Just recently my DVR started pixelating even on recorded TV or regular TV. The interference is from my inferred fireplace that’s been in the same place for five years. It’s a tv stand slash Blu-ray, cable box stereo receiver holder. This just started recently for no apparent reason. Now if I use the fireplace the TV pixelization is horrible. If I turn off the fireplace the pixelating stops. This was never a problem till this winter. I can’t move the DVR away from its current place in the Entertainmnent stand and the fireplace is built into the entertainment stand. What can be done to fix this suddenly new interference that’s happening.
