Re: pioneer Model Is21 stereo

Switch speaker wires if sound switches then amp probably has a final amp ic.output problem. Try balance control and tape dubbing or loudness buttons to see if any are dirty.
May have to get repairs at a shop if the amp is worth saving.

Good Luck

JVC RX 515 receiver

The fault is on the tuner section of the receiver. FM radio signals are processed by one IC in the tuner section. Since you can hear the station, it won't be that one. The only other is the Stereo Decoder. The radio signals are passed to this and that splits the signal into the left and right channels. If you can't here one of the channels then the Decoder IC will have failed. If you are lucky the board will label the IC, otherwise find the tuner section (look for coils). Then read the numbers of the IC's. If there are several enter each number into Google and find what it does. If you find one that says "decoder" or "FM multiplex" that is the one you need to replace.

I have a Sony Amplifier [model TA-AX380] and other components of CD player [model DCP-C40], AM/FM Tuner [model ST-JX380], FM Stereo/FM-AM Receiver [model STR-AV570X], and Stereo Cassette Deck [model...
Hi above are links for manuals, these may help..
When one wires up anything it is all usually color to color output to input... usually RED & WHITE stereo audio.
Now we would start with our Tuner this the CD player, & Cassette deck, will wire into the Amp's INPUTs , red - red & white - white, these go into the Stereo INPUTs on the AMP... 1, 2 & 3 and be selected via the input selector on the AMP.
Now after all these in's and out's are wired we need to wire our speakers, this too is simple, locate the outputs on the Amp, and wire accordingly, Plus to Plus and Negative to Negative... each speaker has two wires a Plus, + & a Negative -
All will/should be clearly marked and it will be easy to do. You will need patch leads, one set each for each unit, these will be a pair of cables, usually Red & White with RCA jacks on each end, as related these go color to color from the RCA OUTPUTs Sockets, of the signal suppliers, ie: Tuner, FM stereo & Cassette deck... these ALL will wire into the Main Amplifiers INPUTS, usually at rear of unit, and clearly marked, after this is all done, then as related again now connect the Speakers, again the OUTPUT on the Amp will be clearly marked, as output and + & -, + & - (two sets), one for each channel.
Now each INPUT is selected ON the AMP, and it's output will then be directed to the speakers attached to the Amp..... Just wire and test one at a time, and i am sure you will prevail.
Hope this helps.

Radio tuner quit

There are many reasons for this to occur dependent upon the model of the unit. Repairs can cost anywhere from $10-$50 for parts. Can you update this with the model number so we can provide potential repair options?

No stereo signal out from yamaha p 2500 s

It's unclear what type of connectors are on the end of the cables(s) coming from your computer.

This amp only works with mono 1/4" TRS and XLR connectors, not standard RCA connectors.

Did you try the Right one in the Left Channel to see if the Left Channel worked?

Refer to the following manual and read up on the connectors (page 7) and the use of the Stereo/Parallel/Bridge Switch (page 8). When it is NOT in Stereo Mode the unit only uses the Right Channel controls and input.

Use this switch to select the operating mode.
• STEREO mode
Channels A and B operate independently (as with a conventional
stereo amplifier). The Channel A input goes to the Channel
A output jacks, and the Channel B input goes to the
Channel B output jacks.
The Channel A input signal is output through both the Channel
A and Channel B output jacks. The Channel B input jacks do
not function. Channel A and B volumes can be independently
• BRIDGE mode
The Channel A input signal is output from the BRIDGE output
jacks. To adjust the volume, you must use the Channel A volume
control knob.

Cant figure how to hook my stereo up

what to remember is pre-amp is before the amplifier then the amplifier to the speakers, go this route, Tuner for radio? from the radio tuner out go to the pre-amp tuner input, then from the pre-amp OUT go to the AMPLIFIER IN, tuner, cd, dvd, tv, any source, if you are using a 2 channel amp and pre-amp this is relatively easy, a little more detailed for multi-channel pre-amps and amps but follow the same path, sound source signal ie. tuner to pre-amp, pre-amp out to amplifier and speaker hookup to amp channels,
