Hi,
Sony CCD-FX630 is 1994 model and it got problem of leaky electrolytic capacitors on its circuit boards.
Camera needs to replace all electrolytic capacitors on its circuit boards to work again.
Regarding no ejection of tape, this is because video head motor and capstan motor is not rotating ( because of capacitors) and I'm sure power supply in camcorder is not providing proper voltage too.
I been repairing Sony Camcorders since 1992 and have came across many times with this leaky capacitors problem in different models.
If you want to fix camera by yourself, you need to get Service Manual, solder iron to unsold bad capacitors and sold new capacitors, precision screw driver set to apart camera.
You can download Service Manual of CCD-FX630 from
Manual Zone for small fee and required electrolytic capacitors can be purchased from
HERE. Capacitor image is also there.
