I had same problem, while transferring media from TRV-16 to DVD, tape would not play, then would not eject. This after transferring several tapes to DVD. I tried several things over the last couple months that did not work before finally getting it open today. It did me no good to remove several of the outer panels that were each held by two "tiny" phillips head screws each. Went to the internet, found your post, also found a post that referred me back to SONY page which follows.......
Follow this procedure to troubleshoot if the cassette compartment will not open or the tape is stuck and will not eject.
your camcorder model has a RESET button, first try pressing this
button. If there is no RESET button, or pressing the button does not
resolve the issue, continue with the troubleshooting steps below.
- Turn off the camcorder.
- Remove the battery from the camera.
- Remove the AC power supply from the camera.
- Slide the power switch on the camera to the VTR , VCR or CAMERA mode for 15 seconds.
- Slide the power switch back to the OFF position.
- Connect the AC power supply to the camera.
- Attempt to open the cassette compartment.
"NOTE: If the issue is still unresolved after completing all of the troubleshooting steps, service may be required."
After I did this, I could hear a whirring sound when I hit eject, although nothing came out. While the whirring was going on, I pulled up and out with constant pressure and the cassette holder opened. The tape had jammed apparently as the little protective plastic tape guard was jammed partially open when I pulled the cassette out. Good Luck and don't be afraid to put a little pressure on the door if you can hear the door trying to open.
Now I turn to recovering the tape, but having grown up with cassette decks, don't believe it will be a problem.
