Broken RCA / phono jack - where to find new part?

it appears that the left channel is defective, repair or replace

You didn't include make and model TV; so only generalized answers are possible.

Typical RCA phono jacks like those shown in the blue box of the stereo amplifier below:

will accept cables to connect to other audio devices. The audio RCA jacks are color coded RED (right) and WHITE (left) for low level stereo signals. Some have YELLOW jacks for Standard Definition video, ORANGE jacks for AC3 Digital audio and newer amps have HDMI jacks.

Connect the TV's audio OUTPUT jacks and a stereo pair of unused audio INPUT jacks on the amplifier with cables that have ends that match each. Turn on the stereo & TV and select the input on the amplifier that matches the stereo pair of inputs you used to connect to the TV. Adjust the volume to hear the audio over your stereo system's speakers.

Use the HDMI or AC3 sources for superior audio - including 5.1 (or better) Dobly Digital when possible. Otherwise, a standard 2 channel stereo program will be heard.

I hope this helps & good luck!

Unless the jacks have physically broken, replacing them is not the solution to the problem. Generally if both channels are dead, then you will find that a pre-amp IC has failed. This can be found by simply following where the jacks enter the PC board then following the circuit till they go into an IC.

Normally you should have a stereo "line" connection. The cable consists of a pair of "RCA male connectors" on each end of the cable, "RCA" is the style of the connectors, usually one red and one black or white on each end.. "Line" refers to the type signal and voltage level of the signal. The tuner should have a pair of output jacks labeled as such and also labeled Right and Left. The power amp should have similar jacks labeled "tuner input" or "tape in", "phono in" etc. don't use phono or "mic in" if that is a choice. Use tuner in or tape in. Connect the same colors to the same channel on each unit, ie, red to right and black to left on each unit. On the amp you may have the option to select the input source. Select the one you are using for the tuner. Turn on the tuner and the amp and listen. Good Luck.

There is an Aux input on the B & O. you can connect the I-pod to through this input. You will need a 3.5mm phono to 2 RCA cable connector. The phono jack goes to the I-pods headphone socket and the RCA ( Red & White ) jacks goes to the B & O Aux input.

If you want to amplify the sound you will probably need an adapter. You will use the audio output jack on your computer to an input jack on your receiver. There are usually several different inputs on a receiver but most use RCA phono plugs. The best choice input jack one the receiver is the one that says "AUX". You can buy the adapter cord at any Radio Shack. You will need to be sure to ask for a 1/8 inch stereo phone plug to two RCA phono plugs. This will split the stereo signal into left and right channels for your receiver.

Power amplifiers usually has only single input RCA input left "white" right "red". The preamp has plenty of input and output jacks, the proper connection is the one labeled "PREOUT" which usually located far from the group of rca jacks "PHONO,TAPE MON. REC OUT" etc. try it, it doesn't harm anything

If both speakers work okay on other inputs .Then cable from pre-amp to amp and main amp are okay. If phone RCA jacks go directly to electronics board .Then its possible solder on phono jacks need to be resoldered or other connections in that section.If unit needs repair you can also purchase a phono preamp from radioshack hook up your and use it on other good inputs such as CD etc..Please note PHONO inputs are only for turntables .If a non turntable input such as CD,TAPE,TV Etc is used on PHONE .Then you will overdrive this input .

swap your RCA's input to the amp. Does the channel that works switch to the other side? If so, then the problem is either your rca wire, or in your source unit. (try the wire first). If the same channel still is out, then problem in the amplifier or speakers. Move to swaping the speaker wires, right to left, and left to right... If problem same, then trouble is AMP, if problem moved, then trouble is speaker. If amp, remove amp, troubleshoot amp... (there are 3 basic parts to any amp... Power supply, input section, and amplifier section...) You know it's not the power supply because the sound is good on at least one channel, and most alll amps use one power supply for all channels, so if one channel sounds good, then you can rule out the power supply. Second, when an amplifier fails (usually, 90% of the time or more) it will result in a shorted output transistor or some other nasty condition that will blow a fuse, or toast a supply almost instantly, and again, your amp powers up, so odds are that the amplifier section of the amp might be ok. (no guarantee here, it's just the odds...I'd say it's like a 40/60 thing.... This leaves you to focus on the input section. First rule out the simple things... bad wiring, (rca, or speaker), bad speaker, bad source. Then rule out the simple things at the amp... broken rca input connectors (inside the amp at the PCB where the solder is) or outside the amp, where the jacks may have been crushed. Then rule out broken speaker terminals, where they can be cracked inside at the board where the solder is in the same way. After all this, you need your amp serviced by a qualified tech.

You can buy replacement panel mount RCA (phono) jacks directly from your local radio shack if you have one, or on www.radioshack.com a 4 pack is less than 5 bucks, then you just have to have someone who can solder pretty well and TADA!! new plug in the amp.
