I just purchased a new Apex stereo TV/DVD combo with many bells &
whistles EXCEPT a headphone jack. Have any of you readers been able
to successfully install a stereo headphone jack into a stereo TV?
Thanks.
Yes, I have. One thing to watch out for is that both of the speakers'
"ground" or "return" lines are common, i.e., electrically the same
point. I forget what the jack is called, but it's got 5 terminals:
The sleeve, obviously, which is the speaker common. Then it has two
contacts which contact tip and ring, but they get their signals from
the other contacts. When you push the plug in, it disconnects the
speakers and goes to the phones.

When you plug in the plug, it opens the contact. There are two of
these circuits in the jack.
Good Luck!
