Issue: Lines similar to a ground loop are being generated on a LG 70" plasma dispaly due to two RF controlled dimmers in the room.
The grounds were lifted from all equipment and new wiring was tested, yet the issue remained which seems to indicate that the spark noise is being fed onto a wire other than the ground.
Speaking to others, it sounds like it may be noise that is being fed to the neutral, and not the ground.
How do I fix this?
Also: Why is it when HDMI is run instead of component video the problem goes away?
This is part of a high-end installation with cable runs of about 75 feet from the equipment to the display. Running HDMI (or similar) is not a realistic solution as retroing wires in will cost several thousand dollars in faux painting work at least.
Would a UPS bring all grounds and neutrals to a common smooth sine wave free of noise? A couple of these could be relatively easily added to the system.
How about rewiring the electrical?
What would actually put this noise onto the dedicated circuit(s) that are being used for the A/V work?
Any help and insight is appreciated!
