Basically, the above. We've taken over an old analog distribution system, and recently replaced an old Fujitsu plasma w/ a large Samsung LED unit. No problem while on component distribution.
We were then asked to connect 'His Cable' to the new TV via HDMI as the lead-in to a DM system. Pulled 2x Cat6 about 60' and used a Vanco balun to accomplish this.
We now have a ground loop on component signals (additional cable boxes, BD, AppleTV gen1) to the Samsung. No issue on the other TVs.
Disconnecting the HDMI from the cable box fixes the issue. Other cable boxes/BD also reintroduce the loop. Have tried an isolator on the component connections between the TV and the PVID, and the PVID and the cable box, no change.
Any suggestions/fixes?
