About the LCD panels
The LCD panel fitted to this unit is manufactured
with high precision technology, giving a
functioning pixel ratio of at least 99.99%. Thus a
very small proportion of pixels may be “stuck”,
either always off (black), always on (red, green,
or blue), or flashing. In addition, over a long
period of use, because of the physical
characteristics of the liquid crystal display, such
“stuck” pixels may appear spontaneously. These
problems are not a malfunction. Note that any
such problems have no effect on recorded data.
On condensation
If the unit is suddenly taken from a cold to a warm
location, or if ambient temperature suddenly
rises, moisture may form on the outer surface of
the unit and/or inside of the unit. This is known as
condensation. If condensation occurs, turn off the
unit and wait until the condensation clears before
operating the unit. Operating the unit while
condensation is present may damage the unit.
Phenomena specific to CMOS image
sensors
The following phenomena that may appear in
images are specific to CMOS (Complementary
Metal Oxide Semiconductor) image sensors.
They do not indicate malfunctions.
White flecks
Although the CMOS image sensors are produced
with high-precision technologies, fine white
flecks may be generated on the screen in rare
cases, caused by cosmic rays, etc.
This is related to the principle of CMOS image
sensors and is not a malfunction.
The white flecks especially tend to be seen in the
following cases:
• when operating at a high environmental
temperature
• when you have raised the master gain
(sensitivity)
• when operating in Slow-Shutter mode
Aliasing
When fine patterns, stripes, or lines are shot, they
may appear jagged or flicker.
Flicker
If recording is made under lighting produced by
discharge tubes, such as fluorescent, sodium, or
mercury-vapor lamps, the screen may flicker,
colors may vary, or horizontal stripes may appear
distorted.
In such cases, set the Flicker-Reduction function
to Auto mode
In some cases, such phenomena may not be
improved with the Flicker-Reduction function.
It is recommend to set the electronic shutter speed
to 1/100 sec. in 50-Hz areas and to 1/60 in 60-Hz
areas.
Focal plane
Owing to the characteristics of the pickup
elements (CMOS sensors) for reading video
signals, subjects that quickly move across the
screen may appear slightly skewed.
Flash band
The luminance at the top and bottom of the screen
may change when shooting a flashlight beam or a
light source that quickly flashes.
Note on the viewfinder screen
Pictures on the viewfinder screen may be
distorted by the following operations:
• Changing the video format
• Rec Review
• Starting playback from the Thumbnail screen
• Reversing the viewfinder
• Switching the Expanded Focus display
Fragmentation
If pictures cannot be recorded/reproduced
properly, try formatting the recording medium.
While repeating picture recording/playback with
a certain recording medium for an extended
period, files in the medium may be fragmented,
disabling proper recording/storage. In such a
case, make a backup of clips in the medium then
perform formatting of the medium using “Format
Media”
in the OTHERS menu.
