OK, I've got an LCD TV with two 8 ohm 10W speakers (internal). For the past two years I've been running the audio outputs to a set of Logitech Z-640 computer speakers with subwoofer - http://logitech-en-amr.custhelp.com/...name/Z-640.pdf
. I only turn the speakers on when I want to watch a movie/concert/etc. The audio out on my TV is not controlled by the volume on the remote control. This means the volume is kind of screwy because I have to set it so it is low enough for big explosions but loud enough to hear conversations (you get the idea). If the phone rings and I want to turn down the TV I would have to jump up and adjust the computer speakers because turning my volume down on the remote only affects the internal TV speakers.
SO, I decided to add a 1/8" stereo jack to the back of the TV, splice into the internal TV speakers and output to my computer speakers. I've done this before and didn't think it was any big deal but it isn't working as planned. The audio jack I bought was this (radio shack 274-0246):
When you plug the phono plug into the jack it opens the circuit going to the internal TV speakers and closes the one going to the external computer speakers. So far so good. I spliced pin 4/5 into the right speaker + and spliced pin 2/3 into the left speaker +. Then I grabbed all 4 negative wires, soldered them together and hooked them to pin 1.
I plugged the external speakers into my new jack and changed the TV volume from 0 to 1. I could hear a "pop". Switching from 1 to 0 also made a popping sound. I could put my fingers on the internal speaker cone and feel the cone pull in / out with the pop. After playing with it for a minute the speakers started popping at a regular interval. I'm guessing the amp was turning on/off from time to time. So, I clipped the wires going to the internal speakers (didn't want to blow anything) and now the sound is just coming through the external computer speakers. I still get a pop (through the external speakers) when changing channels and this is not something I ever got with the regular internal TV speakers. Anyone have an idea of what I need to do to fix my problems or a better way to set this up?
