Just recently, I'm having a problem with playback in my Sony Z1U HDV video camera (it's about 6 years old). When it's playing a tape it has shot in HDV, often the IMAGE doesn't show up on the screen (the screen stays blue), although the timecode is running. Or, the image may show up, but frozen for a few seconds - then the timecode skips a few seconds, and so does the image.
Does this mean my playback head is getting old?
I tried cleaning the head (with the Sony Headcleaning tape) but it didn't seem to make a difference.
