Troubleshooting Symptom Sides of the image are curved White lines show red or blue shades at edges Picture is fuzzy Picture bounces or has wavy oscillations Picture appears to be ghosting. Two fine horizontal lines (wires) are visible Wavy or elliptical (moire) pattern is visible. Check these items • Adjust the "Pincushion" control in "Geometry" adjustment mode (page 9). • Adjust the "Convergence" controls (page 9). • Adjust the "Contrast" and "Brightness" controls (page 8). We have come across several brands of SVGA boards that have excessive video output level -which creates fuzzy picture at max contrast. • Trip the power switch once to activate Auto-degauss cycle. This function demagnetizes the metal frame of the CRT to obtain 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 red or blue shades are found at the edge of images, adjust the "Convergence" controls (page 9). • 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 set 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. • Eliminate the use of video cable extension cable and/or video switch boxes if this symptom occurs. Excessive cable length or weak connections can produce this symptom. • 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. • 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. • 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.
