Vidoe Level Adjustment
Press the 6 key of the test mode to display the color bar signal for
video adjustment. The OSD (on-screen display) disappears while
the color bar signal is displayed. When you press any key, the display
returns to the menu screen.
Equipment required
1) Oscilloscope: single trace or dual trace, bandwidth of 100 MHz
or more, (input impedance of 10 Mohms or higher)
(1) Video level adjustment (DVD board)
<Purpose>
To align the video output signal level with the NTSC standard. If
not adjusted correctly, luminance of the video output signal may be
too bright or too dark.
Connection
Adjustment procedure:
1) Connect an oscilloscope to the VIDEO OUT terminal.
2) Adjust the video output signal level to 1.0 ± 0.05 Vp-p.
(2) S-terminal video level check
<Purpose>
To check the S-terminal video output signal for the correct level. If
the S-terminal video output is not correct, picture will not appear
even when the monitor TV is connected to the S-terminal cable.
Connection
Adjustment procedure:
1) Connect an oscilloscope to the S-VIDEO OUT terminal.
2) Confirm that the S-Y level is 1.0 ± 0.1 Vp-p.
3) Connect an oscilloscope to the S-VIDEO OUT (S-C) terminal.
4) Confirm that the S-C burst signal level is 286 ± 80 mVp-p.
