1. Unplug the TV.
2. Remove any residual charge from the Vsus and Vda lines. Use a 5W 500 ohms resistor.
3. Measure the resistance between:
• Chassis ground and pin 1 of connector P2 on the P board (Vsus).
• Chassis ground and pin 12 of connector P6 on the P board (P15V).
• Chassis ground and pin 1 of connector P35 on the P board (Vda).
Note: A dead short or a reading lower than 1K indicates a shorted or partially shorted line.
Is there a short
circuit of the Vsus,
P15V, or Vda?

Unplug the TV and reconnect A1. Set your
voltmeter to measure DC voltage. Ground
the negative (Black) lead and place the
positive (Red) lead on pin 10 (F15V) of
connector P6 on the P board. Plug-in the
TV.
