Color is not uniform

• Degauss the monitor (page 15).

 

 

 

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.

 

 

 

• Adjust the landing (pages 13 – 14).

 

 

 

 

 

 

You cannot adjust the monitor

White does not look white

• Adjust the color temperature (pages 12 – 13).

 

 

 

• Check that the 5 BNCs are connected in the correct order (from left to right: Red–Green–

 

 

 

Blue–HD–VD) (page 6).

 

 

 

 

 

 

Screen image is not centered or

• Adjust the size or centering (page 10).

 

 

 

• Some video modes do not fill the screen to the edges. This problem tends to occur with

 

 

 

certain video boards.

 

 

 

 

 

 

Edges of the image are curved

White lines show red or blue

• If red or blue shadows appear along the edges of images, adjust the convergence

 

 

 

 

(pages 13 – 14).

 

 

 

 

• If the moire is cancelled, the picture may become fuzzy. Decrease the moire cancellation

 

 

 

 

effect (pages 13 – 14).

 

 

 

 

 

 

 

 

Picture bounces or has wavy

• Isolate and eliminate any potential sources of electric or magnetic fields. Common causes

 

 

oscillations

for this symptom are electric fans, fluorescent lighting or laser printers.

 

 

 

• 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 different computer in a different room.

 

 

 

 

 

 

Picture is flickering

• Set the refresh rate on the computer to obtain the best possible picture by referring to the

 

 

 

computer’s manual.

 

 

 

 

 

 

Picture appears to be ghosting

• Eliminate the use of video cable extensions and/or video switch boxes if this symptom

 

 

 

occurs. Excessive cable length or a weak connection can produce this symptom.

 

 

 

 

 

 

Wavy or elliptical (moire)

• Cancel the moire (pages 13 – 14).

 

 

pattern is visible

The moire may be modified depending on the connected computer.

 

 

 

• 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 19). This aperture grille

allows more light to pass through to the screen giving the Trinitron CRT more color and

 

 

 

brightness.

 

 

 

 

 

 

Hum is heard right after the

• When the power is turned on, the auto-degauss cycle is activated. While the auto-degauss

 

 

power is turned on

cycle is activated (3 seconds), a hum may be heard. The same hum is heard when the

 

 

 

monitor is manually degaussed. This is not a malfunction.
