My thoughts on the Sony. Older digital tv's tuners are not as good at selecting and locking in on digital channels. The main reason is multipath (reflected signals) bouncing off of things in the attic or buildings , trees , mountains , ect. the older digital tuners are not as good as newer tuners at filtering out multipath. When the antenna is turned to a different direction the main signal can become stronger and the reflected signals are weaker because the antenna is turned away from the strong multipath. Tv antennas like elbow room with nothing crowding in the 'view' of the transmitting antennas. Yes I know the Tv is not that old , it looks like the manufacture date is 2007/2008. A tag/sticker on back of the Sony should have manufacture date. And also it can be a defective tuner/tuning circuits. Also grounding the coax lead in with a coax grounding block to electric service ground can help clear up the signal. The foil shield and shield wires of the coax pick up unwanted signals and the (center wire - the signal carrying wire) receives the unwanted signals from the foil shield and shield wires. A coax grounding block will direct the unwanted signals to ground.
