1. EEPROM (IC8902) for spare parts has the seed of KEY for each. 
2. The final KEY data will be generated by sLD2 IC (IC8000) when SELF CHECK was done and are stored in both sLD2 IC     
    (IC8001) and EEPROM (IC8902). 
    Three KEY are not generated for all models. 
    The necessary KEY are only generated and stored depend on the feature of models. 
 

When sLD2 IC (IC8000) is replaced, EEPROM (IC8902) should be also replaced with new one the same time. 
When EEPROM (IC8902) is replaced, sLD2 IC (IC8000) is not necessary to be replaced the same time. 
After the replacement of IC, SELF CHECK should be done to generate the final KEY data. 
How to SELF CHECK: While pressing [VOLUME ( - )] button on the main unit, press [STATUS]         button on the remote 
control for more than 3 seconds. 
TV will be forced to the factory shipment setting after this SELF CHECK.
