See that the safety tab on the video cassette is still intact.
Check the aerial and its connections.
Set the recording start/stop time correctly.
Has there been a power supply interruption before or during Timer recording? If so,
the timer will have lost details of the instructions you gave it and it will not function.
Try reprogramming again.
Check that the video cassette tape has been recorded on.
