Electrical Adjustment; Power Supply Check; Zssr107G Board: Us, Cnd Zssr107H Board: Aep, Uk, Kr - Sony DVP-NS999ES Service Manual

In making adjustment, refer to 7-6. Adjustment
Related Parts Arrangement.
Note: During diagnostic check, the characters and color bars can
be seen only with the NTSC monitor. Therefore, for diag-
nostic check, use the monitor that supports both NTSC and
PAL modes.
Use the reference disc for PAL for check, and use the refer-
ence disc for NTSC for adjustment.
This section describes procedures and instructions necessary for
adjusting electrical circuits in this set.
Instruments required:
1) Color monitor TV
2) Oscilloscope 1 or 2 phenomena, band width over 100 MHz,
with delay mode
3) Frequency counter (over 8 digits)
4) Digital voltmeter
5) Standard commander (RMT-D150A/D150P)
6) DVD reference disc
HLX-501 (J-6090-071-A) (dual layer) (NTSC)
HLX-503 (J-6090-069-A) (single layer) (NTSC)
HLX-504 (J-6090-088-A) (single layer) (NTSC)
HLX-505 (J-6090-089-A) (dual layer) (NTSC)
HLX-506 (J-6090-077-A) (single layer) (PAL)
HLX-507 (J-6090-078-A)(dual layer) (PAL)
7) SACD reference disc

Checking method:
1) Confirm that each voltage satisfies the specification.
* However, do not measure, it in VIDEO OFF mode.
Since power of the VIDEO board (VP-58, EV-15) is shut off in
the VIDEO OFF mode, load is reduced and voltage is changed.
Especially SW + 8V.
! Caution
Never touch the heat sink that is the primary part. It is feared that
you may get an electric shock.
