by RMIKA1 / January 30, 2013 3:16 AM PST

RECEIVER HAS INPUT IN FRONT FOR HPHONES, BUT WHEN U PLUG THEM IN THEY KILL SPEAKERS. I AM HARD OF HEARING AND DO NOT WANT TO IRRITATE OTHERS WITH THE VOLUME, SO I NEED THE SPEAKERS AND THE HPHONE TO BE ACTIVE AT THE SAME TIME! TV IS SAMSUNG HLR5668WX/XAA AND DOES NOT SUPPORT HPHONES. HOW OR CAN I GET AROUND THE HPHONE JACK KILLING THE SPEAKERS??? THANX

You'll need an electronics technician

To create a hookup to the receiver if it does not have a "monitor" output. Don't be confused by consumer goods like this. That is, for special applications or needs you use the folk that know how to fix this issue.

But you have to use your better electronics technician to create the cable or connection you want. It's pretty trivial but in the land of consumer outlets (Best Buy) they are often clueless if you can't get it off the shelf and even then they can't find a cable I ask for. That is I have to ask where are the cables and find it myself.

Again, I wrote it can be done. You only need a good technician.

I would not need a schematic.

The headphone jack is a pretty well known thing. And it's just a matter of either tapping the signal from the speakers and using a potentiometer to drop the signal level then off to a headphone jack or adding a headphone jack in the receiver wired in parallel to the existing jack but only with 3 wires. The common jack has a switch in it that we don't need but we need the ground and the two other signals. That's all of three wires and a jack. How hard is that?

https://www.google.com/search?hl=en&as_q=speaker+to+headphone+adapter sees how the connection to the speaker jack is well discussed. That's why I don't write further about that.

Schematic probably won't be as useful...

as just opening the TV and take a look. Basically the cutting on/off is done at the "JACK". So I don't think you can just fool it. You need to rewire the circuit instead. It can be done but not as simple as you might like. Good luck.
