Symptom The date and time are not displayed. No output from the [Y/VIDEO], [PB], and [PR] video signal output terminals. Incorrect display on the viewfinder. IEEE1394 connection between the camera recorder and the external device cannot be established (e.g., no image on the camera recorder and/or external device). When the camera recorder is in the Media mode (SD Card mode), pressing the [CAM/MEDIA] button does not switch it to the IEEE1394 Input mode. Action ● The date and time are only displayed on the STATUS 2 and STATUS 3 screens in the Camera mode (during shooting). ( A Page 104, 105) ● Is [Output Terminal] in the [A/V Out] menu correctly set? (A Page 92) ● Is the LCD monitor used with [LCD + VF] in the [LCD/VF] menu set to AOffB? (A Page 88) ● Is the operation mode correctly set? (A Page 8) ● Is the [INT/EXT] IEEE1394 interface terminal switch correctly set? ● Is [System Definition] in the [Record Format] menu correctly set? (A Page 75) ● Check the connection, such as by removing the IEEE1394 cable and inserting it again, or by reconnecting the power. ● Is the power of the device connected to the [IEEE1394] terminal turned ON? If the power of the connected device is OFF, the camera recorder does not switch to the IEEE1394 Input mode. ● Is [System Definition] in the [Record Format] menu set to ASD (DV)B? (A Page 75) When the SD video system is in use, the camera recorder is unable to recognize the IEEE1394 connection in the Media mode (SD Card mode). Turn ON the power of the IEEE1394-connected device in the Camera mode, followed by switching from the Media mode (SD Card mode) to the IEEE1394 Input mode using the [CAM/MEDIA] button.
