A few evenings ago, turned on the telly to find the picture stuttering and breaking up badly. An hour or two later, it was gone. 'No or bad signal' messages on every channel. Next day, it was back to normal. Until the evening. When it started breaking up badly, then died altogether. Which established a pattern. It's now like this every day. Today I actually took some pictures. At 2 this afternoon, on two of our local transmitters, the signals were like this: Four hours later, having changed absolutely nothing, the same transmitters show as: Googling throws up loads of suggestions along the lines of checking cables & connections, which I've done, but it makes no difference - no great surprise there, since if it was something along those lines, you'd expect it to be consistent all the time. Or it could be interference from a street light - but the break up starts before the street lights come on. Or it could be interference from a microwave oven, LED lighting or something along those lines - but we've changed nothing in the house. And every night it's the same: fine at lunchtime; dead by dinnertime. (Though even stranger, it sometimes comes back, partially or fully, at certain times in the evening. Last weekend's MoTD, eg, was flawless.) It's driving me nuts (and no-one else in the house is exactly hooraying about it). Any ideas gratefully received.
