I had the sort of phone call that I dread from my mum earlier this evening...
"We've got a problem with the TV"
She and my stepfather are a pair of technology numpties - no computers, basic mobiles for emergency use only, etc - so when ever they get a new piece of electronic equipment it's a case of set it up and hope they don't fiddle with the controls. From what was described (no TV, radio channels only), one of them may have selected retune and scan for the old analogue channels only. I'll find out tomorrow afternoon.
My opening gambit was to remind them that Currys opens in the morning and they can get a new one which didn't go down too well.
