Quick Procedure To Check For Short or Low Resistance Condition of
the Vda Line
1.
Make sure the TV is disconnected.
2.
Remove any residual charge from the Vda line by momentarily grounding them through a 500 ohms
resistor (At least 5Watts).
3.
Measure the resistance between chassis ground and the pins indicated on the table below. A dead
short or a reading lower than 1K indicates a shorted or partially shorted line.
Vda
is generated by the Power supply and is only used by the Panel (Panel Drive ICs)
Test points for the Vda can be easily found on the P board. To check for short circuit or low resistance on
this line, follow this procedure:
