SERVICE MANUAL
COLOUR VIDEO MONITOR
BASIC CHASSIS
S1
According to a monitor’s installation condition, it may be influenced by a magnetic field and
irregular colour may be caused.
In order to avoid this, the landing(irregular colour) correction function was added.
Therefore, the SIGNAL INPUT PWB is changed because a landing coil is added and a correction
circuit is supported.

■ NOTICE IN REPLACING MEMORY IC
•The previous memory IC cannot be used for a new CPU with landing correction function.
•Be sure to use a new memory IC for a new CPU.
•Since a new CPU is programmed to be upper-compatible with the previous circuit, use a new CPU together
with a new memory IC.
