NOTES:
1. Connect the remote IC PIN7 and PIN16 through a jiggle switch on the USER remote handset , this switch is defined as "screen" key; Connect the remote IC PIN8 and PIN16 through a jiggle switch on the USER remote handset , this switch is defined as "factory" key,
2. On the product line's alignment service we must use special memorizer that has been well written with respective correct version data.
3. If having no special memorizer that has been well written with data when servicing out of factory, we can use blank new EEPROM. Then the new EEPROM will be automatically totally initialized with default data after main power switch is on. Most parameters are free-alignment after initialized; only need adjust the several parameters of function set parameter and system parameter adjustment menu.
4. If no blank new EEPROM or no special memo rizer that has been well written with data, we can use memorizer that has been written with old data instead, but must be totally reinitialized; the operation is as following:
a) After TV is on, press "factory" key twin­then go to the function set menu;
b) Press 'AV/TV' key and 'P.M' key on the control board, the TV turns off automatically; this means the memory having been totally initialized. Operate repeatedly if the picture has no change;
c) Switch off and exit;
d) After initialized, adjust the several parameters of function set parameter and system parameter adjustment menu.
5. The parameters of function set parameter and system parameter adjustment menu mustn't be adjusted;
* Ensure no adjustment on the following parameter except those parameter mentioned in this manual:-
a) System parameter adjustment menu (This is coming from the NN5198/ NN5199)
AFT
VIF VCO
H VCO
VIFDET NEG
VIFDET INT
VIFDET EXT
b) The ninth digital and the tenth digital of function set parameter These parameters must be IC interior values. If the above parameters have been changed, we must partially initialize the EEPROM.
6. Two different initializing
a) Fully initialize: initialize the EEPROM's most work data and preset default value. Including: work parameter of NN5199, horizontal and vertical parameter, OPTION parameter (via. function set parameter), picture mode parameter, volume mode parameter and white balance parameter.
b) Partially initialize: only initialize work parameter of NN5199 and the ninth digital and the tenth digital of function set parameter(via. ISUD0, ISUD1,ISUD3,ISUD4,ISUD5),preset as interior values.

11. Ensure the factory mode setting are set. Set-off the factory mode function and last switch off the TV set.
12. All the “NG” sets must send for repairing and recording for reference.
13. Check the AV input and output the picture and sound must be OK.
2. RELIABILITY AGING TEST:-
1. 1st lot of production sets. Sampling 20 sets for aging 7 days continues test with colour signal in. Normal production sets must be age for 1 day.
3. MECHANICAL INSPECTION:-
1. Inspect all glue are firmly placed.
2. Check all screws are tightened, no missing and loose.
3. Check all the connectors are fully located onto the chassis base.
4. Check all the safety components are firmly located onto the chassis and no damage.
5. The TV internal side should not see any excess metal materials.
6. Check all the cable and wire are OK in-used.
7. Check the FBT and switching transformers not high mounting. The big capacitor are not slanting and high mounting.
4. HIGH POTENTIAL TESTING:-
1. Set the mega-meter is set in position.(Insulation tester)
2. Set the meter to DC500V.

6. To exit the adjustment process mode after the adjustment is done, unplug the AC power cord to force off the power. (When the power is turned off with the remote controller, once unplug the AC power cord and plug it in again. In this case, wait 10 seconds or so before plugging.)
CAUTION: Use due care in handling the information described here lest the users should know how to enter the adjustment process mode. If the settings are tampered with in this mode, unrecoverable system damage may result.
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 6 seconds after it is turned on.
(The power LED on the front of the TV set turns red from green and keeps blinking in red: ON for 250 ms and OFF for 1 sec.).
2) If the above phenomenon 1) occurs 5 times consecutively, it becomes impossible to turn on the power. (The power LED remained red).
2. Measures
1) Checking with lamp error detection OFF
Enter the adjustment process mode, referring to 1. Entering and exiting the adjustment process mode. If there is a problem with the lamp or 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 in trouble.
2) Resetting the lamp error count
After the lamp and lamp circuit are found out of trouble, reset the lamp error count. If a lamp error is detected five consecutive times, the power cannot be turned on. Using the cursor (UP/DOWN) key, move to the cursor to [LAMP ERROR RESET], Line 8 on adjustment process mode service page 2/33. With the cursor (LEFT/RIGHT) keys, select the [LAMP ERROR RESET] value. Finally press the cursor (OK) eys to reset the value to “0”.
