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
/If you do the above procedures and the monitor does not recover.
—Unplug the video cable (HD15) then press and hold the ¬ + button for 2 seconds to display the color bars. Then, turn the
monitor off and on by pressing the u power switch.
If the monitor does not recover, the monitor is out of order.
/If the u (power) and/or the POWER SAVING indicator is flashing
—Turn the monitor off and on. If the indicator is not flashing, the monitor is in the normal condition. If the indicator is still flashing, there is a potential monitor failure.
/If your computer is a Macintosh system
—Check that micro switches are properly set on the Macintosh adapter for your system. (See the adapter manual.)
Picture is scrambled
/Check your graphics board manual for the proper monitor setting on your Multiscan 20sfII.
/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
White does not look white
/Adjust the “COLOR TEMPERATURE” on the OSD. (page 7)
/If your computer is a Macintosh system, check that micro switches are properly set on the Macintosh adapter for your system. (See the adapter manual.)
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.
Edges of the image are curved
/Adjust pincushion using the “GEOMETRY” OSD. (page 6)
White lines show red or blue shades at edges
/Adjust the “CONVERGENCE” on the OSD. (page 7)
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
/If red or blue shades are found at the edge of images, adjust the “CONVERGENCE” on the OSD. (page 7)
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 produce this symptom.
Two fine horizontal lines (wires) are visible
/These wires stabilize 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.
