Switching everything off at the wall overnight seemed to fix everything for me too though - touch wood. In retrospect, I imagine this kind of thing was inevitable seeing as my TV hadn't been properly switched off since about 2010. Y'see, the genius designers decided to place the ON/OFF button at the rear of the TV, in the most awkward to reach place ever... So partly because of stupid design - but mostly because of laziness tbh - I normally just put it on standby with the remote instead instead of properly OFF.
I'm not entirely sure of all the inner workings of TVs and Sky boxes, but I imagine that my set and cable must produce a fair amount of vampire voltage per month, just sitting there on standby, checking indefinitely for some kind of signal from a remote. Can't be that great for high voltage things to just sit there holding charge and whatnot for so long. Plus, I reckon I'd be classed as a TV-addict compared to the average dude anyway (well, a "watching movies on a TV" addict) which probably doesn't help.
