Canon zr700 won't play tape

No, it cannot.

It is not possible to play directly on this camera as it is an old model.
You should get a cassette player and put the tape in it and connect it to your TV.

According to Canon's specs, the ZR600 uses DV tapes, not memory cards.

The monitor you view while recording does not read from the tape where the problem is located, that's why you are not seeing them during recording.
Since they are not visible while recording, the video section is healthy, only the recording is faulty and it is unlikely you can do anything at home to correct it.
This may be a common problem and perhaps Canon is familiar with it.
I recommend you call their service line directly:

THIS SOUNDS LIKE MAYBE A DIRTY HEAD.. OR A LOOSE CONNECTION BETWEEN THE LCD AND DAUGHTER BOARD.. MOST LIKELY A DIRTY HEAD, TRY A CLEANING CASSETTE

Open iMovie and set it to capture DV. (Click the camera shaped icon opposed to the siscor scissor shape) When you see a blue screen that says (camera connected) and the image pops on screen of image from tape on camcorder set in play mode, you hit the import button and it begins to capture digital movie using DV compression of whatever you have on tape. You should be able to control your camcorder with the video controllers underneath the project window to make selections for the in and outpunts on the tape you wish to capture. Then switch to edit mode by clicking on the scissor button and import the movies you just captured or use them from the clips menu, etc. renedr movie back to tape, if you wish by clicking back and forth from edit mode (scissors) and capture mode (camera silo) and render to and from tape.

Hi, You usually get an EJECT TAPE when the camcorder has found an internal problem and either the videocassette or the camera itself has developed a problem. In you case, it looks like you tape has a problem. Daniel
