    it plays perfect for a few minutes,i can turn it up loud with no distortion,works perfect at a low or high volume.the volume knob is smooth thru the range and doesnt distort when raising or lowering the volum.im only running two speakers,one per channel.

I would begin by re-booting the receiver. Your operations manual may have instructions about how to re-boot. The second thing I would address is the placement of you FM antenna. Perhaps when you turn on the FM band you may sit in a certain position relative to the placement of the antenna, which may affect your signal. The question would become even more complex if you get your 5 minutes of good FM sound when you turn on the receiver, or is it just when you switch from any other function to FM. This could be related to the heat factor in the receiver which affects the connections to FM function..

The problem you are having is the unit is going into protect.

You can try disconnecting all the speakers and then see if it turns on. If it does turn on you may only have a bad speaker.

Then just turn the unit off and plug in one speaker at a time. If it still turns on, that speaker is good. Keep doing this with each speaker until it goes into protect again, and then you know the last speaker plugged in is the bad one. Make sure you turn it off after checking each speaker.

If it still goes into protect with all speakers disconnected you most likely have a problem in the amplifier circuit.

I have the complete service manual in PDF format with parts list and schematics, but it cost $10.00
Let me know if you want to purchase it and I will give you instructions for that. I can give you a direct download link after purchase using PayPal.

If you would like any further help just let me know.

SOURCE: Pioneer sx-205 gives a overload

Does it play normal on any sources, or do you only have the tuner and CD for available sources?

There are many different things that can cause this type of problem.

It could be bad solder connections on in the amplifier circuit or power supply, it could be a bad speaker or a bad output channel inside the receiver if this happens only when it gets turned up loud.

The overload warning happens when the amplifier circuit has excessive current or DC voltage on the outputs. Unfortunately the only way to determain if it is the speakers is to change them with other known good speakers and see if it still happens. But before buying any speakers you need to have the receiver ruled out as the source of the problem.

It can also go into overload if you have the wrong type of speakers connected, or too many speakers connected. Each speaker jack should only have one speaker connected toit. If you are using for example, 4 speakers connected to the "A" speaker jacks meant for just 2 speakers, it will create a load to the amplifier that the amplifier is not rated for.
Look on the back of the receiver and it will have listed the proper impeadance for your receiver. Most will say:

8 ohms or more "A" or "B" speakers
16 ohms "A" and "B" speakers

That means you must use 8 ohm or higher ohm rated speakers if you are using only speakers"A" or only speakers "B", but can not use 8 ohm speakers if you are using speakers "A" and "B" at the same time. Then they must be 16 ohm speakers.

Two 8 ohm speakers in one speaker jack is a 4 ohm load, that is why you can not use more than 1 speaker per speaker jack.

I hope you found this information useful, and if I can be more help just let me know.

SOURCE: Pioneer Stero Receiver model SX-3700-

It sounds like your volume control pot has dust in it.You need to remove your cover from the receiver,spray pure denatured alcohol in the small openings in the back of you volume control dial and turn the knob all the way up and down several times and then blow low compressed air threw the same small openings while rotating your dial.That should fix your problem.Be sure you unplug your receiver before performing this procedure.

SOURCE: I have a 'vintage' (70's) Pioneer sx 535. What is

Depends on the connection on the back. Most older receivers used unbalanced 300ohm connections. In short, any speaker wire will do. Newer models used a "F" type connection (Coax end) which you can still cheat and get a 75 to 300 adapter at radio shack or any other local electronics store. Hope this helps.

How do i hook up an antenna to the pioneer sx-950


There are two antenna sources on the Pioneer SX-950.

Both of these outputs are located on the rear panel of the receiver. The AM is a permanent mount. The FM is standard RF/Coax which will run to your antenna.

Antenna Inputs: FM 75 ohm, FM 300 ohm
Am Ferrite Bar Antenna

Pioneer SX-2300 powers up, but no sound.


Does the output relay click about 5 sec. after powering on? If it does check if the tape2/tape monitor is on. Check speakers and wiring. Try headphones.

There aren't any fuses for the output.

If no relay then it probably needs output transistors and a few resistors.

Reciever only allows 2 channels(speakers) at a time.


If the amplifier is not receiving a surround sound signal, you will get nothing from the rear speakers and probably nothing from the front centre. Play a dvd in dolby surround and it will work.

Signal indicator brake lights and fm radio


You may have an intermittent switch or possibly a shorted or broken wire. As for the radio, I'd yank it and put an after market deck in. GM radios aren't known for their quality. But, you could check the back of the radio to see if the antenna lead is plugged in securely.
Hope this helps.
