There may not be a solution to the following problems, although adjusting the antenna or taking measures against interfering equipment may improve the situation somewhat.
The screen appears snowy and noise is heard. (Snow)
Is the antenna connected properly?
Has the antenna cable been cut or loosened?
Has the antenna orientation been changed or is the antenna broken?
The image is displayed two or three times on the monitor. (Ghosting)
This may be caused by mountains or buildings. Also, if the broadcast antenna is located nearby, the TV transmission the monitor receives directly from it may affect the picture.
Spots are displayed and noise is heard. (Interference)
This may be caused by interfering radio waves generated by dryers, automobiles, motorcycles or fluorescent lights.
Stripes are displayed and noise is heard. (Radio Interference)
This may be caused by radio interference generated by radio stations, personal computers, AV equipment or microwave ovens.
The following are not malfunctions:
The monitor emits a strange sound when the room temperature changes suddenly. This is only a problem if an abnormality appears on the screen as well.
If two or more monitors are operated next to each other, their images may shake or be distorted. This phenomenon is due to mutual interference; it is not a malfunction. Move the monitors away from each other until the interference disappears or turn the power off on any monitor that is not being used.
If a magnet or speaker is placed close to the monitor, the picture may shake. This is caused by the magnetic effect and is not a malfunction.
When the monitor is turned ON, the sound of a running motor may be heard. This is the cooling fan and is not a malfunction.
When playing back a video tape, the upper edge of the picture may be distorted. This is caused by skew distortion and is not a malfunction.
Vertical stripes may occur on a dark picture. This is caused by quantization noise (noise which occurs when a picture is digitized) and is not a malfunction.
