PowerSavingFunction
This display meets the power saving guidelines set by the International
ENERGY STAR Program. It is capable of reduced power consumption when
used with a computer equipped with Display Power Management Signaling
(DPMS). By sensing the absence of the sync signal coming from the computer,
it will reduce the power consumption as follows:

• Before disconnecting the power cord, wait at least 30 seconds after turning
off the power switch to discharge static electricity from the CRT display
surface.
• After the power has been turned on, the CRT is demagnetized for
approximately 5 seconds. This generates a strong magnetic field around the
bezel which may affect the data stored on magnetic tape or disks near the
bezel. Place such magnetic recording equipment and tapes/disks at a distance
from this unit.
The socket-outlet shall be installed near the equipment and shall be easily
accessible.

The Trinitron tube has a vertically stripedAperture Grille inside. TheAperture
Grille allows more light to pass through to the screen giving the Trinitron CRT
more color and brightness.
The damper wires are attached to the Aperture Grille to prevent vibration of the

mEnsure that no pins are bent or pushed in the HD15 connector of the cable.
mCheck that the video card in your computer is seated completely in a proper
bus slot.
mCheck that the video sync signal is within that specified for the display.
mThis display has a self-diagnostics function. To activate the function, turn off
the computer and the display. Press and hold the uswitch of the display for
about 8 seconds. If the display is operating correctly, the screen will become
white first and then the color bars will appear.
If the uindicator is flashing in orange
mCheck that the video sync signal is specified for the display.
mThere is a potential display failure. Contact Sony Technical Support.
No sound from speaker
If the ¤indicator is lit
mPress the ¤button to cancel muting.
mCheck that the audio plug is properly connected.
mAdjust the volume with .+/– buttons.
mCheck that the headphones are not connected.
mCheck that the sound board of the computer is properly connected.
mCheck that the volume control, muting, sound selector, etc. of the sound
board. (See the computer’s manual.)
Microphone mixing is not possible
mCheck that the MIC plug is properly connected.
mCheck that the sound board of the computer is properly connected.
mCheck that the microphone control, sound selector, etc. of the sound board.
(See the computer’s manual.)
Troubleshooting

GB
Howling (feed-back) is heard
mDecrease the volume with .+/– buttons, or turn down the microphone
input volume of the sound board.
Picture is scrambled
mCheck your graphics board manual for the proper display setting on the
display.
mCheck this manual and confirm that the graphic mode and the frequency at
which you are trying to operate is supported. Even within the proper range,
some video boards may have a sync pulse that is too narrow for the display to
sync correctly.
Color is not uniform
mTrip the uswitch once to activate theAuto-degauss cycle*.
Picture is flickering
mIf the refresh rate is not appropriate, the picture may flicker. Set the refresh
rate of the non-interlace mode as high as possible on the computer. For
details on how to set the refresh rate, consult the dealer of your computer or
video board.
Screen image is not centered or sized properly
mAdjust picture centering, size, or geometry (rotation/ pincushion) on the OSD
(pages 19–22).
mSome video modes do not fill the screen to the edge of the display. There is
no single answer to solve the problem. There is a tendency for this problem
to occur on higher refresh timings.
Picture is fuzzy
mAdjust the contrast and brightness on the OSD (pages 17, 18). Some brands
of SVGA boards have an excessive video output level which creates a fuzzy
picture at maximum contrast.
mThe GPE setting may not be proper for the picture. Selecting a lower GPE
number may improve the picture (page 25).
mTrip the uswitch once to activate theAuto-degauss cycle*.
Picture bounces or has wavy oscillations
mIsolate and eliminate any potential sources of electric or magnetic fields.
Common causes for this symptom are electric fans, fluorescent lighting, laser
printers, etc.
mIf you have another display close to this display, increase the distance
between them to reduce interference.
mTry plugging the display into a different AC outlet, preferably on a different
circuit.
Picture appears to be ghosting
mEliminate the use of video extension cables and/or video switch boxes if this
symptom occurs. Excessive cable length or weak connections can produce
this symptom. Continued to the next page ➔

Fine horizontal lines (wires) are visible
mThese wires stabilize the vertically stripedAperture Grille. TheAperture
Grille allows more light to pass through to the screen giving theTrinitron
CRT more color and brightness.
Wavy or elliptical (moire) pattern is visible
mDue to the relationship between resolution, display Aperture Grille pitch and
the pitch of some image patterns, certain screen backgrounds, especially gray,
sometimes show moire which looks like wavy lines. This can only be
eliminated by changing your desktop pattern.
Hum is heard right after the power is turned on
mWhen the power is turned on, theAuto-degauss cycle* is activated.While the
Auto-degauss cycle is activated, a hum may be heard for about 3 seconds.
This is not a malfunction.
* The Auto-degauss function demagnetizes the metal frame of the CRT to obtain a
neutral field for uniform color reproduction. If a second degauss cycle is needed, allow
a minimum interval of 20 minutes for the best result.
• If the problem persists, call your authorized Sony dealer from a location near
you, or call Sony Technical Support.
• Note the model name and the serial number of your display. Also note the
make and name of your computer and video board.

• HOW TO HANDLE AN ANODE-CAP
1Don’t hurt the surface of anode-caps with shartp shaped material!
2Don’t press the rubber hardly not to hurt inside of anode-caps!
A material fitting called as shatter-hook terminal is built in the
rubber.
3Don’t turn the foot of rubber over hardly!
The shatter-hook terminal will stick out or hurt the rubber.

ADJUSTMENTS
Fixing DY with wedges.
“a” and “b” must be equal, and
“c” and “d” must be almost equal.
9. Adjust vertical swing with vertical pins, and also adjust hori-
zontal swing so that horizontal keystone and vertical tilt are
optimum, then fix with four wedges.
(When fixing DY with wedges, insert wedges completely so
that the DY does not shake.)
Note:
(1) Do not paste more than 2 magnets to one corner.
(2) Paste within 80 to 100 mm from the DY on the diagonal line
of the magnet.
<How to drive in wedges>
Apply a locking agent to the
upper wedges only.
In such a case, apply agent so that
it enters both sides of wedge and
also inside the DY.
10. Check the landing of each corner, and if they do not satisfy
the specification, paste a Disk-Mg onto the funnel and ad-
just.
11. If using the magnet, be sure to demagnetize with the hand
degausser and check.
12. Remove the sensor and wobbling coil.
13. Check that the DY is not tilting, and fix the purity Mg with a
white pen.
•Landing Rough Adjustment
1. Enter the full white signal. (or the full black dots signal)
2. Set the contrast to “CONT”=MAX.
3. Make the screen monogreen.
Note: Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet (2-
pole Mg) so that a green raster positions in the center of
screen.
The 2-pole Mg adjustment must be done on the DY side (do
not use 2-pole Mg on the neck assy side).
Note: Stack 2-pole Mg on neck assy side with their sides flushed.
Adjust color Knob
to non-color Knob.
5. Moving the DY forward, adjust so that an entire screen be-
comes monogreen.
6. Adjust the tilt of DY, and fix lightly with a clamp.
Note: “TILT” shall be set at 0.
•Landing Fine Adjustment
1. Put the set inside the Helmholtz coil.
2. Input the single green signal.
(Adjust to L/D control brightness)
[L/D control brightness]
Adjust L/D after aging for 2 hours with L/D control bright-
ness

(2) Practical max brightness ......110 cd/m2∑Ik = 595 uA
[L/D control specification]
In Y axis : ± 7.5 um
At corners : ± 5.0 um
3. Demagnetize the CRT surface with the hand degausser , and
perform auto degaussing.
Note: Adjust in a non-magnetic field.
4. Attach the wobbling coil to the designated part of the CRT
neck.
5. Pull out the TLH correction piece up to the position where a
stopper is engaged.
6. Attach the sensor of the landing adjustment unit on the CRT
surface.
7. Adjust the DY position and purity, and the DY tilt.
For the purity adjustment, use 2-pole Mg on DY side.
8. Fasten DY with screw.
Note: Torque 22 ±2kg·cm (2.2 ± 0.2 Nm)
Perform auto degaussing.
