Troubleshoot of Picture Problem Check by signal flow

Check by picture/audio signal flow, 1. Is all input abnormal ? / How about audio ? 2. Check the Test Pattern

< symptom > There are KEY data for DTCP-IP of DLNA and the registration information for 

Check the voltage level of HDMI input signal

Bias = 3.0V

video service in IC8902.  And the final KEY data is generated by IC8000 when SELF-CHECK is done.  After that final data is stored in both IC8000 and IC8902. So when IC8000 is replaced, also IC8902 must be replaced. (When IC8902 is replaced, IC8000 is not necessary to be replaced.)

Reboot / Error message (History of R/E counter)

Troubleshoot of Power On Problem with A board(1/2) Check by power on sequence < Difference from last year model > # The new models with the Peaks LD4/Pro4 happen the fast 3 blinks instead of 14 blinks of the previous model. # The EEPROM(IC8502) is integrated to Flash(IC8900). The memory block is separated. After just AC plug in, the Peaks IC accesses to the EEPROM part of IC8900 once (about 300ms*). (The standby power always output to A board, when plug in. ) If the Peaks IC can’t read the IC8900 at that time, fast 3 blinks happened. *The time is different by the model and state.

< symptom > Just AC plug in, SOS fast 3 blinks

Check if TV_SUB_ON signal is output high signal once. (about 300ms)
