SC Board Resistance Test
(All Models, Except TC-50PX14, TC-P50C1, TC-P50X1)
Procedure:
Using a digital meter measure the
resistance between the VF-ground screw
(Floating ground) and pin 3 of connector
SC42.
Also measure the resistance between
the VF-ground screw (Floating ground)
and pin 5 of connector SC42 on the SC
board.
The normal resistance for pin 3 is
approximately
2.9
Kilo-ohms and approx.
5.7Kilo-ohms for pin 5.
Note:
A low resistance reading indicates
a defective SC board.
Preparation:
Disconnect AC Power prior to making any disconnection or connection.
Wait at least 2 minutes before the removal of any connector.
Note:
If the power LED continues to blink even after the TV is unplugged, press and hold the power
switch on the TV for a few seconds until the LED turns off.
Unplug connectors SD42, SD46, SU41 and SD11. Out of all 4 floating ground screws on the SU and
SD boards, remove 3 and leave only one in.
