|
| If you place equipment which generates a magnetic field, such as a loudspeaker, near |
|
| |
|
| the monitor, or you change the direction of the monitor, color may lose uniformity. |
|
| |
|
| The 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 red or blue shadows appear along the edges of images, adjust the convergence |
|

|
| • If you have another monitor close to this monitor, increase the distance between them |
| EN | |
|
| to reduce the interference. |
|
| |
|
| • Try plugging the monitor into a different AC outlet, preferably on a different circuit. |
|
|
|
|
| • Try the monitor on a different computer in a different room. |

|
| |
|
| • Due to the relationship between resolution, monitor dot pitch and the pitch of some |
|
| |
|
| image patterns, certain screen backgrounds sometimes show moire. Change your |
|
| |
|
| desktop pattern. |

| Two fine horizontal lines | • These wires stabilize the vertically striped aperture grille (page 17). This aperture grille |
|
| |
| (wires) are visible | allows more light to pass through to the screen giving the Trinitron CRT more color |

| and brightness. |

•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 video board.
