What causes poor signal quality on TV?
In case video and/or audio is disturbed or no video/audio is present at all, one of the possible reasons is a weak broadcast signal typically due to a bad or broken antenna cable, bad position of satellite dish or interference by other devices.
Why does my TV picture keep breaking up?
If your TV picture is breaking up, cutting in and out, or pixelating (looks like everything is a bunch of squares), then you probably are experiencing a weak signal. Check all of the connections from the wall to your cable box and from the cable box to your TV to ensure that all connections are tight.
How can I get better reception on my digital TV?
Here are some tips for boosting a digital TV signal:
- Move the antenna to new location or height, if you’re using an indoor antenna.
- Re-aim the antenna, if you’re using an outdoor antenna.
- Watch the signal strength meter on the digital-to-analog converter box or television as you move or aim the antenna.
What interferes with digital TV?
Many household appliances like a blender, electric heater, popcorn maker, electric blanket, and refrigerators can also cause interference. Any appliance with electric motors like a ceiling fan can disrupt an over the air TV signal. In some cases, light dimmers have been known to cause issues due to poor wiring.
What does it mean when your TV says digital channel signal strength is low?
Usually it means your TV is set to its OFF AIR ANTENNA input instead of the connection for your DirecTV DVR/Receiver. Check your TV’s Video INPUT or SOURCE selection.
What is the difference between TV signal strength and signal quality?
Signal strength is how strong the signal is that you are receiving. The signal level will drop further away and you will need a larger more powerful aerial or dish. Quality. Quality is how much interference there is between the satellite and your decoder.

Do trees interfere with digital TV antenna?

Why is my TV reception so bad?
Naturally, the farther away from the TV tower you are, the weaker the signal will be. If you live in a valley, a depression, next to a cliff or are surrounded by taller buildings, your reception will be hampered, as electromagnetic waves are bounced or absorbed by these natural and man-made features.
