Sony Handi-Cam TR57. After being stored for...

Sony Handi-Cam TR57. After being stored for a couple of weeks,the tape door, with tape in place has become stuck in the up position, and the tape cannot be either removed or pushed back down. The tape usually would come up when ejected, then shift outward, allowing the tape to be removed. Note: The battery was very good,and was fully charged when this happened, and still had over 650 minutes left of charge. I also used the wall power adaptor when trying to get the tape out. It is stuck halfway through the eject cycle. Anybody know where to tickle this thing to get it to finish ejecting? I have some experience with tape machines,vcrs, etc.,and can dismantle it if necessary with a little advice beforehand. This is and older model, but was enjoyable to use and should have more life ahead of it.
