I've posted the procedure for adding a part that will firmly ground the LCD mounting frame, resulting in dramatically lower background noise for those of you experiencing this phenomenon. The part required for this procedure is not yet in our hands, but we do expect to have them within a couple of weeks. These parts will be provided to you at no charge.
The video shows how to install the factory-supplied part to ground the LCD's metal frame to the main chassis. In addition to this process, a firmware update will be issued that further addresses this. We understand that some people do not want to wait for this part. In that case, we have made another video showing how to use aluminum foil to craft a similar part. However, we do recommend that if you use that method, you get the actual part when it becomes available and replace the foil with the part.

Performing either of these procedures will not void your warranty.
