Thanks so much for the advise,thanks for taking the time.

I have a Quasar Palmcorder,vm-l-152.I have used it for several
years,here recently,when I start to record,it records for about a
second,and then the power shuts off,of the camcorder.I purchased a new
battery and had the battery charger tested,it is okay.Whether this is
helpful or not,if I take the tape out,not in the record mode,,of the
camcorder,the power stays on,but if I put the tape back in,without
being in the record mode,the power shuts off.Thanks so much for any
help you can give me.

Sounds like a mechanical or electro-mechanical problem, such as the
loading arms not fully extending, dirty mode switch, dirty/inoperative
tape movement sensor, or in some camcorders damaged ribbon cables that
feed signals to and from these items.
