My Grandparents in Stony Stratford/Milton Keynes (Not sure on Post Code, sorry!) also report loss of main channels, such as BBC series channels. Haven't been over to check for potential "user error", but apparently zero signal outta nowhere.

Lost service for 5+ hours yesterday afternoon/evening on BBC1,2,3,4, ITV1,2 Channel4, 4+1 and Channel5 channels. Gradually came back after retuning box several times. This morning (and still continuing) am losing BBC1. I'm tuned into Sandy Heath transmitter which reports no issues! How come??

For Inf.
I have just phoned a very helpful person @ Freeview helpline 08456505050 " Ian "
Who checked with me my signal strengths on various channels, and the quality. ( All via my menu, and then the installation & manual. They are all good strength & rubbish quality. Due to high pressure area. He says DO NOT re-tune, or you will lose channels. Must wait till pressure reduces & moves. Then we should get all them back.
Hurrah, a sensible answer!

Last few months loosing signal. Been through all the reset procedures and replaced an old signal booster with brand new one. Spoke to Digital and 4G people and both said nothing wrong. I see on your map that in the sea of green for MK that my village is all white.
What should I do next, it used to be fine 3 months ago ish. Many thanks

TV keeps going off, breaking up on BBC1 and some other channels always when you want to watch something special it does this. It says Freeview signal poor quality or too low level. Very frustrating when we pay so much for TV. What the hell is going on?
