SAFETY CHECK-OUT
(US Model only)
After correcting the original service problem,
perform the following safety checks before releasing
the set to thecustomer:
1. Check the area of your repair for unsoldered or
poorly-soldered connections. Check the entire
boardsurfacefor solder splashes and bridges.
2. Check the interboard wiring to ensure that no
wires are "pinched" or contact high-wattage
resistors.
3, Check that all control knobs, shields, covers,
ground straps, and mounting hardware have
been replaced. Be absolutely certain that you
havereplacedall the insulators.
4. Look for unauthorized replacement parts, par-
ticularly transistors, that were installed during
a previous repair. Point them out to the cus-
tomerandrecommendtheirreplacement.
5. Lookfor parts which, though functioning, show
obvious signs of deterioration. Point them out
to the customer and recommend their replace-
ment.
6. Check the line cords for cracks and abrasion.
Recommend the replacement of any such line
cord to the customer.
7. Check the B+ and HV to see if they are at the
values specified. Make sure your instruments
areaccurate; be suspicious of your HV meter if
setsalways have low HY.
8. Check the metal trim, metallized knobs,
screws, and all other exposed metal parts
for ACleakage.
Checkleakageas described below.

LEAKAGE TEST
The AC leakage from any exposed metal part to
earth ground and from all exposed metal parts to any
exposed metal part having a return to chassis, must
not exceed 0.5mA (500 microampers). Leakage
current can be measured by any one of three
methods.
I. A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. Follow the
manufactures' instructions to use these instru-
ments.
2. A battery-operated AC milliammeter. The Data
Precision 245 digital multimeter is suitable for
thisjob.
3. Measuring the voltage drop across a resistor by
means of a VOM or battery-operated AC volt-
meter. The "limit" indication is 0.75V, so
analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of a passive VOM that
is suitable. Nearly all battery operated digital
multimeters that have a 2V AC range are
suitable. (See Fig. A)
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is guaranteed earth ground; the
cover-plate retaining screw on most AC outlet boxes is
also at earth ground. If the retaining screw is to be
used as your earth-ground, verify that it is at ground
by measuring the resistance between it and a cold-
water pipe with an ohmmeter. The reading should be
zero ohms. If a cold-water pipe is not accessible,
connect a 60-100 watts trouble light (not a neon
lamp) between the hot side of the receptacle and the
retaining screw. Try both slots, if necessary, to locate
the hot side of the line, the lamp should light at
normal brilliance if the screw is at ground potential.

SECTION 1
GENERAL
1-1. GENERAL OF PVM-1353MD
Features The operating instructions mentioned here are partial abstracts from
the Operating Instruction Manual. The page numbers of the
Operating Instruction Manual remain as in the manual.
Picture
HR (High Resolution) Trinitron picture tube
HR Trinitron tube provides a high resolution picture.
Horizontal resolution is more than 600 TV lines at the
center of the picture.
Comb filter
When NTSC video signals are received. a comb filter
activates to increase the resolution. resulting in fine picture
detail without color spill or color noise.
Beam current feedback circuit
The built-in beam current feedback circuit assures stable
white balance.
Inputs
Two color systems available
The monitor can display PAL. and NTSC signals. The
appropriate color system is selected automatically.
Analog RGB/component input connectors
Analog RGB or component (Y.R-Yand B-Y) signals from
video equipment can be input through these connectors.
Press the ROB/COMPONENT A/B select button on the
front panel and select RGB or component signals from the
on-screen menu.
Y/C input connector (S input connector)
The video signal, split into the chrominance signal (C) and
the luminance signal (Y), can be input through this
connector, eliminating the interference between the two
signals, which tends to occur in a composite video signal,
assuring video quality.
External sync input connectors
When the external RGB or component signal is input and
sync signal is set to external in the on-screen menu, the
monitor can be operated on the sync signal supplied from
an external sync generator.
Automatic termination
(only terminals with the ..1\./v-mark)
The BNC input connectors on the rear panel are terminated
at 75 ohms inside, when no cable is connected to the loop-
through output connectors. When a cable is connected to an
output connector, the 75-ohm termination is automatically
released.

Functions
On-screen menus
You can set color temperature. CHROMA SET UP. and
other settings by using the on-screen menus.
Overscan mode
The display size is enlarged by approximately 20C/cand the
center part of the screen is easier to watch.
Underscan mode
The signal normally scanned outside of the screen can be
monitored in the underscan mode.
IU:Jrl
When the monitor is in the underscan mode, the dark RGB
scanning lines may appear on the top edge of the screen.
These are caused by an internal test signal, rather than the
input signal.
Split function
The display splits into two parts (upper and lower), The
upper part of the screen monitors the signal fed through the
RGB/COMPONENT A input connectors and lower part of
the screen monitors the signal fed through the RGB/
COMPONENT B input connectors. You can compare the
two screens.
Caption vision (Closed Caption) decoder
When a signal with Caption Vision is input, the ciption is
superimposed on the screen. You can select ON or OFF and
set the caption type on the on-screen menu.
Auto/manual degaussing
Degaussing of the screen can be performed automatically
when the power is turned on, or manually by pressing the
DEGAUSS button.
Five menu languages
You can select the language used for on-screen menus from
the five languages.
Splash proof cover(s) and control panel cover
Splash proof covers that protect the ventilation holes from
splashes (of medicines, etc.) and a control panel cover that
protects the control buttons on the front panel from
undesired touching are supplied.
Quick Reference Card
The Quick Reference Card is supplied to help you
understand the menu configuration and operating method.
You can attach the supplied double-sided adhesive tape~ on
the rear of the card.
EIA standard 19-inch rack mounting
By using an MB-502B (for PV:.1-l353MDJ or SLR-103
(for PVM-1953~10) Mounting Bracket (not supplied). the
monitor can be mounted in an EIA standard 19-inch rack.
For details on mounting, see the instruction manual of the
mounting bracket kit. 3
