It’s a throw-away age.
Mum’s bedroom TV (23.6 inch LED) Had been playing up: showed a screensaver when turned on, it could take any time between immediately of 40 minutes before the screensaver would make way for an actual video signal, you couldn’t even select the manual buttond on the rear of the unit, only the power button worked & then not always.
There are two TV retailers in the next town down the highway. There are five in this outer-eastern suburb. But for all that, the cheapest was one of the two stores near Mum. So the fix for the TV problem was to replace it.
