how to connect a Sony wireless headphones MDR-RF912RX to a Samsung TV that has no headphone jack or connection..what do I need

Solution
If the TV doesn't have any audio outputs then you could connect a speaker to line level converter to the wires going to the internal TV speakers. That would give you a line level audio output for the transmitter of the headphones. If you don't want to use the TV speakers you would need to leave them disconnected or wire a switch to turn them on or off.
You don't.

Someone very skilled in electronics and soldering may be able to open the TV up, read the schematics, and tap in some sort of wireless transmitter or earphone port via the TV's speaker connections.

However, the TV's circuitry is probably not designed to even consider that sort of modication.

TV probably not even designed to be repaired to begin with.....

It may, however, be possible to tap the interceding devices for the audio you want. Many boxes and dvd players will have a section for audio out, which can feed into a 3.5mm adapter with a cable. Many 2.4ghz RF sets actually come with this, if not, you'd need to figure that out.
