Inspection Procedure

  1. CHECK HARNESS AND CONNECTOR (MULTI-DISPLAY - TELEVISION DISPLAY ASSEMBLY) 
    1. Disconnect the multi-display connector M3 and television display assembly connector R14.
    2. Measure the resistance according to the value(s) in the table below.

    Standard resistance 

    RESISTANCE SPECIFICATION

    Tester connection Condition Specified condition
    NTSC - VV+ Always Below 1 Ω
    SGN1 - VV- Always Below 1 Ω
    SLD - SGND Always Below 1 Ω
    NTSC - Body ground Always 10 kΩ or higher
    SGN1 - Body ground Always 10 kΩ or higher

    NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

  2. INSPECT TELEVISION DISPLAY ASSEMBLY (OUTPUT SIGNAL) 
    1. Reconnect the television display assembly connector R14.
    2. Measure the waveform according to the table below.

      OK 

      TESTER CONNECTION AND SPECIFIED CONDITION

      Tester connection Condition Specified condition
      VV+ - Body ground DVD display is ON A waveform synchronized with display signals is output

      HINT:

      The waveform pattern may differ from that shown in the illustration below due to differences in oscilloscope setting. A normal television display assembly operating condition can be determined if any waveform is output.
