Screen image is not centered			• Press button (page 5).
or sized properly			• Adjust the size or centering (page 7).
			Some video modes do not fill the screen to the edges. This problem tends to occur with
			certain graphic boards.
Edges of the image are			• Adjust the geometry (page 8).
curved
White lines show red or blue • Adjust the convergence (page 10).
shadows at edges
Picture is fuzzy			• Adjust the contrast and brightness (page 6).
			• Degauss the monitor (page 11).
			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
			(page 10).
			• Select MOIRE ADJUST and adjust the moire cancellation effect (page 12).
Picture bounces or has wavy • Isolate and eliminate any potential sources of electric or magnetic fields. Common
oscillations			causes 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	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.
Picture is flickering			• Set the refresh rate on the computer to obtain the best possible picture by referring to
			your computer’s manual.
Picture appears to be			• Eliminate the use of video cable extensions and/or video switch boxes if this symptom
ghosting			occurs. Excessive cable length or a weak connection can produce this symptom.

pattern is visible			The moire may be modified depending on the connected computer.
			• Change your desktop pattern. Due to the relationship between resolution, monitor dot
			pitch and the pitch of some image patterns, certain screen backgrounds sometimes
			show moire.
Two fine horizontal lines			• These wires stabilize the vertically striped aperture grille (page 16). This aperture grille
(wires) are visible			allows more light to pass through to the screen giving the Trinitron CRT more color
			and brightness.
IMAGE RESTORATION			• Before using this function, the monitor must be in normal operation mode (green
function does not operate			power indicator on) for at least 30 minutes. For more information on using the IMAGE
			RESTORATION function, see “Restoring the color” on page 13.

Hum is heard right after the • When the power is turned on, the auto-degauss cycle is activated. While the auto-

power is turned ondegauss cycle is activated, a hum may be heard. The same hum is heard when the monitor is manually degaussed. This is not a malfunction.
