Default JVC VCR- Tape is immediatley ejected. HR-S7600U

Need help.

After watching a movie. Tape got stuck and would not eject. Unit
displayed "auto" and would not turn on.

Opened unit, removed tape. Now, (a different) tape goes in, it looks like
the unit is starting but then the tape is ejected after a few seconds and
the unit disply "Auto". The power switch does not turn unit on. after a
few minutes the "auto" also disapears, and only a few dashes show in
display.

Any guidance?

If mechanical alignment and gearing/idler/belts all are functioning
properly, then I would look at the mode switch. Many can be removed and
cleaned and then reinstalled. The mode switch provides electrical feedback
to the controller to tell it when the cartridge loading and unloading
mechanism is in the desired position. If the mode switch gets dirty and the
wipers don't make good electrical contact, then the unit determines
something is not working correctly so either automatically ejects the
cartridge, or depending on the unit, sometimes just shuts down/off.

The oldies that use an incandesant bulb for a light source instead of
IR diode might have a bulb out.

Any machine that would use an incandescant lamp is 20 years older than the
OP's machine. The HR-S prefix is a Super VHS model.
