[2] LED flashing specification at the time of the error
Display method
• Refer to Table 1.
• Make the OPC LED flash using the [MENU] key on the remote control since the display for service persons is identified by the number of flashings
(once to 5 times).
Even if the [MENU] key is pressed again, it does not return to the display for customers (only the power LED flashes).
• After recovering from an error, if the same error cannot be generated again, refer to MONITOR ERR CAUSE on the adjustment process screen.
LED flashing method
• Synchronize the phases of the power LED and OPC LED.
• If the LEDs have different number of flashings, adjust the flashing cycle to that where the LED flashes more times.
Table 1. Concrete flashing pattern
* 1: For details, refer to ERROR STANDBY CAUSE on the adjustment process screen.

2. While holding down the “VOL (+)” and “P (
)” keys on the set at once, plug in the AC power cord to turn on the power.
If you fail to boot-up TV, retry the procedure.
