Question

my panasonic PV-L659 only records sound. i can view the picture threw the view finder and on the lcd screen, but when i play back what i recorded i only get sound and black and white fuzz on the screen. is this a video head cleaning problem? i tried to find a head cleaner for a vhs c tape but can not find one.
