Hi Folks, I have just changed over to TFT monitor which gives good results, except that I have had to stop using my Labtec satellite speakers due to MAINS HUMMMM! I feel sure this is due to an EARTH LOOP. But can't find how to get into the Bass unit to fit filters to the audio cable screens. Has anyone else had this sort of problem?
The Monitors built in speakers are fine but not music quality. Any help would be greatly appreciated.
Proview have been very good, and sent me a replacement power adapter to try but the result is exactly the same.
Thanks for your help, and I have removed the hum but not by a method that I would advocate for anyone else to try. I have disconnected the earth wire in the mains plug to the Labtec Base unit!. I tried to get in touch with Labtec but they don't appear to have an e'mail address for customer support.
I had already checked for ground connections between mains earth and audio feed connectors and didn't find any, then purely by chance decided to see if anything showed up between the mains earth and bass speaker input and much to my surprise found that one side of the input plug was a dead short to mains earth.
I must get in touch with them for an explanation. Tnx, Keith
