Troubleshooting 7 Blinks Failure
Slide 48
Cautions: Disconnect the AC Power prior to making any disconnection or connection.
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.
When taking voltage reading, place the voltmeter probe at the test point, component, or connector’s pin
indicated before connecting the TV to the AC line. This will ensure voltage reading accuracy before the
TV shuts down. (Since the TV is shutting down, expect the voltage to only come up a couple of seconds.)
Preparation:
Disconnect AC Power prior to making any disconnection or connection.
Wait at least 2 minutes before the removal of any connector.
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 for burnt panel driver ICs on the SU and SD boards.
If the panel is defective, the SU, SD, and/or the SC board may also be defective.
Warning: The Vsus line has large capacitors that hold the charge for some time even after the TV has been turned off and
unplugged. When disconnecting P2/SC2 or P11/SS1, bleed the remaining charge of the Vsus before reconnecting the
cable.
Use a 500 ohms/ 5W (At least) resistor to discharge the Vsus line before reconnecting P2/SC2 or P11/SS11.
