SECTION 1

GENERAL

The operating instructions mentioned here are partial abstracts from
the Operating Instruction Manual. The page numbers of the
Operating Instruction Manual remein as in the manual.

1-1. GENERAL OF PVM-1450QM

Features

Fine Pitch Trinitron picture tube

Fine Pitch Trinitron tube provides a high resolution picture.
Horizontal resolution is more than 450 TV lines at the center

of the picture.

Four color systems available

The monitor can display PAL, SECAM, NTSC and
NTSCH3* signals. The appropriate color system is selected

automatically.

* A signal of NTSCw is used for playing back NTSC

recorded video cassettes with a video tape recorder/
player especially designed for use with this system.

Analog RGB input connectors

Analog RGB signals from video equipment can be input
through these connectors.

Y/C input connectors

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.

Beam current feedback circuit

The built-in beam current feedback circuit assures stable
white balance.

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.

Automatic termination

(connector with 1\/v-mark only)

The input connector is 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-ohms termination is automatically
released.

Blue only mode

In the blue only mode, an apparent monochrome display is
obtained with all three cathodes driven with a blue signal.
This facilitates color saturation and phase adjustments and
observation of VCR noise.

Auto/manual degaussing

Degaussing of the screen can be performed automatically
when the power is turned on, or manually by pressing the
DEGAUSS button.

On-screen menus

You can set CHROMA SET UP and other settings by using
the on-screen menus.

Five menu languages

You can select the menu language from among the five
languages on the menu.

EIA standard 19-inch rack mounting

By using an MB-502B 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.

I. Preparations

I) To reduce the influence of geomagnetism, face the set's CRT

screen east or west.

2) Loosen the deflection yoke fixture and lower the deflection
yoke to the rear.

3) Switch on the Power switch and degauss with the degausser.

4) Adjust the deflection yoke tilt.

2. Adjustment

I) CONT······ MIN

BRT ......... Position providing good vision

2) The rough adjustments of the white balance, G2, and
convergence must be completed already.

3) Set green-only.

4) Adjust the purity knob so that the green comes to the center

of the screen. Make the red and blue about even. Fig. I

5) Switch to blue only, red only, and green only and verify each.
Fig. !, 2, and 3

6) Bring the deflection yoke gradually forward and adjust the
deflection yoke so that the R and B at both sides of the screen

become green. Fig. 2-" 3

7) If the deflection yoke comes too far forward, you will see the

pattern shown in Figure 4. If that happens, lower the
deflection yoke to the rear. Fig. 4 --;. 3

8) Switch the single color switch to B and verify the single

color. Fig. 6

9) Switch the single color switch to R and verify the single

color. Fig. 9

10) When one of the colors does not become the single color
correctly, check by repeating Items 7 and 8 based on the
single color not coming into adjustment.

If you can not obtain landing in the corners, paste on

magnets.

11) Switch to an all-white signal and check the uniformity.

12) When the deflection yoke position is determined, fasten it

with the fixture.

2. Align the horizontal R, G, and B dots at the center of the

screen with the H-STAT VR. (*I)

*I: If the H-CENTER adjustment was after the H-STAT

adjustment, re-adjust the H-ST AT.
(The H-CENT VR changes the H-STAT too.)

3. Align the R, G, and B at the center of the screen with the

V-STAT magnets. (*2)

*2 : After the V -ST AT adjustment, paint on the knobs to

lock them.

Good example

V-ST AT magnet knobs
While keeping the angles for A
and B equal (!=I'), align the
vertical convergence.

y

Bad example

If the A and B knobs are not
symmetrical (I ,;cc]'), this has
bad effects. The focus may
deteriorate and beam striking
may occur.

4. For HMC, use the 6-pole magnet to adjust the R and B dots to

be symmetrical left and right about the G dot. (*I)
