The following are not malfunctions.

•When a still image is displayed for a long time, it may remain indistinctly on the screen after the picture has changed. Though the remaining picture will disappear after a while, there may be a case that it remains for a long period depending on the length of time the still image was displayed for. This is due to the characteristics of the LCD display and is not a malfunction.

•Red spots, blue spots and green spots on the panel surface are a normal characteristic of LCD displays, and not a problem. The LCD display is built with very high precision technology; however, be aware that a few pixels may be missing or constantly lit.

•The following symptoms are problems only when pictures or sounds are not played back normally.

–A slight electric shock occurs when you touch the monitor.

–The top and/or rear panel of the monitor becomes hot.

–The monitor emits a cracking noise.

–The monitor emits a mechanical noise.
