I've read a lot of information about ground looping, and a lot of the solutions seem great. One problem I'm noticing is that a lot of the solutions, like using one of these( http://www.partsexpress.com/pe/showdetl.cfm?AID=1457539&PID=440939&Partnumber=180-075+&DID=7 ), might not work with an HDTV or Digital Cable feed.
I have a low frequency hum in my speakers and bands of discoloration travelling up my LCD TV (Samsung LN40A750). I unplugged my subwoofer and there was no change. I unplugged the coax cable going into my cable box and it stopped. This cable comes in from the wall and goes through a splitter, one side goes to a cable model and one side to the cable box. I unplugged the coax going into my modem and the hum was still there. I'm 99% sure the problem lies in the cable box.
I'm only on a digital cable feed, but I'm about to upgrade to the HD TV. What solutions do I have that won't effect this or my internet connection coming in. Also, should I place such an in-line solution like the isolation transformer before or after the splitter?
Thanks for all the help. I checked to see if this specific of a question was already asked but I didn't see anything. If I missed it I'm terribly sorry and you can direct me to any posts that I may have missed.
cheers!
