Images on TV screen have some stop or macroblocks due to signals being too strong

Possible cause: Amplifier sensitivity is at maximum and signals are too strong. Turn the dB dial slowly anti-clockwise until the picture clears up.

No power when trying to use the TV aerial/radio

Possible cause: Blown fuse. Check the 5-amp fuse marked 'radio' inside the PDU hasn't blown.
