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.
OLED Panels
The OLED 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, or flashing. In addition, over a
long period of use, because of the physical
characteristics of the organic light-emitting
diode, such “stuck” pixels may appear
spontaneously. These problems are not a
malfunction. Note that any such problems
have no effect on recorded data.
Due to the characteristics of the material used
in the OLED panel, permanent burn-in or
reduction in brightness may occur.
These problems are not a malfunction.
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 image
sensors and is not a malfunction.
The white flecks especially tend to be seen in
the following cases.
• When operating at high environmental
temperatures
Aliasing
When fine patterns, stripes, or lines are shot,
they may appear jagged or flicker.
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.
Flashbanding
The luminance at the top and bottom of the
screen may change when shooting a flashlight
beam or a light source that quickly flashes.
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.
The flicker can be reduced using the flicker
reduction function of the unit (page 65).
Notes on the Display
• Pictures on the viewfinder screen and
outputs may be distorted by the following
operations.
– Changing the video format
– Changing the FPS frame rate
– When genlock is applied
• When you change the line of sight in the
viewfinder, you may see primary colors red,
green, and blue, but this is not a defect
of the unit. These primary colors are not
recorded on any recording media.
Fragmentation
If pictures cannot be recorded/reproduced
properly, try formatting the recording
medium. While repeating picture recording/
playback with a certain recording media for
an extended period, files in the media may
be fragmented, disabling proper recording/
storage. In such a case, make a backup of
clips in the media then perform formatting
of the media using TC/Media > Format Media
(page 76) in the menu.
