Comcast
I wasn't sure where to post this, but I'm experiencing some noise coming through the speakers when the Comcast box is plugged into the HDMI input on the Oppo blu ray player. I need to double check the grounding on the service entrance for the cable line, but I also suspect that the cable box itself is just a noisy source. Actually, now that I remember it, I think the hum remained even if I disconnected the cable input on the Comcast box. Has anyone else had this issue?
Apologies if the topic is covered somewhere in another thread. Thanks, Howard |

Howard.......Many cable and satellite noise issues have been solved with this device.

Howard,
Does the hum vary with volume? Or is it there all the time, at a low level? If you pull the cable feed to the Comcast box and you've still got hum, try putting a common mode choke on the HDMI cable. Tom

The hum doesn't vary with volume, it's there all the time at a low level. I'll give both this and the isolator a try. Thanks!

I had the same problem with Comcast and it was related to different grounds on the cable feed vs. the house electrical, amounting to several volts. I "fixed" it by going to DirectTV satellite. Better resolution, better programming, less expensive. What's not to like?
