Inspection Procedure

CHECK HARNESS AND CONNECTOR (MULTI-DISPLAY - TELEVISION DISPLAY ASSEMBLY)

Disconnect the multi-display connector M3 and television display assembly connector R14.

Measure the resistance according to the value(s) in the table below.

Standard resistance

TESTER CONNECTION SPECIFIED CONDITION REFERENCE CHART

OK: Go to next step

INSPECT TELEVISION DISPLAY ASSEMBLY (OUTPUT SIGNAL)

Reconnect the television display assembly connector R14.

Measure the waveform according to the table below.

TESTER CONNECTION SPECIFIED CONDITION REFERENCE CHART

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.

Reference: Oscilloscope waveform
1. Terminal: VV+ - Body ground
  Setting: 200 mV/DIV., 10 μs/DIV.
  
  Condition: DVD display is ON.
