The following are not malfunctions:
• When a still image is displayed for a long time, it may remains on the screen after the picture changes. This is
due to the characteristics of the LCD display and is not malfunction. The remaining picture will disappear after
a while.
• The 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.
