Troubleshooting

This section may help you isolate a problem and as a result, eliminate the need to contact technical support, allowing continued productivity.

No picture

/ If neither the u (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 “ON” position.

— The monitor will recover when you press any key on the keyboard of the computer.

— 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.

— Check that the video sync signal is within that specified for the monitor.

— If using a Mac system, check that a proper

HD15-D15 adaptor is provided to work correctly with your Mac.

/ If the u (power) and the POWER SAVING indicators are both flashing

— There is a potential monitor failure.

Contact your dealer.

If the message of “OUT OF SCAN RANGE” appears on the screen

/

Check that the video sync signal is specified for the monitor.

.

/ Check 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 monitor to sync correctly.

Color is not uniform

/ Trip the power switch once to activate the

Auto-degauss cycle*.

Screen image is not centered or sized properly

/ Adjust the “CENTER”, “SIZE” or

“GEOMETRY” on the OSD (page 5, 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” on the OSD (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 and 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 close 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 differnt room.

Picture appears 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 procude this symptom.

A fine horizontal line (wire) is visible

/ This wire stabilizes the vertically striped

Aperture 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 and 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 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 your monitor.

•

Note the model name and the serial number of your monitor. Also note the make and name of your computer and video board.
