ADJUSTMENT PRECAUTIONS
This model's setting are adjusted in two dif
ferent ways: through the I
2
C bus control and in the conventional
analog manner
.
The adjustments via the I
2
C bus control include preset-only items and variable data.
CAUTION: Make sure
TV Set is in "Normal Condition" before switch to Service Mode for adjustment.
1. Setting the service mode by the microprocessor
.
1
. Short JA 137 & JA 138 for 1 second and release to switch to the service mode position, and the
microprocessor is in input mode. (Adjustment through the I2C bus control). (Use JWS Key to set as well).
2
. Press the CH DOWN / UP key on the remote controller to get ready to select the mode one by one.
3
. Press the CH DOWN / UP key on the remote controller to select the modes reversibly one by one.
4
. Using the VOLUME UP/ DOWN key on the remote controller
, the data can be modified.
5
. Short JA 137 & JA 138 for 1 second and release to switch to the normal mode (OFF) position, and the
microprocessor is in out of the service mode.
2.
Factory Presetting.
1
.Short JA 137 & JA 138 then turn "ON" the main power and release to switch to the Service Mode
position.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 8, 9, & 10.
3
. Make sure the data need modify or not (Initial data).
Note:
Once the chassis has been assembly together and ready to be POWER ON for the FIRST TIME, make sure to short JA137 & JA138 to switch to the service mode position first and then turn on the main power switch (See 2-(1) above). Precaution: If haven't done this initiation, it may possibly generate excessive Beam current.
