[Promedia 5.1 Ultra static hiss through satellite speakers]

Thanks Davemd11,

I contacted him and although he is not taking orders for the rest of the year at least I know where I can go in January and in the mean time he gave me a few pointers of certain capacitors and zeners to try to replace.

thanks again

Happy Holdays

[Promedia 5.1 Ultra static hiss through satellite speakers]

Hello everyone and thank you in advance for ANY advice, it is greatly appreciated.

I purchased my unit in August of 2004. About two weeks ago I started to get a static hiss sound through the satellite speakers. I contacted Klipsch for repairs but unfortunately as many of you know they no longer service this unit. Reading on the Klipsch forums I learned that the two 100mFd 35 volt 85°c capacitors on the main board next to a pair of small, black heat sinks often go bad. I replaced these with 100mFd 35 volt 105°c capacitors but this did not eliminate the static hiss I am getting from my satellites.

I did some process of elimination/troubleshooting and here is what I found:

1-It is definitely not my sound card; the static is heard even when disconnected from the sound card

2-The sound in intermittent, sometimes I turn on the unit and hear the static immediately and after some use the static hiss is no longer audible. Other times I can turn it on and hear no static at all but after some use I start to hear the static again. It seems totally random when the static is heard.

3-The static is not audible through head phones plugged into the headphone jack in the controller.

4-The static gets louder when I turn up the volume on the control box.

So from all of this information can anyone give me any ideas or point me in A direction? Luckily I work with a Electrical Engineer who can help me out but since Klipsch doesn't provide the PCB schematics so finding the problem is a bit more difficult.

thank you again for any advise or help
