・

Connect straightly and completely.

・

Connector of FFC has holding mechanism. Holding part must not be loose.

・

 Connector is not inserted completely.

・

 Connector is not inserted straightly.

・

 Holding part is loose.

      ・

 Jig can be set regardless of presence of C-PWB cover.

■ Adjustment

1 ) Display flicker pattern with service tool.

2 ) Change the value roughly from min. to max. (with [UP+5] or

[DOWN-5] button) and watch display.

3 ) Degree of flicker changes as the value change.

4 ) Search approximate value which flicker is least at center of the dis-

play (with [UP+5] or [DOWN-5] button).

5 ) In addition to above, Search value which flicker is least at the cen-

ter of the display (with [UP+1] or [DOWN-1] button) in detail.

■ Conditions

・

 Viewing distance : 0.35±0.1 [m]

・

 Viewing angle : 0degree and ±45 - 80degree

・

 Criteria : visual observation

■ Background

・

 The way of driving TFT-LCD panel is AC drive to prevent seize.

・

 For example AC drive is that voltage applied to TFT change from +B [V] to 0 [V] in time for 100% signal level. And the reference voltage 

    is +A [V] (=B/2).

・

 0 [V] is not change among TFT-LCD panels.

・

 Though input voltage is +B[V], actual voltage applied to TFT is change among panels.

・

 If the reference voltage is fixed to +A[V], DC may generated. Because difference of voltage (A-0) is not equal to (B-A).

・

 Because DC may occur seize, the reference voltage should be adjusted with dedicated pattern to be center of 0[V] and +B[V].

・

 The reference voltage is called VCOM. VCOM is adjusted in flicker adjustment.

The operating conditions of the Flicker adjustment tool of the informa-
tion display are as follows.

*1 : For PN-R903, you need to use the adjustment tool.  

■ When connected to the information display
with an RS-232C cable

The required RS-232C cable is as shown below. Connect the PC’s 
COM port and the RS-232C input terminal of the display with the cable. 

■ When connected to the information display
with a LAN cable

To use a LAN communication, settings must be made both in the PC side
and in the display side. 
For details of LAN, refer to following description.  

Refer to the Operating Manual.

    ・

  It does not operate normally in the power standby state or the 

             signal standby state. Provide a signal to the current input or 

             set the power management to “NO.”

Press [Flicker Adjustment] button of the service tool launcher and the
following message is displayed. Check to confirm that a jig is installed,
and press [OK] button.

The flicker adjustment procedures by use of the flicker adjustment tool
are as follows:

1 )  Press [Connection Setting] button, and perform the communication

      setting.

2 )  Press [Flicker] button, and the adjustment pattern is displayed 

      on the monitor and [Flicker] button turns to yellow-green color. 

      In addition, the current adjustment value is stored in Reg Value 

     (VCOM value) and [UP+1], [UP+5], [DOWN-1], [DOWN-5], and

     [Write] buttons are enabled.

3 )  When [UP+1] or [UP+5] button is pressed, the Reg Value is 

      increased by 1 or 5 respectively (up to max. 127). When [DOWN-1] 

      or [DOWN-5] button is pressed, the Reg Value is decreased by 1 or 

      5 respectively (up to min. 0). 

1 ) When [Write] button is pressed, the Reg Value is written as the

adjustment value.

2 ) When [Flicker] button is pressed again, the adjustment pattern on

the monitor disappears and [Flicker] button turns to gray color. In
addition, the Reg Value is deleted and [UP+1], [UP+5], [DOWN-1],
[DOWN-5], and [Write] buttons are disabled. 

3 ) When [Exit] button is pressed, the tool is terminated. When the tool

is terminated with the adjustment pattern on the monitor displayed,
the adjustment pattern on the monitor is deleted. 

    ・

  When the tool is used in a LAN connection, if a certain time 

           passes without any operation, the connection is closed.
