ADJUSTMENTS IN THE SERVICE MODE

Since some chassis circuit adjustments are controlled by the CPU built into the chassis, adjustments can now be
made by inputting data directly via the remote control handset supplied with the set.
Memory IC replacement
Since adjustment data for the circuit is stored in the memory IC (IC802) that comes with the CPU, the adjustment
data must be re-input when the memory IC is replaced.
(After memory IC replaced, reference data is initially written automatically to memory from the CPU ROM for basic
set operation.)
1. Setting of the service mode.
To enter service mode, press and hold the SERVICE key on
the front control panel, then press the Function button on
the remote control handset.
2. Screen display of the service mode.
Adjustment items can be selected by pressing the Prog.
up/down button on the remote control handset.
Adjustment data can be set by pressing Level
up/down button on the remote control handset.
3. To exit from the service mode.
To exit from the service mode, turn off the TV set by
pressing the power on/off button on the TV set or
