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.
