Adding speakers to tv with no audio output

Adding a headphone jack creates a shock hazard, but you already have one so you'll have no problems. To connect the speakers you'll need an amplifier of some sort, doesn't have to be anything fancy. You may need a couple resistors to match the impedance but that may not be nessesary.

Another possibly neater option is to get a VCR with stereo audio out and use that as the tuner.

Easy way out: buy PC speakers (intended for connection to PC - soundcard) - they usually have a 3.5mm input jack that can be plugged into the headphone output (use converter if this output is 6 mm). Headphone jack should be isolated from hazardous voltages.

Since you cannot use powered speakers due to lack of power outlets where the new speakers are required you cannot use a wireless transmitter receiver setup. This means that you will be limited to directly connecting your new speakers to the TV, and this may be a problem depending upon your technical ability and the TV audio stage capability/wiring. It is technically fairly simple to do but it requires a fair bit of effort and appropriate knowledge.

I suspect that because the TV set only has a headphone jack you will not be able to connect external speakers directly. It is probable that the existing headphone output jack isolates the internal TV speakers when the headphones are plugged in (it should be wired like this), AND there will be series limiting resistors to reduce the maximum level being fed to the headphones. These resistors will need to be bypassed in order to drive external speakers so this would mean delving into the innards of your TV set. Unless you are familiar with TV servicing then don't do it yourself.

You will need to select external speakers having the same impedance as the internal ones (this data may be stamped on the internal speakers or it is in the TV user guide spec - possibly 8 ohms). You also need to select external speakers which will be as efficient as possible given the limited power output of the usual audio output amplifier in most TV's, but this rating should also be in the spec - say speakers rated at 5 - 7W RMS.

Now if the headphone output jack is a 3.5mm unit, as I suspect, then you won't be able to wire your new speaker cables into a 3.5mm plug, since this type of plug just isn't designed to take other than the small diameter cable as used on headphones. Your new speaker cables, being much longer, will most likely be stranded figure eight flex cord so you will need to make a suitable adapter box to expand the 3.5mm plug connections out to two sets of connectors suitable for stereo speaker cables. There aren't any off-the-shelf items to do this that I know of so you will need to be handy with electronics construction techniques and components.

If all this seems too hard for you then you won't be able to achieve your aim of connecting external speakers to your TV unless you use powered speaker units and an A/V transmitter setup.

I would find a small-ish stereo amp, put it next to the tv. connect the tv headphone out to its tape input (with 3.5mm jack to 2X RCA phono plug lead). Then wire up two speakers from the amp to the listening area.

Powered computer speakers are an easy way to go.
