Warning: Disconnect AC Power prior to
making any disconnection or connection.
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.
Remove the front cabinet and expose the panel to a bright light for a thorough visual inspection. Check for
cracks and blown pixels or any other abnormalities.
Check the ICs on the SU and SD boards for blown hole on the surface.
Note: In some models it is not possible to check if these ICs are blown because they use surface-mount
heat sinks that are glued to the surface of the ICs.
