stick sensor to LCD module when you adjust.
- For manual adjustment, it is also possible by the following
sequence
1) Select RF no signal by pressing “POWER ON” key on
remote control for adjustment then operate heat run
more than 15 minutes.
(If not executed this step, the condition for W/B will be
differ. The W/B condition is Picture Mode : Standard
(MA : Optimum), Color Temp : Normal. )
more than 15 minutes.
(If not executed this step, the condition for W/B will be
differ. The W/B condition is Picture Mode : Standard
(MA : Optimum), Color Temp : Normal. )
2) Changing to the av mode by pushing the input or front av
key.
3) Display the internal pattern of the VCT-Pro IC by
pushing the IN-START.
4) Stick sensor to center of the screen and select each
