Bought the stereo 6 months ago, now the speakers won't work!!!! Please help!


Hi, when a speaker does not work, you might need to do some troubleshooting tips to know exactly where the problem is .

First you will need to test the speaker cone if it's working properly by using an AA battery and two wires to make sure the cone is working..

Connect one of the wires to the Positive side of the speaker, and the other on the Negative side, And after that use the battery to hear if the speaker cone will make a click sound.

If it doesn't make a click, that means the speaker cone is Bad, you will need to replace the speaker cone,
But if there is click from the speaker cone, that means the speaker is Ok, and you might need to trouble shoot your stereo to be sure if the sound IC chip is Ok in the stereo..

Hope it helped..

I have an Onkyo AV Receiver HT-R500 and when I turn it on, it turns on and in less than one second it turns back to standby. What could be wrong?.


Try disconnecting all the speakers and see if it does the same thing. If it doesn't, connect speakers again one at a time to find out which one of them is doing it. Make sure the speakers rating match the output of the amp.

Speakers work at low volume. Around -39 db, receiver shuts off.(protection mode) Tried moving speaker wires, alternating red and black. No go. When powered back up, display says ck sp wires. Once I...


Decibels correspond to the output voltage being sent to the speakers. In your case, the voltage is reached at -40dB is the threshold that causes whatever is happening to operate the receiver's protection circuit. You might have a bad speaker, with a voice coil that shorts at the higher voltage. Below that level it's okay, but at the magic point the insulation breaks down, and that's when the receiver sees trouble.

You might try connecting only one speaker at a time using a short length of wire other than your current ones. If the trouble occurs on one speaker only, you've found the culprit. If the receiver operates normally on each speaker, try reconnecting one speaker at a time to determine if one of the speaker wires may have a short somewhere. There might be a weak spot in the insulation, not causing any trouble until the voltage is high enough.

If the receiver still goes into protection with just one speaker, there's an internal problem. Some part in the amplifier may be breaking down at that voltage. Or a part value has changed, causing the protection circuit to kick in even though there's really nothing wrong. Bad solder connections may have developed. Unfortunately, this kind of problem usually needs the services of a shop with the equipment and circuit information to figure out what's happening. If you can find a Yamaha-authorized warranty servicer, they might already know some typical causes if they've seen units with the same trouble.

Try the speaker test first. Then let a shop tackle the receiver if it looks like that's where the fault is. Good luck and thanks for using Fixya!

Ccr1cd keeps turning off my yamaha receiver rx-v480 keeps turning off when i turn it on


check your speakers cables, connections. check for possible cable short. If seem ok, remove all speakers, turn the unit on and see if still turning off. if it does then you have a trouble in your power amplifier, defective output sectiuon. could be your power and driver transistors. possible dirty or corroded system control board. try cleaning.

This worked for me, but I'm sure tired of constantly searching for ways to fix the problems I encounter with my Denon DRA-397. When it works, it's great, but I don't have a degree in electrical engineering. Why can't they produce a user friendly trouble shooting guide?
