I'll agree that a modern TV is unlikely to be economically repairable if it breaks. For the price of calling somebody out to look at it, you could have got a used (or even new) one that's still better than what you had.

Where the good old days you had a local TV repair man, who could fix the few things that went wrong with them. And chances are most TVs then had the exact same faults. It wasn't just a couple of circuit boards they no longer make that cost nearly the same as the whole TV.

My TVs and monitors have always been fairly reliable. Only really had one fail before I wanted to upgrade it anyway, and that was a cheap Samsung monitor that was pushing 15 years old. A £40 used one from CEX was just as good. I don't know if I've just been lucky, but I tend to stay away from the cheapo supermarket brands. If you're buying the Deal of The Week from Aldi, where they get you a 65" TV for under £400 then you might have less luck.
