Troubleshooting
164
Video noise appears on screen.
- Keep a distance between the camcorder and devices that emit strong electromagnetic fields such as near powerful
magnets and motors, MRI machines or high-voltage power lines.
Horizontal bands appear on the screen.
- This is a phenomenon typical of CMOS image sensors when recording under some types of fluorescent, mercury or
sodium lamps. To reduce the symptoms, set the shutter speed to 1/100 (A 58). This is not a malfunction.
Audio cannot be recorded.
- An external microphone connected to the XLR terminal requires phantom power. Set the XLR terminal switch to
MIC+48V (A 81).
- The camcorder’s MIC terminal is given priority over the XLR terminals. To record audio from the XLR terminals, be sure
not to connect any microphones to the MIC terminal.
Audio is recorded at an extremely low level.
- When using the XLR terminals: The AUDIO LEVEL switch is set to M, and the recording level is set too low. When using
the MIC terminal: [Audio Setup] > [Audio Input] > [MIC Mode] is set to [Manual] and the [MIC Level] setting is too
low. Check the audio level meter on the screen or rear panel and adjust the audio level correctly (A 82, 83).
- The microphone attenuator is on. Turn off the microphone attenuator (A 83, 84).
Sound is distorted or is recorded at lower levels.
- When recording near loud sounds (such as fireworks, shows or concerts), sound may become distorted or it may not
be recorded at the actual levels. Activate the microphone attenuator (A 83, 84), or adjust the audio recording level
manually.
Recording Media and Accessories
Cannot insert the recording media.
- The CF card or SD card you are trying to insert is not facing the correct direction. Turn it over and insert it.
Cannot record on the CF card.
- A compatible CF card must be used (A 41).
- Initialize the CF card (A 43) when you use it with the camcorder for the first time.
- The CF card is full or it already contains the maximum number of clips (999 clips). Delete some clips (A 122) to free
some space or replace the CF card.
Cannot record on the SD card.
- Initialize the SD card (A 43) when you use it with the camcorder for the first time.
- The LOCK switch on the SD card is set to prevent accidental erasure. Change the position of the LOCK switch.
- The SD card is full. Delete some photos (A 142) to free some space or replace the SD card.
- The folder and file numbers have reached their maximum value. Set the [Other Functions] > [Photo Numbering]
setting to [Reset] and insert a new SD card.
Recording to and playing back from a CF card is slow.
- This may occur as video is recorded/deleted over time. Save your clips (A 132) and initialize the CF card (A 43).
Recording to and playing back from an SD card is slow.
- This may occur as photos are recorded/deleted over time. Save your photos and initialize the SD card (A 43).
Connections with External Devices
Video noise appears on a nearby TV screen.
- When using the camcorder in a room where a TV is located, keep a distance between the compact power adapter and
the power or antenna cables of the TV.
Playback looks fine on the camcorder but there is no image on the external monitor.
- The camcorder is not connected correctly to the external monitor. Make sure you are using the correct connection
(A 128).
- The video input on the external monitor is not set to the video terminal to which you connected the camcorder. Select
the correct video input.
The camcorder is connected using a commercially available HDMI cable, but there is no picture or sound from the
external monitor.
- Disconnect the HDMI cable and then restore the connection or turn the camcorder off and then on again.
