Strength is not the whole story

A television can show high strength while quality still drops. Quality usually matters more for a stable picture because it reflects how cleanly the tuner can read the broadcast.

Too much signal can also break reception

Boosters are useful in the right place, but an over-amplified signal can overload equipment and create symptoms that look like weak reception.

Read symptoms by multiplex

When only a group of channels fails, the issue may be transmitter, aerial alignment, cable loss, or local interference rather than the television itself.

Before you buy or book anything

  • Record which rooms and devices are affected.
  • Test with one known-good cable or one known-good location.
  • Keep affiliate buying decisions separate from basic troubleshooting.
