Promedia 5.1 Ultra issue

[Davemd11]

Hello,

The issue I am having is that I can be listening to some music, watching videos or chatting on Ventrilo with someone and just randomly get a loud electronic noise that sounds like a a tone from holding a button down on a old touch tone phone except very distorted. The sound of it is at least twice as loud as I have the volume set at and does not change with volume adjustment. It lasts for 5-10 seconds and then stops. I usually don't hear it again for maybe another 12-24 hours.



When it does happen, after the noise quits, sometimes my channels will be mixed (center from rear left, front right coming from rear right, etc) other times it just stops and channels remain normal.



There is also a barely perceptive static buzz that I can hear through the speakers and the headphones, and it does not change with volume. The only way to hear it is to put your ear up to the speaker, but is more noticeable with headphones equipped obviously due to a quieter environment.

The buzz doesn't bother me since it is not noticeable while listening to content at anything above speaking volume. The random loud noise is however, intolerable. Hopefully an easy remedy.



I have had this 5.1 Ultra system since they came out, In fact they were replacements for the original THX 5.1 Promedia from Klipsch when I sent those in for repair.



Is this a sign of my wonderful speakers headed for their grave? I've gone through the forum and couldn't find any postings with a similar issue as mine other than buzzing.

Thanks for any input the community may have.

It's should be fixable. Inspect the main board with the big transformer on it for any

signs of stuff that is burnt. It's very common for the the components near the big transformer

to heat up and burn. I have replaced atleast 30 components on my board and it's working

great still.
