The subject VCR shuts itself off approximately 3 seconds after it powers on
when the 'power' pushbutton is depressed. While it is on, it displays
channel info. It does not accept a video cassette. Anyone have any
helpful suggestions? Thanks in advance!!

Check the alignment of the tape mechanism, gears, mode switches, and
any optical sensors per the diagram in the service manual. If it is
one of the newest under $100 VCRs then a service manual may not be
available, it might be one of the throw away exchange under warranty
items.

How about a JVC VCR-DVD combination where the VCR rewinds the tape by
itself when the unit has been on a long time! Spooky. You go to
record something and you end up taping over something you want to keep.

Think about the problem logically.
When would hte vcr normally rewind the tape? When it senses you are at
the end of the tape.

Assuming you do not have a real junk tape in the unit causing excessive
light to pass through the tape. You need to troubleshoot the end of
tape optical sensor. BTW the tape entry door missing can also cause
this on many cheap vcrs from the ambient room light.

I should've mentioned that I'm not playing the tape. I just have the
VCR on to pass audio to my surround system, like when I'm viewing
NASCAR. All of a sudden, for no reason, the tape will start rewinding.
And NO, it is not anywhere near the end of the tape.

It may be getting an IR signal somehow, from a TV remote, perhaps, that
commands the action.
