4.7.6 DEFLECTION CIRCUIT ADJUSTMENTS

•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.

•When performing deflection circuit adjustment, adjusts PAL signal (fv: 50 Hz) in 4:3 mode and 16:9 mode respectively, and adjust

the NTSC signal (fv: 60 Hz) similarly.

Note:

Proceed to the following adjustment after having completed the adjustments of SUB BRIGHT and SUB PICTURE.
