Power Saving Function
This display meets the power saving guidelines set by the International
E NERGY S TAR 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:
✔ CAUTION
The Power Saving function will automatically put the display into Deep Sleep mode if the
power switch is turned on without any video signal input. Once the horizontal and vertical
syncs are sensed, the display will automatically return to its Normal Operation mode.

LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground
and from all exposed metal parts to any exposed metal part hav-
ing a return to chassis, must not exceed 0.5 mA (500
microampers).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers’ instructions to
use these instruments.
2. A battery-operated AC milliammeter. The Data Precision
245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indica-
tion is 0.75 V, so analog meters must have an accurate low-
voltage scale. The Simpson 250 and Sanwa SH-63Trd are
examples of a passive VOMs that are suitable. Nearly all
battery operated digital multimeters that have a 2 V AC
range are suitable. (See Fig. A)
WARNING!!
NEVER TURN ON THE POWER IN A CONDITION IN
WHICH THE DEGAUSS COIL HAS BEEN REMOVED.

After correcting the original service problem, perform the fol-
lowing safety checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-sol-
dered connections. Check the entire board surface for 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 have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly tran-
sistors, that were installed during a previous repair. Point
them out to the customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious
signs of deterioration. Point them out to the customer and
recommend their replacement.
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 specified values.
Make sure your instruments are accurate; be suspicious of
your HV meter if sets always have low HV.
8. Check the antenna terminals, metal trim, “metallized”
knobs, screws, and all other exposed metal parts for AC
Leakage. Check leakage as described below.

Graphic Picture Enhancement (GPE)
Available GPE modes
Graphic Picture Enhancement is a function designed for your viewing
comfort.
There are four GPE modes: AUTO, MODE 1, MODE 2 and OFF.
The default setting is “AUTO.”
pAUTO mode
This mode is effective only with “IntelliLight” compatible applications.
When an image playback window with “IntelliLight” coding appears on
the screen, the display senses the exact location and size of the window
and applies a higher brightness and sharpness effect to images inside the
window, while the rest of the screen remains at standard picture quality.
For inquiries about “IntelliLight” and compatible software, check Sony’s
web site (www.ita.sel.sony.com) or call Sony Technical Support (1-888-
4SONYPC).
“IntelliLight” is a trademark of Sony Electronics Inc.
✔ Note on the AUTO mode
If one of the four corners of the “IntelliLight”window is covered or if the window goes
beyond the screen border, the GPE effect turns off.
✎ Tip
You can adjust the picture contrast or brightness of the screen outside of the “IntelliLight”
window.The“IntelliLight” window always remains clear and sharp regardless of the
adjustments made to the rest of the screen.
pMODE 1
Higher contrast is applied across the entire screen. MODE 1 is designed
to enhance still image presentations.
✔ Note on MODE 1
Whenever the screen resolution is changed, power saving activated, or power turned off,
MODE 1 is cancelled and GPE returns to theAUTO mode.

No picture
If the Uindicator is not lit
mCheck that the power cord is properly connected.
mCheck that the Uswitch is in the “on” position.
If the “NO INPUT SIGNAL” message appears on the screen, or if the U
indicator is either orange or alternating between green and orange
mTry pressing any key on the computer keyboard.
mCheck that your computer power switch is in the “on” position.
mCheck that the video signal cable is properly connected and all plugs
are firmly seated in their sockets.
mEnsure that no pins are bent or pushed in the HD15 video input
connector.
If the “OUT OF SCAN RANGE” message appears on the screen
mCheck that the video frequency is within that specified for the display.
Horizontal: 30 – 70 kHz
Vertical: 50 – 120 Hz
Refer to your computer’s instruction manual to adjust the video
frequency range.
mIf you are using a video signal cable adapter, check that it is the correct

(See the computer’s manual.)
Troubleshooting
37
Howling (feedback) is heard
mDecrease the volume with .+/– buttons, or turn down the
microphone input volume of the sound board.
Picture is scrambled
mCheck your computer manual for the proper display setting.
mCheck this manual and confirm that the graphic mode and the
frequency you are trying to operate is supported. Even if the
frequency is 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
mDegauss the display (page 27).
If you place equipment which generates a magnetic field, such as a
speaker, near the display, or you change the direction of the display,
color may lose uniformity. The 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.
Screen image is not centered or sized properly
mAdjust the size or centering (pages 22, 23).
mSome video modes do not fill the screen to the edge. This problem
tends to occur with certain video boards.
Edges of the image are curved
mAdjust the geometry (page 24).
Picture is fuzzy
mAdjust the contrast and brightness (page 21). Some brands of video
boards have an excessive video output level which creates a fuzzy
picture at maximum contrast.
mDegauss the display (page 27).
If you place equipment which generates a magnetic field, such as a
speaker, near the display, or you change the direction of the display,
color may lose uniformity. The 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.
mIf moiré is cancelled, the picture may become fuzzy. Decrease the

mSet the refresh rate on the computer to obtain the best possible picture
by referring to your computer’s manual.
mIf the GPE mode is set to AUTO, change it to OFF (page 32).
Picture appears to be ghosting
mEliminate the use of video extensions and/or video switch boxes if
this symptom occurs. Excessive cable length or weak connections can
produce this symptom.
mIf the GPE mode is set to AUTO, change it to OFF (page 32).
mIf the GPE mode is set to MODE 2, the picture may appear to be
ghosting. Set to another GPE mode (page 32).
Wavy or elliptical (moiré) pattern is visible
mCancel the moiré (page 26).
The moiré may be modified depending on the connected computer.
mDue to the relationship between resolution, display dot pitch and the
pitch of some image patterns, certain screen backgrounds sometimes
show moiré. Change your desktop pattern.
IntelliLight does not work
mCheck that all four corners of the “IntelliLight” window are clearly
displayed and are not covered by another window.
mCheck that the GPE mode is set to AUTO (page 32).
mLeave the display’s power “on” and reboot your computer.
mIntelliLight does not work correctly with an interlaced video mode.
Check the vertical refresh rate in the Properties window of Windows
95/98 and select a non-interlaced mode.
Tiny color bars appear in the corners of the IntelliLight window
mSet the GPE mode to AUTO (page 32).
mCheck that all four corners of the “IntelliLight” window are clearly
displayed and are not covered by another window.
Troubleshooting
39
A fine horizontal line (wire) is visible
mThis wire stabilizes the vertically striped Aperture Grille (page 16).
This Aperture Grille allows more light to pass through to the screen
giving the Trinitron CRT more color and brightness.
Hum is heard right after the power is turned on
mWhen the power is turned on, the Auto-degauss cycle is activated.
While the Auto-degauss cycle is activated, a hum may be heard. The
same hum is heard when the display is manually degaussed. This is
not a malfunction.
• If the problem persists, call your authorized Sony dealer from a
location near you, or call Sony Technical Support at 1-888-4SONYPC
(1-888-476-6972).
