Part number:
TZSC09187

Caution: Remove SC jig from SC board after inspection.

connecting with SD board. The board will be damaged.)

3. Turn on the TV/Display Unit and confirm the power LED blinking.

LED blinking: Possible cause of failure is in SC board

4. After inspection, turn off the TV/Display Unit and wait a few minutes to discharge.
