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.)

The adjustments in the service mode are listed below table.
The data in each adjustment item is set with the best setting value in the CPU ROM as initial data.
As the shaded adjustment items are adjusted for each TV set individually, it may slightly differ to the initial data.
When the memory IC is replaced, these adjustments should be readjusted according to service mode adjustments
