Check 11: Is the video circuit OK?
<Outline> Composite signal and component signal are output from DVD-LSI (IC1501), and are output from the
HOST I/F (CN1901) via a buffer circuit.

Fig 11.1: Video circuit
<Checking method> Playback DVD-REF-A1 TITLE2 CHAPTER5 (WHITE 100%), and monitor COMPO signal with
an oscilloscope with GNDV1 (stylus) being the reference. Set the trigger mode to “TV trigger” and
the trigger line to “150 line”.

<Video level readjustment method>
In case the video composite output is outside of the specification value, readjust the level according to the method
described below.(Note : Units are exchanged, the video output is not adjusted. )
Turn the volume (VR1671) to adjust the video level within the range of 1.0 ± 0.02 Vpp.
The adjustment specification is 1.0 ± 0.02 Vpp.
Adjust this level within the
range of 1.0 ± 0.02 Vpp.
