CAUTION: Make sure TV set in "Normal condition" before switch to Service Mode for adjustment.
1. Setting the service mode by the microprocessor.
i) 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).
ii) Press the MENU key on the remote controller to get ready to select the mode (Adjustment mode, Setting mode, Check mode and Option
mode) one by one.
iii) Press the CH DOWN / UP key on the remote controller to select the item in Adjustment mode, Setting mode or Option mode.
iv) 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.
v) In Check mode the data cannot be changed.
