The adjustment values are set to the optimum conditions at the factory before shipping.  If a value should
become improper or an adjustment is required due to part replacement, make an adjustment according to the
following procedure.

Caution: When replacing the following units, make sure to prepare the new units loaded with updated
software.

(1) Unplug the AC cord with the monitor power SW "ON".
(2) While holding down the "VOL + " and "V CH" keys at a time, plug in the monitor AC cord. The unit starts

up in the "monitor process mode".
Page 1 of the "Monitor adjustment mode" appears.
(The same displays appear on the left and right sides of the screen.)
* To exit the adjustment process mode, turn off the power.

4. Adjustment Procedure
4-1. VLS BIAS (15V) voltage adjustment

Go to "VLS BIAS" with the cursor (UP/DOWN) keys and select the value with the cursor (LEFT/RIGHT)
keys.
Connect a digital voltage meter to TP4827 (TL4843) on the LCD_CONT_TOP PWB and adjust the value
with the cursor (UP/DOWN) keys to 15.00V±0.05V.

4-2. GRAY LEVEL (14.2V) voltage adjustment

Go to "GRAY LEVEL" with the cursor (UP/DOWN) keys and select the value with the cursor (LEFT/
RIGHT) keys.
Connect a digital voltage meter to TP4501 (TL4501) on the LCD_CONT_TOP PWB and adjust a value
with the cursor (UP/DOWN) keys to 14.20V±0.05V.
Make sure to adjust the value accurately as this power supply voltage will be used as a reference voltage
for the gradation voltage.

4-3. COM BIAS adjustment

Shift to the [COM BIAS] item with the cursor UP/DOWN key and select a numeric value with the cursor
RIGHT/LEFT key.
Changing the numeric value with the cursor UP/DOWN key will make appear the test pattern.  Make an
adjustment so that the flicker near the center of the screen is minimized.

4-4. Background adjustment
(1)

Connect the AVC center and monitor for the background adjustment.

(2)

Display the adjustment confirmation screen (gray scale).

(3)

Go to "PATTERN" with the cursor (UP/DOWN) keys and press "ENTER".
Go to "PATTERN PAGE2" with the cursor (DOWN) key.

(4)

Adjust ADJ to 6 and press "ENTER".

(5)

Set the 6th point to the designated gradation and adjust RGB to obtain the standard value for the 6th
point.

(6)

Set the 1st point to the designated gradation and calculate the G set value of the 1st point using the
following formula: G initial value of the 1st point x (G adjustment value of the 6th point/928) (rounding off
fractions). Then adjust RB to obtain the standard value of the 1st point.

(7)

Set the 2nd point to the designated gradation and calculate the G set value of the 2nd point using the
following formula: G initial value of the 2nd point x (G adjustment value of the 6th point/928) (rounding off
fractions). Then adjust RB to obtain the standard value of the 2nd point.

(8)

Set the 3rd point to the designated gradation and calculate the G set value of the 3rd point using the
following formula: G initial value of the 3rd point x (G adjustment value of the 6th point/928) (rounding off
fractions). Then adjust RB to obtain the standard value of the 3rd point.

(9)

Set the 4th point to the designated gradation and calculate the G set value of the 4th point using the
following formula: G initial value of the 4th point x (G adjustment value of the 6th point/928) (rounding off
fractions). Then adjust RB to obtain the standard value of the 4th point.

(10) Set the 5th point to the designated gradation and calculate the G set value of the 5th point using the

following formula: G initial value of the 5th point x (G adjustment value of the 6th point/928) (rounding off
fractions). Then adjust RB to obtain the standard value of the 5th point.

(11) Adjust CALC to 1 and calculate. Confirm that the adjustment has been made correctly to exit.

[North America]
Standard value 1: x=0.295, y=0.305 [Minolta CA-110] (216 gradations)
Standard value 2: x=0.295, y=0.305 [Minolta CA-110] (352 gradations)
Standard value 3: x=0.295, y=0.305 [Minolta CA-110] (528 gradations)
Standard value 4: x=0.295, y=0.305 [Minolta CA-110] (656 gradations)
Standard value 5: x=0.295, y=0.305 [Minolta CA-110] (800 gradations)
Standard value 6: x=0.291, y=0.300 [Minolta CA-110] (928 gradations)

8.Lamp error detection
8-1.Feature description

This liquid-crystal colour TV incorporates a lamp error detection feature (lamp error detection) that automatically
turns OFF the power for safety under abnormal lamp or lamp circuit conditions.
If anything is wrong with the lamp or lamp circuit or when the lamp error detection feature is activated for some
reason, the following will result.

1 The power of TV main body is turned OFF about six seconds after it is turned ON.  (The power LED on

the front of the TV turns red from green and keeps blinking in red (ON for 250ms and OFF for 1sec).)

2 If 1 occurs five times consecutively, it becomes impossible to turn ON the power.  (The power LED

keeps blinking in red (ON for 250ms and OFF for 1sec).)

8-2.Measures

1).Checking with lamp error detection OFF

While the “MAIN POWER” switch is off, hold down the “P(Ù)” and “       (+)” keys and then turn the “MAIN
POWER” on. The display will run in the “Display process mode” (“<K>” will appear.).

      If there is a problem with a lamp or a lamp circuit, the lamp will go out. (The power LED is green.)
      Then, you can check the operation to see if the lamp and lamp circuit are abnormal.

2).Resetting the lamp error count

After you have finished checking whether the lamp and lamp circuit are abnormal, reset the lamp error
count. If a lamp error is detected five consecutive times, the power cannot be turned on.

      Therefore, move to the “L ERR RESET” line, the fourth line on the first page of the“Display adjustment
      mode”, using the “Cursor '/"” key. Then, reset the “L ERR RESET” value using the “Cursor Û / û” key.
      In this case, press the “Cursor '/"” key to reset it to "0".

Then perform operation checking and check that the lamp error detection feature is not activated.
