When something is faulty and their diagnosis is "The fuse failed" very common in the UK as we have fused plugs.
No the fuse didn't fail, it did it's job. Then they decide to put a bigger fuse in and if that fails a bigger one or a roofing nail.
Whenever something fails dead most people assume "it's just the switch". Also I remember in the CRT era any time a TV failed completely it was always "the tube blew", but when the tube had actually failed and gone dim/blurry "it just needs adjusting".
Back when one of my duties at a TV Studio was repairing picture monitors, I also had to fix quite a few domestic TVs which the "suits" had in their offices.
Many came in with "broken on/off switches", &, indeed, the switches were broken.
On replacing them, the real fault presented itself------a faulty SMPS.
A common fault with many TV power supplies was that the "start" circuit had failed.
Just pressing the new switch didn't start the supply, but the "suits" had discovered that by pushing the switch multiple times in quick succession, you could often "jag" a start.
Of course, this wore out the switch in double quick time!
Fixing the start circuit (in Sanyos, the fault was a 220k resistor which chronically went high or O/C), restored normal operation.
On the same subject, not a peeve, but a funny story regarding such sets, was a 27" Philips in the office of "Norm" ( a really nice bloke).
His TV resided on a large wall shelf, sharing it with a very leafy indoor plant.
It was hired, as were all the other such plants, & a staff member of the hire company, regularly attended to prune it.
In their wisdom, Philips made the power cord a nice browny beige colour, similar to the plant stems.
Inevitably, someone had tidied the cord, so it was lost amongst the foliage.
Along came the hire company gardener, snipping away happily with his pruning shears.
Bang!----A blinding flash, & a very shaken gardener.
Yep he'd mistaken the power cord & snipped it -------just as well his shears had plastic handles, although I doubt insulation rating was at the fore of the manufacturer's thinking!
I said a "funny" story, but it could have been far from funny!
