Check the logical state of Pin 1 of IC8110. If it is L, check the mounting status of Pin 62 of
IC8201.
Check the mounting and operation statuses of F8102, D8105 and D8106.

If there is no problem with it, IC8108 may be in failure.
• Check the logical state of TP8215. If it is L, check the mounting status of CN8202.
• Check the logical state of Pin 4 of IC8308. If it is L, check the mounting statues of IC8308.
• Check the logical state of Pin 12 of IC8309. If it is L, check the mounting statuse of IC8309.
Input an SDI signal supported by the PRA-BD11 and check the following:
• Check that a 270MHz clock signal with voltage swing from about 3.5-4.0 V is output from
Pins 28 and 29 of IC8103.
• Check that an SDI signal with voltage swing from about 3.2-4.0 V is output from Pins 31
and 32 of IC8103.
Check the mounting and operation statuses of CN8201, R8208, TH8301, and F8301,
in that order.
