CPD-100ES - 6 - Entering New Timings When using a video mode that is not one of the factory preset modes, some fine tuning may be required to optimize the display to your preferences. Simply adjust the monitor according to the preceding adjustment instructions. The adjustments will be stored automatically and recalled whenever that mode is used. A total of 8 user-defined modes can be stored in memory. If the 9th mode is entered, it will replace the first. Power Saving Function This monitor meets the power saving guidelines set by the International ENERGY STAR Program as well as the more stringent TCO92 803299 (NUTEK) guidelines. 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 monitor into Active-off state if the power switch is turned on without any video signal input. Once the horizontal and vertical syncs are sensed, the monitor will automatically return to its Normal operation state. State Power consumption 1 Normal operation Stand-by 2 (1st step of power saving) Suspend 3 (2nd step of power saving) Active-off 4 (3rd step of power saving) 5 Power-off 110 W 15 W 15 W 8 W 0 W Required resumption time -- approx. 3 sec. approx. 3 sec. approx. 10 sec. -- u POWER indicator green on Orange and green flashes alternately Orange and green flashes alternately Orange on off Plug and Play This monitor complies with DDCTM1 and DDC2B, which are the Display Data Channel (DDC) standards of VESA. When a DDC1 host system is connected, the monitor synchronizes with the V. CLK in accordance with the VESA standards and outputs the EDID (Extended Display Identification Data) to the data line. When a DDC2B host system is connected, the monitor automatically switches to the DDC2B communication. DDCTM is a trademark of the Video Electronics Standard Association. Use of the Tilt-Swivel With the tilt-swivel, this unit can be adjusted to be viewed at your desired angle within 180˚ horizontally and 20˚ vertically. To turn the unit vertically and horizontally, hold it at its bottom with both hands. 15° 90° 90° 5° Damper Wire Using a white background, very thin horizontal stripes on the screen are visible as shown on the illustration. These stripes are damper wires. These wires are attached to the aperture grille inside the Trinitron tube and are there to dampen vibrations of the aperture grille in order to prevent them from influencing the picture quality.

No picture / If the u POWER indicator is not lit. - Check that the power cord is properly connected. - Check that the u POWER switch is in the "ON" position. / If the u POWER indicator is flashing in green and orange alternately. - 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 Macintosh system, check that a proper HD15 - D15 adapter is provided to work correctly with your Macintosh. - The monitor has a self-diagnose function. After disconnecting the video signal cable from the computer, turn on the u POWER switch of the monitor. Press and hold the "+" side of the > button for 2 seconds, then color bars will appear. The monitor is operating normally if the red, green, and blue color bars appear. Contact the maker of the computer to which the monitor is connected. / If the u POWER indicator is 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. Picture is scrambled / Check your graphics board manual for the proper monitor setting on your Multiscan 100ES/ 200ES. / 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 / If the monitor is close to any potential sources of magnetic fields such as a speaker, or you turn the monitor while the u POWER switch is in the "ON" position, color may not be uniform. Trip the u POWER switch once to activate the Autodegauss cycle*. Picture is flickering / If 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 detailes on how to set the refresh rate, consult the dealer of your computer or 10 video board. Screen image is not centered or sized properly / Adjust the "CENTER," "SIZE," or "GEOMETRY" on the OSD (pages 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 u 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 different 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 produce this symptom. A fine horizontal line (wire) is visible / This wire stabilizes the vertically striped Aperture Grille (page 8). 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 AG 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. Just after turning the monitor on, a "boon" noise is heard / Just after turning the monitor on, a noise may be heard for about 3 seconds. This noise is not failure, it is caused by the Autodegauss cycle∗. ∗ 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.
