front right speaker no sound

[stumben32]

bit of a newbie at least when it comes to troubleshooting home theaters.

Anyway to start I have a 5.1 set up with polk audio speakers and a pioneer elite reciever.

about a month ago, My front right speaker suddenly stopped working and had a small quiet popping sound when I first turn on.

I did what seemed logical-I switched speakers to rule out bad speaker. same problem with them switched ( front right channel bad ).

I then really made sure the wires were situated good- then BINGO it worked....for about 2 weeks.

now suddenly- the problem is back. I cut back the connecting ends to expose fresh wire....no luck.

thoughts? do I Now try to replace the whole wire? seems odd the wire (2-3 yrs old) would be the problem but what do I know.

that would be the cheapest solution / testing method. If it happens again, sounds like it may be the connection on the receiver shorting out.

You stated, "I switched speakers to rule out bad speaker. same problem with them switched (front right channel bad)." How did you do the switching? Did you use the same wire with a different speaker and the same channel? If so, I would recommend testing the front right channel with a different speaker AND a different wire. You can just switch the wires on the back of the receiver rather than disconnecting them from the speakers. If the problem still remains with the front right channel and not with the front right speaker and wire, then I would assume that the receiver is the problem.

I have this problem with my Klipsch Promedia computer speakers (certain channels randomly cut out but will often work for weeks with no problems). The source of the problem is well-documented as being the volume POT, and hopefully just cleaning them with contact cleaner will fix the problem. I'm not sure if this is applicable to your situation at all, but I figured I'd throw it there.

If not the wire, it sounds like something is bad in the speaker - either a bad solder joint on the crossover board or a detached wire (fuse?). Some manufacturers use polyswitches in speakers (although usually for the tweeter) - if it has one, it could've failed, although I have yet to see one fail.

How could it be a bad speaker when the OP switched the speakers, the other speaker had the same problem. (I.e. it only happened in the right channel, regardless of speaker).

I guess both could be bad, but then why when only connected to the right channel?

It looks like he switched speakers last time the problem occurred, but maybe not this time?

We need more info about what you tried this time the problem occurred to know where the problem is.

Could be that you blew a right channel fuse in your receiver...
