SU Board Isolation Procedure
To isolate the SU board:
1. Remove the 2 VF_GND screws on the
SU board only.
2. Unplug connector SC41 on the SC
board and SU11 on SU board.
3. Place SC jig cable ZSC09187)between
pins 1 and 2 of connector SC50 on the
SC board.
Note: If the SC jig is not available, install a
jumper between pins 1 and 2 of
connector SC50 on the SC board.
(Remove the jig or jumper after
completing isolation procedure)
Note: This procedure could be useful when
troubleshooting 7 blinks problems.
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.
