DEFLECTION CIRCUIT ADJUSTMENT
●
There are 2 modes of adjustment (initial setting value) — 50Hz mode and 60Hz mode — depending upon the kind of signals (vertical
frequency 50Hz / 60Hz).
●
When adjusted in 50Hz mode, 60Hz mode will be automatically set.
The setting (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.
