 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.
