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

- INSPECT TELEVISION DISPLAY ASSEMBLY (OUTPUT SIGNAL)
- Reconnect the television display assembly connector R14.
- Measure the waveform according to the table below.
OK
TESTER CONNECTION AND SPECIFIED CONDITIONTester 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
- Terminal: VV+ - Body ground Setting: 200 mV/DIV., 10 μs/DIV. Condition: DVD display is ON.
NG: REPLACE TELEVISION DISPLAY ASSEMBLY
OK: PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
