13. Convergence Adjustment
CH : Convergence error of horizontal direction
CV : Convergence error of vertical direction
(1) Receive signal 14 (Cross hatch pattern).
(2) Measure convergence error. If it is out of spec, adjust convergence by 4-pole magnets and 6-pole
magnets.
A Zone (A circle 236mm in the center of the CRT face center)
CH, CV : Within 0.25mm
B Zone (Areas outside of zone A within the rectangle of 315mmx236mm)
CH, CV : Within 0.35mm
14. Power Saving Function Inspection
(A) Mode: No.20
(B) Pattern: Full white
(C) Input voltage: AC240V/50Hz
