FIRST..... try another pair of headphones.
If that doesn't work then TAKE your television to a service shop for what
should be a fairly inexpensive repair.

I have a Sharp 28lf-92h tv and when I plug in a headphone I get no sound
but
the built in speakers are still working. Jiggling the headphone jack plug
around in the socket has no effect. Any help please, thanks.
