TROUBLESHOOTING 5.1 SELF-CHECK FEATURE 5.1.1 OUTLINE This model has a “Self-check function”, which checks the operation state of the circuits and informs us of a failure by flashing POWER LED when a failure occurs. Diagnosis is performed when power is turned on, and information input to the main microcomputer is monitored at all time. Failure detection is based on input state of I 2C bus and the various control lines connected to the main microcomputer. SERVICE MENU SCREEN SERVICE MENU 1. ADJUST 2. SELF CHECK 3. I2C STOP 5.1.2 HOW TO ENTER THE SELF-CHECK MODE (1) Press the [INFORMATION] key and the [MUTING] key of REMOTE CONTROL UNIT simultaneously, then the SERVICE MENU screen will be displayed. (See Fig.1) (2) In the SERVICE MENU, press the [2] key. Then, the SELFCHECK MODE screen will be displayed. (See Fig.2) (3) Press the [ZOOM (red)] key, then the second page of the SELF-CHECK MODE screen will be displayed. NOTE: • When the [ZOOM (red)] key pressed, the first page and the second page change screen. 5.1.3 HOW TO EXIT THE SELF-CHECK MODE (1) When you leave the failure history Press the [MENU] key to exit the SELF-CHECK MODE. (2) When you not leave the failure history In the SELF-CHECK MODE, press the [POWER] key. Then the power is turned off. 5.1.4 FAILURE HISTORY Failure history can be counted up to 9 times for each item.When the number exceeds 9, display will remain as 9. Failure history will be stored in the memory unless it has been deleted. NOTE: Only SYNC (with/without sync signals) will be neither counted nor stored.

(1) Temporary defective transmissions across circuits due to pulse interruptions. (2) Misalignment in the on/off timing of power for I2C bus (Vcc) when turning on/off the main power. Diagnosis may be impeded if a large number of items are displayed as “NG”. As such, start self-check only after 5 seconds in the case of panels upon turning on the power. If recurrences are expected, ensure to clear (reset) the failure history and record the new self-check reults.
