• IGNITION NOISE: 

Black spots or horizontal streaks may appear, picture may flutter or drift. Usually 
caused by interference from automobile ignition systems, neon lamps, electrical 
drills, and other electrical appliances. 

 

• GHOSTS: 

Ghosts are caused by the monitor signal following two paths. One is the direct path 
and the other is reflected from tall buildings, hills or some other objects. Changing 
the direction or position of the antenna may improve reception. Ghosting may also 
be caused by defects in the antenna system such as unshielded leads or connecting 
several sets to the same antenna without using multiple antenna couplers.

 

 

• SNOW: 

If your receiver is located in the fringe area of a television station where the signal is 
weak, your picture may be marred by the appearance of small dots. When the signal 
is extremely weak, it may be necessary to install a special antenna to improve the 
picture.

 

 

• RADIO FREQUENCY INTERFERENCE: 

The interference produces moving ripples or diagonal streaks, and in some cases, 
causes loss of contrast in the picture. 

• PREVENTION OF AN OBSTACLE TO RADIO RECEIVERS 

This monitor has been designed pursuant to the FCC class B Rules. This is to 
prevent a problem to Radio receivers. If this monitor causes a problem to Radio 
receivers, then take the following steps: 

- Keep the monitor away from Radio. 
- Adjust Radio antennas in order for the monitor not to receive interference. 
- The antenna cable of Radio should be kept away from the monitor. 
- Use a coaxial cable for antenna. 

You can check if this monitor influences Radio receivers by turning off all other 
equipment other than the monitor. 
If you find a problem receiving Radio when using the monitor, check the instructions 
mentioned above.

 

• The display image appears   
 scrolling diagonal.  
• Text displayed across the

 

screen  

 appears vertically

 

streaked, with   

 the characters

 

in vertical columns   

 blurred.

 

• Adjust the horizontal clock and clock phase.

 

(Adjust the horizontal clock first, the clock

 

phase next.)

 

(RGB input)

 

• Text displayed across the

 

  screen appears blurred.

 

• A fine pattern flickers when

 

  displayed on the screen.

 

• Adjust the clock phase for the clearest viewing.

 

(RGB input)

 

• Vertical stripes appear, depending on the   
 screen contents.

 

• The plasma display panel is lighting the

 

phosphors by the discharge of internal

 

radiation. Depending on the screen

 

contents, in rare cases this may cause

 

vertical 

stripes to appear because of failure

 

to light. Please note that this is not a

 

malfunction.

 

• Coarse horizontal stripes appear in FULL

   

 

display.

 

• Adjusting the clock phase will reduce the

 

horizontal stripes.

 

(RGB input)

 

• The display dims to make the picture

 

invisible 

  during special playback of a

 

VCR (FF, REW).

 

• This condition may occur when the unit is

 

connected to a VCR with component 

output,

 

such as 480i, but it is not a failure. But when

 

it occurs, switch to composite 

output.
