Sd Board Isolation Procedure - Panasonic TC-P42X1 Revised Troubleshooting Handbook

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.
To isolate the SD board:
1. Remove the 2 VF_GND screws on the
SD board only.
2. Unplug connector SC42/SU42,
SC46/SD46, and SU11/SD11 from the
SD board.
3. Place SC jig cable (TZSC09187)
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.
