2.9 NTSC system horizontal and vertical adjustment
a. Receive NTSC system cross hatch pattern. Adjust same as PAL system.
2.10Warm up mode
a. Switch on power switch and Press 'factory' key one time; switch off power switch
and switch on power switch again, at this time there is no signal white raster and TV
won't switch off automatically. TV receiver can be sent to warm up line.
b. Before exit warm up line, press 'factory' key three times continue, at this time exit
warm up mode, there is no signal and the LOGO ‘AKIRA’ pattern will appear.
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 memorizer 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 twin then 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
ad justed;
* 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.
