The adjustment is carried out on four screens; Wide, S.Live,
Cinema, S.title in both PAL and NTSC modes. When making
the adjustments, feed an external signal to make an
synchronization.

The convergence circuit is a circuit to eliminate screen distortion
and can not make a drastic correction such as to correct entire
