Symptom Check ttiese Herns
No picture
If neither the (!) (power)
indicator nor the POWER
SAVING indicator is lit
• Check that the power cord is properly connected.
• Check that the power switch is in the *ON* position.
If the POWER SAVING
indicator is lit
• Check that your computer power switch is in the X)N* position.
• Check that the video cable is properly connected.
• Ensure that no pins are bent or pushed in the HD15 connector of the cable.
• Check that the video card is seated completely in a proper bus slot. There may be a
particular bus slot specified for your video board among the 8,16, and VL-Bus slots.
• Check that the video sync signal is within that specified for the monitor.
• If using a Mac system, check that a proper HD15-D1S adapter is provided to work correctly
with your Mac.
If the (!) (power) and the
POWER SAVING indicators
are both flashing
• There is a potential monitor failure. Contact your dealer.
Picture is scrambled • Check your graphics board manual for the proper monitor setting on your MuKiscan 15sV
17sf.
• Check this manual and confirm that the graphic mode and the frequency at which you are
trying to operate is supported. Even wiHiin the proper range some video boards may have
a sync pulse that is too narrow for the monitor to sync correctiy.
Color is not uniform • Trip the power switch once to activate the Auto-degauss cycle*.
Screen image is not
centered or sized properly
• Adjust “Centering", “Size", “Raster Rotation" or “Pincushion" control (pages 5 and 6).
• Some video modes do not fill the screen to the edge of the monitor. There is no single
answer to solve the problem. There is a tendency to have this problem on higher refresh
timings and Macintosh video timings.
Picture is fuzzy • Adjust the “ContrasT and “Brightness" controls (page 5). We have come across several
brands of SVGA boards that have an excessive video output level which creates a fuzzy
picture at max contrast.
• Trip the power switch once to activate the Auto-degauss cycle*.
Picture bounces or has
wavy oscillations
• Isolate euid eliminate any potential sources of electric or magnetic fields. Common causes
for this symptom are electric fans, fluorescent lighting, laser printers, and so on.
• If you have another monitor cbse to this monitor, increase the distance between them to
reduce the interference.
• Try plugging the monitor into a different AC outlet, preferably on a different circuit.
• Try the monitor on a completely different computer in a diffemt room.
Picture eippears to be
ghosting
• Eliminate the use of video cable extension cables and/or video switch boxes if this
symptom occurs. Excessive cable length or weak connections can produce this symptom.
A fine horizontal line (wire)
is visible
• This wire stabilizes the vertically striped /Vperture Grille. This Aperture Grille allows more
light to pass through to the screen giving the Trinitron CRT more color and brightness.
Wavy or elliptical (moire)
pattern is visible
• Due to the relationship between resolution, monitor dot pitch euid the pitch of some image
patterns, certain screen backgrounds, especially gray, sometimes show moire. This can
only be eliminated by changing your desktop pattern.
* The Auto-degauss function demagnetizes the metal friune 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 your question concerns the features, specifications or compatibility of the monitor, contact Sony Technical Support. If the
monitor appears to have malfunctioned, contact your nearest Sony Service Center.
Note the model name and the serial number of your monitor. Also note the make and name of your computer and video
board.
