Like New Sylvania VCR Won't Accept Cassettes?

I bought this a few years ago, & rarely ever used it. Now when I got it back out to use; it won't take in a cassette. It lights up the little light, that's supposed to mean there's one in it. When you plug it in to power; the unit makes the noises of trying to work. Parts are moving within, as some are turning, & others are moving to a different position too. When the 'off' button is pushed; it continues to try the same. When I attempt to put a cassette in; it will only go in about 2/3 of the way. It's a model #KVS669K.
Looks to be in like new condition. Just can't put a video in to play!!
What could be the reason for it not accepting a video, when there is nothing already in it ??
