This Sylvania was made by symphonic Funai, and you may want to try holding in the eject button while powering it on. The cause of the problem could be anything from a defective tape to a bad gear inside the mechnism throwing it out of time or even a bad/dirty mode select switch. Unless the set is in warranty which I very much doubt, it may not be worthwhile getting repaired. The tape cannot be "forced" out of these machines without getting them out of time and the symptom would be the same as you now have. If it's not that old, maybe you could get Wal-Mart to take it back.
