Safety Notice
Safety Precautions
The following precautions must be observed.
1:Comply with all caution and safety-related notes provided on the cabinet back, cabinet bottom, inside the cabinet or on the chassis.
2:When replacing a chassis in the cabinet, always be certain that all the protective devices are installed properly, such as, control knobs, adjustment covers or shields, barriers, etc..
DO NOT OPERATE THIS TELEVISION WITHOUT THE PROTECTIVE SHIELD IN POSITION AND PROPERLY SECURED
3:Before replacing the cabinet cover, thoroughly inspect the inside of the cabinet to see that no stray parts or tools have been left inside.
Before returning any televison to the customer, the service personnel must be sure that it is completely safe to operate without danger of electrical shock.
Product Safety Notice
Product safety should be considered when a component replacement is made in any area of a receiver. Components indicated by mark
in the parts list and the schematic diagram designate components in
which safety can be of special signicance.
It is particularly recommended that only parts designated on the parts list in this manual be used for component replacement designated by mark
. No deviations from resistance wattage or voltage ratings may be made for replacement items designated by mark
.

Service Adjustments
CAUTION !
Do not attempt to adjust service adjustments not listed below otherwise it may cause loss of performance
and for correct operation.
r Setting the Initial data
This adjustment is controlled by the CPU (IC5500) through the IIC Bus Data Line in the chassis, and those
adjustment data are memorized the memory IC (IC5750). Therefore, Main board or the memory IC (IC5750)
is replaced, these data will be disappeared. Readjust should be made. Initial data is provided in the CPU
ROM, when the memory IC (IC5750) is replaced with new one. CPU ROM data is loaded into the memory.
Initial data is provided to operating the monitor basically. For operating the monitor quality performance,
further adjustment is required following chassis electrical adjustment.
1. Receive good quality signal.
2. Enter the Service Mode.
3. ADC ADJUST and W/B ADJUST should be readjusted. And Confirm other data value to be the same
as the Service Adjustment Data Table. If it is different, change to correct data
4. Exit the Service Mode.
