DISPLAY FAULTS

PIXEL FAULT

There are three pixel faults - bright fault, dark fault and flicker fault - that are respectively defined as follows.

BRIGHT FAULT

In this pixel fault, a cell that should not light originally is lighting on and off.  For checking this pixel fault, input ALL BLACK SCREEN and find out the cell that is lighting on and off.

DARK FAULT

In this pixel fault, a cell that should light originally is not lighting or lighting with the brightness twice as brighter as originally lighting.  For checking this pixel fault, input 100% of each R/G/B color and find out the cell that is not lighting.

FLICKER FAULT

In the pixel fault, a cell that should light originally or not light originally is flashing on and off.  For checking this pixel fault, input ALL BLACK SCREEN signal or 100% of each RGB color and find out the cell that is flashing on and off.

MEMORY IC REPLACEMENT

• This model uses the memory IC.
• This memory IC stores data for proper operation of the video and drive circuits.
• When replacing, be sure to use an IC containing this (initial value) data.

MEMORY IC REPLACEMENT PROCEDURE

• POWER OFF:  Switch off the power and disconnect the power plug from the AC outlet.
• REPLACE THE MEMORY IC:  Be sure to use the memory IC written with the initial setting values.
• POWER ON:  Connect the power plug to the AC outlet and switch on the power.

SERVICE MODE SETTING [SYSTEM CONSTANT SETTING]

• Press the  [DISPLAY] key and  [MUTING] key simultaneously, then enter the SERVICE MODE.
• Press the [8] key, then enter the SYSTEM CONSTANT SET SCREEN.
• Check the setting values of the SYSTEM CONSTANT SET. If the value is different, set the correct value with the [FUNCTION ◄/►] key.

RECEIVING CHANNEL SETTING

Refer to the OPERATING INSTRUCTIONS and set the receive channels (Channels Preset) as described.

USER SETTING

Check the user setting items according to the given in page later. Where these do not agree, refer to the OPERATING INSTRUCTIONS and set the items as described.

SERVICE MODE SETTING [ADJUST MODE SETTING]: Verify what to set in the SERVICE MODE, and set whatever is necessary. Refer to the SERVICE ADJUSTMENT for setting.

SERVICE MODE SCREEN

ADJUSTMENT MODE

When the SERVICE MENU SCREEN of SERVICE MODE is displayed, press [1] key to enter the ADJUSTMENT MODE.

NOTE:   * When a number key other than the [1] key is pressed in the SERVICE MODE SCREEN, the other relevant screen may be displayed.

* This is not used in the adjustment procedure. Press the [MENU] key to return to the SERVICE MODE SCREEN.

VSM PRESET MODE

This mode is used to adjust the VSM.

HOW TO ENTER THE VSM PRESET MODE

• When the SERVICE MENU SCREEN of SERVICE MODE is displayed, press [6] key to enter the VSM PRESET MODE.

INITIAL SETTING VALUES

• Perform fine-tuning based on the "initial values" using the remote control when in the Service mode.
• The "initial values" serve only as an indication rough standard and therefore the values with which optimal display can be achieved may be different from the default values.
• [S004] to [S009] are the off set values.

SELF CHECK FEATURE

HOW TO ENTER THE SELF-CHECK MODE

• Press the  [DISPLAY] key and  [MUTING] key simultaneously, then enter the SERVICE MODE.
• Press the [2] key then enter the SELF CHECK MODE.

NOTE:

When a number key other than the [2] key is pressed in the SERVICE MODE screen, the other relevant screen may be displayed.  This is not used in the SELF CHECK MODE. Press the [MENU] key to return to the MAIN MENU SCREEN.

HOW TO EXIT THE SELF-CHECK MODE

• To Save Failure History:

Turn off the power by unplugging the AC power cord plug when in the Self-check display mode.

• To Clear (Reset) Failure History:

Turn off the power by pressing the [POWER] key on the remote control unit when in the Self-check display mode.

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.

POINTS TO NOTE WHEN USING THE SELF CHECK FEATURE

• In addition to circuit failures (abnormal operation), the following cases may also be diagnosed as "Abnormal" and counted.
• Temporary defective transmissions across circuits due to pulse interruptions.
• Misalignment in the on/off timing of power for I2C bus (Vcc) when turning on/off the main power.   Therefore, turn on the main power, and then wait for about 3 seconds before starting Self-check. If recurrences are expected, ensure to clear (reset) the failure history and record the new diagnosis results.

SELF CHECK - DETAILS

If error is detected, the power is turned off. Shortly after the power is turned off, POWER LED will be blinked.  When the protection of low bias line short operates, the power cannot be turned on until the power cord takes out and inserts, after the power is turned off.
