ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two different ways: through the I2C bus control and in
the conventional analog manner. The adjustments via the I2C bus control include preset-only
items and variable data.
CAUTION : MAKE SURE TV SET IN "NORMAL CONDITION" BEFORE SWITCH TO SERVICE MODE
1. Setting the service mode by the microprocessor.
(1) Press SERVICE key on the remote controller to set the TV set to SERVICE mode position,
and the microprocessor is in input mode. (Adjustment through the I2C bus control).
Service Mode also can be reached by by connecting MCU Pin 5 to ground.
(2) Press the MENU key on the remote controller to get ready to select the mode
(Adjustment mode, Setting mode, Check mode, Option mode and NVM Edit mode ) one by one.
(3) Press the CH DOWN / UP key on the remote controller to select the item in Adjustment
mode, Setting mode, Option mode or NVM Edit mode.
(4) Using the VOLUME UP/ DOWN key on the remote controller, the data can be modified.
Please wait approximately 200 msec for data storage in EEPROM before select to
another mode.
(5) In Check mode the data cannot be changed.
(6) Press the SERVICE key again, it will switch to the NORMAL mode position, and the
microprocessor is out of the SERVICE mode.
2. Factory Presetting.
(1) During POWER OFF (AC OFF), switch on service key (by connecting MCU Pin 5 to ground )
after raster appeared on the screen. Initial values are automatically preset, only when
then follow by AC ON. Initial values are automatically preset only when a new EEPROM is used.
(Judge with the first 4 bytes ).
(2) The initial data are preset as listed in page 6~10.
(3) Make sure the data need modification or not (Initial data).
Precaution: If haven't done this initialization, it may possibly generate excessive Beam current.
