Hello everybody,

We have an old XL1 and it's exhibiting these problems. The problems show up from time to time. When the camera's being shot, everything appears normal as seen through the EVF. But when the tape is viewed either through the XL1 or through another camcorder, it looks like the camera can't record to the tape with all the fields. It looks like it's skipping every other horizontal field.

The shot above was good when seen through the EVF as it was being shot.
But when later played, exhibited the blue horizontal bars... as if the camera
was not able to record on tape those missing fields

Again, the camera was shot but this time, using a used tape. The two videos
can be seen here with alternating fields.

What is the problem? Should I have the head aligned or replaced. (The guys at Canon service center told me they don't replace just the head but the whole recorder unit assembly) Is it the mainboard? Thanks guys.

Have you tried cleaning the head? I noticed when you mentioned it was an old xl1. Perhaps that could be the problem? Hope it helps!

The problem occurs sporadically. I think if it's only a case of a dirty head, it will happen continuously. Don't you think so?
