I recently bought a Samsung 40" lcd, led television.

The sound quality is bad when the volume is turned up.

All the jacks are input. I'm pretty sure that I can open it up and identify the speaker wires.

What I don't know is how to tap into the speaker circuit.

I assume that I'd use speakers with their own power source as the remote speakers. Any advice? Thank You

Peter

Consumer electronics support is off-topic, we are focused on electronics design. I wish you great luck, I hope you find an audio output. – Kortuk♦ Jul 14 '12 at 4:06

Most of the TV sets have a SCART output, instead of opening the TV set you could just buy an adapter (SCART to RCA) that you could connect to an external amplifier, or you if you want to do it yourself you could use the SCART audio out signals.

The tv has no output connections of any kind. What I'd like to know is how to best break out the speaker wires. Thanks for the attention. – Peter Stewart Jul 14 '12 at 3:23

Since you did not provide a model# I looked up the closest model to your dsecription and indeed no 3.5mm output jack.. But you have 3 other options.

  1. RCA phone jacks to ext. stereo amp.
  2. TOS optical to TOS input on Audio processor.
  3. Audio out on USB port? just a guess. not likely.

This is what I read on your spec.

 *2 x USB 2.0 ( 4 pin USB Type A ) - side ¦ 4 x HDMI ( 19 pin HDMI Type A ) ¦ 1 x composite video / component video input ( RCA phono x 3 ) ¦ 1 x VGA input ( 15 pin HD D-Sub (HD-15) ) ¦ 1 x digital audio output (optical) ( TOSLINK ) ¦ Audio line-in ( mini-phone stereo 3.5 mm ) ¦ 1 x component video input ( RCA phono x 3 ) ¦ 1 x network ( RJ-45 ) ¦ Audio line-out ¦ Audio line-in ( RCA phono x 2 )*

If your device truly has no output than my best advice is to get an external audio receiver! Don't even bother plugging audio into the TV if the audio is bad. You're going to have to do some extra gymnastics every time that you switch input (change both the receiver and the tv input together).

Alternatively just get some adapter cables that break the audio out to a 3.5 mm jack and plug in there?

What's the point is breaking out the TV speaker connections, voiding your warranty on your new TV, and building a whole circuit if you can just get some external speakers and a few bucks?
