SERVICE MODE AND SOFTWARE UPDATE  ADJUSTMENTS 

ADJUSTMENT
 ADJUSTMENT PROCEDURE
Entering and exiting the adjustment process mode
1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.
2) While holding down the “VOL (–)” and “INPUT” keys at a time, plug in the AC cord of the main unit to turn on the power.
The letter “<K>” appears on the screen.

3) Next, hold down the “VOL (–)” and “CH ( V )” keys at a time.
(The “VOL (–)” and “CH ( V )” keys should be pressed and held until the display appears.)
Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode. When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.
4) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When the power was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)
CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If the settings are tampered in this mode, unrecoverable system damage may result.

Adjustment method after PWB and/or IC replacement due to repair

Special features
1. NORMAL STANDBY CAUSE
Display of a cause (code) of the last standby.
The cause of the last standby is recorded in EEPROM whenever it is possible.
Checking this code will be useful in finding a problem when you repair the troubled set.
2. EEP SAVE (Page 24/20)
Storage of EEP adjustment value.
3. EEP RECOVER (Page 20/20)
Retrieval of EEP adjustment value from storage area
MONITOR ERR CAUSE
Display of a cause (code) of Error from Monitor microcomputer.
The cause of Error is recorded in EEPROM whenever it is possible.
Checking this code will be useful in finding a problem when you repair the troubled set.
1) This displays Error code and time when the error occurred.
The latest error is displayed on “1)”.
The error that happens ahead of “1)” is displayed on “2)”.
2) The character depends on the way how to acquire Time Information.
T: Time is acquired from digital broadcasting
This doesn’t contain “Time offset” which is considered a time difference and Daylight-Saving Time, etc. ...
U: Time is acquired from analog broadcasting (teletext)
B: Accumulation time of Backlight
In the case that Time information cannot be acquired, “B” is displayed.
Example) In this example, it is shown that the error occurred 3 times.
T: Time is acquired from digital broadcasting
This doesn’t contain “Time offset” which is considered a time difference and Daylight-Saving Time, etc. ...
U: Time is acquired from analog broadcasting (teletext)
B: Accumulation time of Backlight
In the case that Time information cannot be acquired, “B” is displayed.
1) 16 T07/01/01 12:03 Error code: 16 (lamp error) Time: 07/01/01 12:03
# It is latest Error.
# Time is acquired from digital broadcasting.
# Time is UTC which doesn't have Time offset.
2) 16 U01/01/01 04:07 Error code: 16 (lamp error) Time: 07/01/01 04:07
# It is Error that happens ahead of “1)”.
# Time is acquired from analogue broadcasting.
3) 16 B00000004:11 Error code: 16 (lamp error) Accumulation time: It is displayed that 4:11 have passed after Backlight driving.
* It is Error that happens ahead of “2)”.
4) 00 0000000000000 No error (“00” shows that the error is not occurred.)
Lamp Error detection
1. Function
This LCD color TV set incorporates a Lamp error detection feature that automatically turns off the power for safety under abnormal lamp or lamp
circuit conditions. If by any chance anything is wrong with the lamp or lamp circuit or if the lamp error detection feature is activated for some reason, the following will result.
1) The power is interrupted in about 500ms after it is turned on.
(A central icon on the front of the TV flash on and off.: ON for 400ms and OFF for 1600ms.)
2) If the above phenomenon 1) occurs 5 times, it becomes impossible to turn on the power.
(A central icon keep flashing on/off.)
2. Measures
1) Set the lamp error detection to OFF
Enter the adjustment process mode
 The adjustment process mode can ignore “5 times count”, so If the above phenomenon 1) occurs 1~4 times, the lamp will go out.
If Lamp Error detection pin [4pin of PD: P9602/19pin of IC2001] is “High” by a trouble with the lamp and lamp circuit, it can boot-up by the adjustment process mode.
Please execute “Lamp Error detection off-mode”.
Unplug the AC power cord of running TV set to force off the power.
While holding down the “VOL (-)” and “CH ( UP )” keys on the set at once, touch the power supply key on the set.
After a central icon flash off, separate the fingers from key on the set.
Then, you can check the operation to see if the lamp and lamp circuit are in trouble.
If you fail boot-up, retry the procedure.
2) Resetting the lamp error count
After the lamp and lamp circuit are improved from a trouble, reset the lamp error count.
(Because the power cannot be turned on, if a lamp error is detected 5 consecutive times.)
a) Enter the adjustment process mode. Entering and exiting the adjustment process mode”.
b) Using the cursor ( UP/DOWN ) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/20.
c) With the cursor ( LEFT/RIGHT ) keys, select the [LAMP ERROR RESET] value.
Finally press the cursor (OK)., the count is reset.
Check LAMP ERROR Count on adjustment process mode Page 2/20.
Public Mode
1. Starting the Public Mode
# There are two following ways to display the PUBLIC Mode setting screen.
1) Turn off the power, and turn it on again, pressing the “CHANNEL UP” and “Volume UP” keys of the main unit at the same time.
Please separate the finger from the power supply key when boot-up is confirmed with lighting of a central icon etc.
After a while, value of Enter password appears on the screen.
a) Turn off the power, refer to “3. Method of shuts down for Power supply”.
b) While holding down the “INPUT” and “Volume (+)” keys on the set at once, touch the power supply key on the set.
Please separate the finger from the power supply key when boot-up is confirmed with lighting of a central icon etc.
After a while, value of Enter password appears on the screen.
c) Display the Pass Word input screen.
2. Exiting the Public Mode Setting screen
# There are two following ways to exit the Public Mode setting screen.
1) Turn off the power.
2) Select “Execution” in the PUBLIC_Mode to execute it.
Activate the restart under the set content.
Here, the START input SOURCE setting is excluded since this item is referred to only when the power is turned on.
3. Set value of the Public Mode
# When the shipment setting is done, a set each value in Public Mode is initialized.
(PUBLIC MODE in the process mode Setting of a flag is also initialized)
# Separately, the shipment beginnings when all except for each set value in Public Mode is initialized are provided for a process mode.
(INDUSTRY INIT (-Public))
# Only when turning on the PUBLIC MODE item, each setting is effective.
# After it decides it with EXECUTE, it AC OFF/ON it to reflect a set value.
White balance adjustment
For white balance adjustment, adjust the offset values on pages 11/20.
[Condition of the unit for inspection] : Modulated light (+16)
AV MODE: DYNAMIC
Active Backlight: OFF
OPC: OFF
Asing Time: Min, 60 minute
[Input signal condition] : HDMI 1080i 15IRE (LO), 78IRE (HI)
[Adjustment reference device] : Minolta CA-210
[Adjustment procedure]
1) Display the current adjustment status at R/G/B_GAIN (HI). (Page 11/20 of process adjustment)
The signal of 78IRE is input.
2) Read the value of the luminance meter. x=0.272, y =0.277
3) Change R_GAIN (HI)/ B_GAIN (HI) (Adjustment offset value) on page 11/20 of process adjustment so that the values of the luminance meter
approach x=0.272 and y =0.277.
(Basically, G is not changed. If adjustment fails with R and B, change G. When G is lowered, the weaker of R or B must be fixed.)
4) Display the adjustment status of the current R/G/B_GAIN (LO).
The signal of 15IRE is input.
Change R_GAIN (LO)/ B_GAIN (LO) (adjustment offset value) on page 11/20 of process adjustment so that the values of the luminance meter
approach x =0.272 and y = 0.277.
5) Both HI and LO are repeating the step from 1 to 4 until becoming an aim value.
[Adjustment reference standard value]
Adjustment spec ± 0.002 Inspection spec ± 0.004 (point LO)
Adjustment spec ± 0.001 Inspection spec ± 0.002 (point HI)
6) After completing adjustments, set EEP SAVE (Page 20/20) to ON in the process menu to save the white balance adjustment value.
