Possible Causes & Solutions
Weak signal from your aerial.
Check your signal by pressing HOME and selecting Information. If it’s weak or not present, get a professional to check your installation – your aerial may provide a better signal if it is realigned or moved somewhere else. We don’t recommend using an indoor aerial. As a last resort, try using a signal amplifier or booster to improve reception.
Some TV aerials installed with a signal amplifier need a power supply from the TV box.
Activate the T4‑R’s +5V DC supply by going to: Settings > System > 5V Antenna Power.
