjustment
Conditions
CONTRAST and BRIGHT : PRESET positions
1. Input a (480/60I) all-black signal to the COMPO-
NENT Y IN connector.
2. Select the cathode that shows the highest pedestal level
among the red, green and blue cathodes.
3. Connect probe of an oscilloscope as indicated below.
Adjust RV709 on the C board so that the pedestal level
becomes standard value as shown in Fig. 2-29.
RED : TP701 or KR
GREEN : TP702 or KG
BLUE : TP703 or KB
GND : TP700
Standard value A = 160 ±2 VDC (14 inch)
Standard value A = 150 ±2 VDC (20 inch)
