DEFLECTION CIRCUIT ADJUSTMENT
There are 2 modes of the adjustment ( 1 ) 100Hz mode (
①
FULL
②
PANORAMIC,
③
16:9 ZOOM SUBTITLE ), ( 2 ) 120Hz mode ( each
aspect mode )
･･････
depending upon the kind of signals ( vertical frequency 100Hz / 120Hz ).
"
When the 100Hz FULL mode has been established, the setting of the other modes will be done automatically.
"
However, if the picture quality has not been optimized, adjust each mode again, respectively.
"
The adjustment using the remote control unit is made on the basis of the initial setting values.
"
The setting values which adjust the screen to the optimum condition can be different from the initial setting values.
"
Regular and Zoom switching is conducted not by the Deflection circuit, but by the 100 Hz PWB. Therefore, the deflection
system cannot be adjusted in these modes.
