1. Minimize the vertical mis-convergence in the center at
the left-most end and at the right-most end of screen
using the DY correction reactors XBV and XCV.
* Because TLV is used for horizontal trapezoidalRB
distortion adjustment, adjust the convergence while

trapezoidal distortion correction only when MSV isRBRB
extremely poor.
2. Minimize the horizontal mis-convergence in the top
and the bottom of screen using the DY correction
reactors YBH and YCH.BG RBBGGRRR GB
3. Minimize the mis-convergence at the left-most endTLVTLH
and at the right-most end of screen using the DYRG

correction reactors APH, TLH and CBH.
4. Adjust the V. STAT BOTTOM data then adjust the V.

(Keep the V.STAT data to be 128, and do not change
it to any data other than 128.)
Note: The V. STATIC BOTTOM and the V. STAT. TOP
adjustment menus are located in the lower layer of
the E board menu of the MAINTENANCE menu.
5. If there exists any left-to-right asymmetrical areas,
insert the TLH correction plate into DY and so that the
mis-convergence is minimized.)

Then confirm the vertical and horizontal convergence
