Simple Diagnosis of DV
Possible causes
Defective IC102 (1394Link & DVcodec)/
IC108 (1394PHY), improper connection between IC102 /
IC108, defective soldering, defective power supply
, etc.
Defective DV
terminals, improper connection of the DV
-
terminal board, defective IC108 (1394PHY), defective
cables, an IEEE 1394 device other than the DV
device
connected.
Defective IC102 (1394Link & DVcodec), defective
soldering, defective power supply
, etc.
Defective DV
terminals, improper connection of the DV
-
terminal board, defective source device
defective IC102 (1394Link & DVcodec), IC108 (1394PHY)
Note:
As to a model having the Input Line System setting, if the
setting and the actual input signal system do not match, no
picture appears.
Recording cannot be performed for a copy-protected
source.
An audio signal with 44.1-kHz sampling frequency is
muted.
Defective IC101 (DV
specific V
ideoEncoder),
defective
soldering, defective power supply
, etc.
