High voltage check
1. Select an active TV channel and confirm that horizontal is in sync.
2. Adjust BRIGHTNESS and CONTRAST using PICTURE icon menu
so video just disappears.
3. Using a high voltage meter confirm that the high voltage is 27.70 ±
1.25kV for 20” models and 29.25 ± 1.25kV for 25” models.
11. Purity and convergence procedure
Adjustment is necessary only if the CRT or the deflection yoke is replaced or if the setting was
disturbed. The complete procedure consists of:
1. Vertical raster shift adjustment.
2. Initial static convergence.
3. Setting the purity.
4. Final static convergence.
WHEN THE CRT OR THE YOKE IS REPLACED
For 2 piece assembly:
Position purity/convergence assembly as shown and tighten clamp
snugly. Remove the hot-melt glue seal on assembly and position
like tabs of purity device together at 12 o’ clock to reduce its
magnetic field effect.
