Note 1: Take note that GND H differs from the GND potential in
unit.
Note 2: Sustain emission
The sustain waveform must be adjusted using the sub field
with sustain emission. As the scanned portion becomes the
waveform shown in Fig. 8 in the sub field with sustain
emission when 100% white signal is input, find and adjust
this portion. Find it by differentiating it from the scanned
portion of sub fields without sustain emission which has a
distorted waveform as shown in Fig. 9.

Note 4: Position where drive voltage label is pasted
Notes:
÷
The ANALOG VIDEO ASSY (Procedure 1), and CONTROL
ASSY (Procedure 2) (Procedure 3) adjustments need not be
performed again in this unit if these ASSYs have been replaced.
÷
Other adjusting points which need not be adjusted again in this
unit when other ASSYs are replaced are as follows.
MAIN POWER ASSY
VR3501 (STB+5V)
VR3201 (Vcc+5V)
VR3101 (+B 215V)
VR3801 (VSUS UVP)
SUB POWER ASSY
VR1601 (VCSP 40V)
÷
If adjusted VRs of the above MAIN POWER ASSY and SUB
POWER ASSY are rotated accidentally, adjust to the following
values.
MAIN POWER ASSY
VR3501 (STB+5V):
Adjust the DC voltage value between
TP3501 (STB+5V) and TP3503 (STB.
GND) to +5V±0.1V.
VR3201 (Vcc+5V):
Adjust the DC voltage value between
TP3201 (Vcc+5V) and TP3202 (D.
GND) to +5.05V±0.1V.
VR3101 (+B 215V): Adjust the DC voltage value between
TP3101 (+B) and TP3102 (P.GND) to
+215V±0.5V.
VR3801 (Vsus UVP): Adjust the DC voltage value between
the R3860 lead (Pin 6 of IC3805) and
R3863 lead (+ lead of C3814) to
0±10mV.
SUB POWER ASSY
VR1601 (VCSP 40V): Check the drive voltage label value,
and adjust the DC voltage value between
TP1603 (VCSP) and TP1604 (CSP.
GND) becomes this value.
Note: Take note that the CSP.GND or GND_H differs from the
GND potential of this unit.
Never short between CSP. GND and other GND or
GND_H and other GND.
Note here
If distorted here, it means that
the address is selected and
there is no sustain emission.
