CHECK HARNESS AND CONNECTOR (TELEVISION DISPLAY ASSEMBLY - VIDEO TERMINAL)

Disconnect the connectors from the video terminal and television display assembly.

Measure the resistance according to the value(s) in TESTER CONNECTION SPECIFIED CONDITION .

Standard resistance:

TESTER CONNECTION SPECIFIED CONDITION

Tester connection	Condition	Specified condition
CE - OPEN	Always	Below 1 Ω
NTSC - NTS4	Always	Below 1 Ω
SGND - SGN5	Always	Below 1 Ω
NTSC - Body ground	Always	10 kΩ or higher
SGND - Body ground	Always	10 kΩ or higher

INSPECT VIDEO (VIDEO ADAPTER) TERMINAL

Reconnect the video (video adapter) terminal connector.

Measure the waveform according to TESTER CONNECTION SPECIFIED CONDITION .

OK:

TESTER CONNECTION SPECIFIED CONDITION

Tester connection	Condition	Specified condition
NTSC - SGND	External device is playing	A waveform synchronized with display signals is output

HINT:

The waveform pattern may differ from that shown in Fig 3 due to differences in oscilloscope setting. A normal video terminal operating condition can be determined if any waveform is output.

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
