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.
