[8] White Balance Adjustment
Adjustment gradation values (IN) appear on page 7/11 of process adjustment, and adjustment initial values (offset value) appear on pages 8/11 and
9/11. For white balance adjustment, adjust the offset values on pages 8/11 and 9/11.
[Condition of the unit for inspection]  Modulated light: MAX (+8)
[Adjustment reference device]  Minolta CA-210
[Adjustment]
Check that the values on page 7/11 of process adjustment are set as below. If not, change them accordingly.
1) Display the current adjustment status at point 6. (Page 8/11 of process adjustment)
The display for checking the adjustment status is toggled by pressing the “6” button on the remote control.
(Normal OSD display 
→ “6”→ display for check (OSD disappears) → “6” →normal OSD display →  •  •  •)
2) Read the value of the luminance meter.
3) Change M GAMMA R6/M GAMMA  B6 (Adjustment offset value) on page 9/11 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 and B must be fixed.)
4) If G is changed in step 3),  change the values of M GAMMA G1-M GAMMA G5 on pages 8/11 and 9/11 of process adjustment as follows. When
not changed, go to step5).
Offset value of M GAMMA G1 = (Offset value of M GAMMA G6) * (160/960)
Offset value of M GAMMA G2 = (Offset value of M GAMMA G6) * (320/960)
Offset value of M GAMMA G3 = (Offset value of M GAMMA G6) * (480/960)
Offset value of M GAMMA G4 = (Offset value of M GAMMA G6) * (640/960)
Offset value of M GAMMA G5 = (Offset value of M GAMMA G6) * (800/960)
5) Display the adjustment status of the current point 5. (Each time the “5” button on the remote control is pressed, the adjustment status check dis-
play is toggled.)
(Normal OSD display 
→ “5” → Check display (OSD disappears) → “5” → Normal OSD display → • • •)
Change M GAMMA R5/M GAMMA B5 (adjustment offset value) on page 9/11 of process adjustment so that the values of the luminance meter
approach x = 0.272 and y = 0.277.
6) Repeat step 5) for points 4, 3, 2,  and 1.

[9] QS Temperature NVM Data Confirmation
During servicing of the LCD TV set , by software upgrading or by any cleaning NVM, itÅfs mandatory select the ÅgInch SettingÅh in Service Mode,
Page 2, according to the size of the TV set.
[10] Initialization to factory settings
Caution:
When the factory settings have been made,  all user setting data,  including the channel settings,  are initialized. (The adjust-
ments done in the adjustment process mode are not initialized.) Keep this in mind when initializing these settings.
Adjustment item
Adjustment conditions
Adjustment procedure
1
Factory settings
Forcibly turn off the power
(See to below caution)
•Enter  the adjustment process mode.
•Move the cursor to [Factory Init] on page 2/11.
•Use the R/C  
key to select a region from [EURO/UK/ITALY/
FRANCE/RUSSIA]and press the [OK] key.
“EXECUTING” appears and initialization starts.
After a  while,”***OK***” appears and the setting is complete.
Note: Never turn the power off during initialization.
•The following items are initialized in the factory setting.
1. User settings
2. Channel data (e.g. broadcast frequencies)
3. Password data
After adjustments,  exit the adjustment process mode.
To exit the adjustment process mode,  unplug the AC power cord from the outlet to forcibly turn off the power.
When the power is turned off with the remoto control, unpulug the AC power cord and plug it back  in.

[11] Lamp error detection
1. Functional description
This LCD colour television has a function (lamp error detection) to be turned OFF automatically (Inverter unit) for safety when the lamp or lamp circuit
is abnormal.
If the lamp or lamp circuit is abnormal, or some other errors happen, and the lamp error detection is executed, the following occur.The Inverter circuit
stops but the rest of TV continues working. The power led is green.
2. Countermeasures
Proceed to repair the inverter unit to solve the problem that produces the lamp error.
3. Reset standby cause error list
For 26/32” this is not necessary because the lamp error detection is not operative by software.
[12] Public Mode (Hotel Mode)
1. How to Enter in the Public Mode (Hotel Mode).
Turn on the power and enter in the Adjustment Process mode (ADJ1 or Service Mode) as usual.
In the [INIT], Page 2/11 of Service, turns ON the Public Mode option.
Turn off TV by pressing Main Power switch.
While pressing “VOL+” and “P^” keys at the same time, press Main Power switch for more than 2 seconds.
After this sequence the TV will turn on showing the Public Mode setting screen as follows:
Is possible to select each item of function by pressing cursor UP/DOWN keys on the remote control or CH(
)(
) keys on the LCD TV.
The setting position of each item of functions is made by pressing cursor RIGHT/LEFT keys on the remote control or VOL(+)(-) keys on the LCD TV.
Select EXECUTE position after you set all function, and press cursor RIGHT/LEFT keys on the remote control or VOL(+)/(-) keys on the LCD TV for
confirmation.

If “FIXED” has been selected, is possible to set a fixed volume at the level that is chosen.
5. RC BUTTON [RESPOND 
↔ NO RESPOND]
If “NO RESPOND” is selected, the remote control keys are inoperative.
6. PANEL BUTTON [RESPOND 
↔ NO RESPOND]
If “NO RESPOND” has been selected, the set’s keys remain deactivated (Except POWER key).
7. MENU BUTTON [RESPOND 
↔ NO RESPOND]

TROUBLESHOOTING TABLE
[1] TROBLESHOOTING TABLE
Power unit operation check.
               
Are the power cord and harness in the unit properly connected?
NO
Connect the power cord and harness properly, and turn on the 
power.
YES
Is F701 normal?
NO
Are both ends of C704, C707 (26) and C705 (32) short-circuited 
when checking their resistance values?
YES
NO
YES
Replace F701.   
Is a voltage of BU5V applied to pin (20) of P701?
(Set the main power SW to OFF.) 
C704 
••• Check VA701, VA702 and D701.
C707 (26)/C705 (32) 
••• Check IC704 and 705.
YES
               
NO
Is a voltage of approx.
8 - 15V to pin (4) of 
IC705?
NO
Check IC705, IC708, D725 and Q724.
YES
Check short circuit of 5V line (D737, 
C752, etc.). 
Is it a symptom that the relay clatters twice as soon as the main 
power SW is set to ON and the power is not supplied?
NO
YES
Does the same symptom appear even if R858 (2.7k) is 
removed and the power is supplied again?
NO
Check IC704, D728, D762 and D736. If there are no problems, 
check the resistance value between pins (1) and (6) of P704.
When the value is low (several 
Ω - several hundred Ω), 
disconnect P704. If the value is still low, the parts of 24V line are 
defective. When the resistance value is several k
Ω, check the 
inverter unit.
YES
Check Q724, D731, D734, IC707, D751, D753, D754, 
D741, D759 and D746.

YES
YES
NO
Check peripheral circuits of D738, R828 and D735.
Check peripheral circuits of Q712, Q713, Q721, Q723 
and RY701.
There is a possibility that control by P-CON is not performed 
properly. Check whether the “PS-ON” and “PS-ON2” signals are 
sent from pins (97) and (91) of IC1710 (FPGA) of MAIN-UNIT.
