B-12.
Double check focus performance the letters must be clear, legible and uniform, if not, repeat stape 2.3.2.1 to
obtain best focus performance.
B-13.
Mi sconvergence alignment
B-14.
Select crosshatch pattern and then input individually input R+B and R+G signals then measure and make sure
miscongence within Center = 0. 2 mm(max.)
Zone A = 0.3 mm(max.)
Zone B = 0.4 mm(max.)
, if not, readjust 4 P and 6P on the deflection yoke to get misconvergnce within specification. Preset modes alignment
