Check that you put your jack in the right socket (line out) and open volume control(right click on speaker icon)-confirm no mute box is checked and faders are in up position.

Goes straight to protect mode, detached speakers, still same problem


HI, if the unit is in protect mode then there may be the possibility that the speaker wires may have a short circuit in them or that the amplifier section may be damaged....you can remove the radio from it's sleeve and check the wiring behind the unit...this also would have to be done to see the model number and serial number...it should be on either the top or bottom of the unit...the speaker wires for this unit are the white, gray, green, and violet...each with another of the same color but has a black stripe in it...the black stripe is the negative side of the speaker wire....you can disconnect these wires, then turn on the unit to see if it comes out of protect mode...if it does, then there is either a bad wire somewhere in the car or a bad speaker...if the unit stays in the protect mode, then you will have to take the unit in for repair, as this indicates a circuit failure

One of the more confusing car stereo problems can be when an amplifier goes into protection mode. One minute it's working and the next minute it's not, usually with the green power LED on the amp turning to red or orange. Here's a brief troubleshooting method that will hopefully help you if your amplifiers ever go into protection.

1. Try to determine the cause. Amplifiers can go into protection mode for several reasons. Knowing what happened before it quit working can help determine how to fix it. Did the amp malfunction as soon as it was turned on? Did it happen after blasting for hours (may be thermal overload and it needs to cool)? Did it cut out after you hit a bump (a wire connection may have come loose)?

2. Tear it down. Get the amp down to it's most basic state. Remove all of the speaker wiring and RCA wiring and leave only the power, ground and remote leads connected. If you still have a problem in this state then either your amp is defective or you may have an installation problem such as the amplifier touching metal.

Remember that an amplifier should only be connected to the vehicle through the power and ground terminals. Mounting the amplifier to the metal of the vehicle, including putting the mounting screws into metal, can cause problems for your amplifier. Always mount the amplifier to a non-conductive surface. An easy way to accomplish this is to mount the amplifier to a wood board and then mount the board to the vehicle. Don't let the amp touch the screws used to moun the wood board and don't use screws so long to mount the amp that they go through the board and touch the vehicle.

3. If the amp is OK in this torn down state start reconnecting wires until you find what causes the problem. Add the RCA cables first. Then add the speaker wires one at a time. If the speaker wires cause the problem then they are probably touching metal. Check to make sure that a speaker wire isn't being pinched somewhere between the amp and the speaker. Also check that the speaker wire or speaker terminals aren't touching the vehicle metal near the speaker opening. Rear decks and door panels can easily touch unprotected speaker terminals if not properly installed.

If you believe your amplifier is defective contact the manufacturer first. Many have flat repair rates that are very affordable and cover parts and labor as well as return shipping. However local repair shops may be cheaper if it is just a small repair. Compare the manufacturer's repair rate to that of a local shop. If you don't know the reputation of the local shop it may be better to send it to the manufacturer who will have working knowledge of the amp and parts readily available.

Hope it helps..

I wasn't blaming you for anything, just pointing out that human presence opens up a zillion failure modes that aren't there when something just up and fails.

The replaced part is also suspect now. You COULD just call it quits on this unit or continue to diagnose the problem. We still don't know if the breakdown is in the preamp side or the amp side and there is not a lot of flexibility in this product to separate the two.

That it is so predictable is actually a big plus. You could try various sources and bypass anything you can to reduce the potential failing circuitry. The cleanest test will always be its own FM.

OTOH, a unit that old has lived a long life. Maybe its time.

And you don't think the speakers are wired wrong. Re-investigate or reposition the speakers you THINK are Front to the Rear and go on from there.

Pioneer VSX-21 Elite: Issue: after playing music softly for about 1 minute the machine goes into "overload" mode. Unplugging will reset this. Keeps going into this overload mode, acts like...


Check to see if the unit is getting unusually hot.
If it is, check the impedance of the speakers and speaker wires to make sure they aren't shorted, or close to shorted (ie - partially blown speaker).
Try running the unit with the speakers detatched to see if it still happens.
If the unit gets hot with no speakers and goes into overload, then we need to start checking the components inside.
Look for electrolytic capacitors that are bulged at the top, or that have discolored the circuit board at their base (leaking).
Any caps doing this will need to be replaced, and will likely solve the issue.
If there aren't any, or if that doesn't solve the issue, start checking the transistors at the output.
Look to see if there is a DC voltage riding on them, and make sure they aren't shorted out.
If the power amp is a hybrid chip, see if you can find one cheap and replace it if you can't see anything else wrong, or if one of the hybrids is overheating a lot.

A CD player has at least an analog RCA output. Plug that into "CD", which is not literal. It could work for anything expect a turntable. Just don't use anything but a turntable on PHONO.

Speakers = plus to plus, minus to minus, using any available lamp cord-like wire. One speaker to each terminal pair.

Use the built-in EQ and volume control with restraint. DON"T do the rookie thing of raising the bass all the way or cranking the volume to '11'. Distortion will KILL the speakers and possibly the amp.

Check to make sure your wires aren't crossing on your speakers or if any of them are loose. Could easily be the cause for knocking out your speakers. That's the easy fix. Other than that it sounds like a computer issue. I'd take it back to where I got it from if it was me and it had only been two weeks.
I am kind of curious, though. Why aren't you using all seven channels? You really shouldn't leave channels open like that.

Page 10. The S-302 uses a proprietary D-Sub25 system cable to the DSW-S302 subwoofer. Don't know if or why it has more than 2 active conductors. The other speakers have removable cable ends so they might work just fine.
