Technical Description
Specification of KEY for DTCP-IP, CI Plus, DIMORA, HDCP2, Netflix, Widevine
General information:
1. NAND FLASH (IC8900) for spare parts has the seed of KEY for each.
2. The final KEY data will be generated by sLD8A IC (IC8000) when SELF CHECK was done and are stored in both
sLD8A IC (IC8000) and NAND FLASH (IC8900).
All KEYs are not generated for all models.
The necessary KEY are only generated and stored depend on the feature of models.
Replacement of ICs:
When sLD8A IC (IC8000) is replaced, NAND FLASH (IC8900) should be also replaced with new one the same time.
When NAND FLASH (IC8900) is replaced, sLD8A 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 the MENU button on the remote
control for more than 3 seconds.
TV will be forced to the factory shipment setting after this SELF CHECK.
