Access the SBU as explained in
“Preparation” above.
Set the oscilloscope scale to 0.2
V/unit (vertical) and 0.5 ms/unit
(horizontal).
tight the fluorescent lamps.
Place the scan line test chart [A] on
the exposure glass as shown.
Connect the oscilloscope to the test
lead as follows: Channel 1 to
XVIDEO, channel 2 to SH, ground to
GND.
Set the oscilloscope scales as fol-
lows: Vertical - CH1 0.2 V/unit, CH2
2 V/unit; Horizontal - 2 µs/unit.
Gently tap the SBU until the
waveform is as shown on the right.
The peak of XVIDEO must be within
4 bits of the peak of SH.
Reset the oscilloscope to the
original settings and repeat proce-
dure 6 (scan line) on the previous
page. It may be necessary to
recheck procedures 6 and 7 until
the scan line is perfectly positioned.
Tighten the SBU securing screws.
