1.
Unplug the TV.
2.
Remove any residual charge from the Vsus and Vda lines. Use a 5W 500ohms resistor.
3.
Measure the resistance between chassis ground and pin 6 of connector P2 on the PSS board. Also measure the
resistance between chassis ground and pin 1 of connector P35 on the PSS board. (See the picture below for
connectors’ location.)
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 or Vda,?
