Static noises coming from subwoofer, please help.

[Slap]

First off, hello all (my first post)

My subwoofer on my Promedia 4.1 system is emitting a strange static

type noise that has been progressively getting worse/louder over time;

the best way I can describe the noise is that it sounds like a constant

grumbling wind that emits static noise(like the crackling of a radio

that is not tuned in) in peaks and troffs, some of the peaks are

extremely noisy, so much so that I cannot use it anymore.

This noise happens whether the speakers are connect to the sub or not.

I noticed that there is a small fuse inside the sub and I am wondering if this could be the culprit?

I have also sent an email direct to Klipsch but 3 days ago for support but I have not yet received a reply.

Any help or advice would be much appreciated, thanks.

Update: I got a reply today from Klipsch saying that I should contact

the authorized dealer of Klipsch products outside the US (I live in

London/UK.) which is http://www.tnsdistribution.com/ for a list of

re-sellers.

No luck so far as they do not have any retailers or support listed for

the Promedia range here in the UK.

So at the moment I am left in the dark on both support, where to

purchase, replace or repair the faulty sub if I need to.

A few questions if you please:

1) Is there technical support on these forums from Klipsch?

2) Is there somewhere in the UK that actually sell the 4.1 Promedia range?

3) Are the 4.1 Promedia range discontinued?

4) What is the warranty on the Promedia 4.1 range?

Can a Klipsch representative of these forums please advise ASAP.

Thank you

I'm also getting subwoofer static starting yesterday after owning the promedia 4.1 for 6 years. I was suspecting the pre-amp could be the culprit. I also opened up the subwoofer and this was what i found.

disassembled

rusted heat transferring material

pretty bad burnt mark on the pcb

Thanks for the posting those pictures fEArmE, it gives me an idea what to look out for.

I will do the same when I get a chance and post back with results.

Would a forum admin or Klipsch representative please help or least respond!

I'm getting the same service via emails (silent treatment) which is giving me cause for concern...

I really need to get this problem resolved Klipsch, please help.

After 6 years or so of use,it can happen to any PC speakers amp section. Good pics BTW,yes the overehating and stress is very visible.

Also these problems can be found on Logitech first sets of high power speaker amps.

seems to be a ton of these on ebay. some new in a box, starting bids very low, buy now very low.

Rust is not an indication of excessive heat. If that was the case, alot of cars would be bursting into flames.

You can say that rust is an indication of poorly protected iron which has been exposed to oxygen...

The purpose of those "heat transferring materials" is not to transfer heat - those are metal clips used to hold the transistor firmly to the heatsink so that the back of the transistor can transfer the heat effectively to the heatsink.

[fEArmE]

yeah... you are right.. those clips are just to assert forces to the transistor.. as i said, those are not the culprit.. but the pre-amp.

I would say clean the 1/8 mini stereo plugs with alcohol and move the wires so there is no crosstalk.
