Vertical Raster Shift Adjustment; Initial Center Static Convergence - Panasonic CT-30WX54J Service Manual

Fully degauss the receiver by using an external degaussing coil.
Slide the deflection yoke back and forth on the neck of the CRT until it produces a near white,
uniform raster.

VERTICAL RASTER SHIFT ADJUSTMENT

Apply a green pattern with a horizontal line, adjust the Deflection Yoke so that has no tilt, then secure
it.
Adjust center line of the pattern with the mechanical center of the CRT, this center is determined by
two marks at the side edges of the screen. To adjust the line, once the vertical raster shift tabs are
place at 3 oclock to reduce itsmagnetic field effect open the tabs the same angle from the center, until
the center line of the pattern becomes a straight line, centered with the marks of the CRT.
IMPORTANT NOTICE
Rings come along with deflection yoke in one piece.

INITIAL CENTER STATIC CONVERGENCE

Connect a dot/cross hatch generator to the receiver and tune in a signal. Observe misconvergence at
center of the screen only.
Adjust the R&B pole magnets; by separating tabs and rotating to converge blue with red.
Adjust the R&B and R&B&G pole magnets: by separating tabs and rotating to converge blue and red
(magenta) with green.
NOTE
Precise convergence at this point is not important.
