Usually when it breaks here in my family with my parents. Which is hardly ever. So the TV turnover rate is actually fairly low. I believe it's been... Hmmm, 5 in total over a few decades in one household, with the most recent one starting now.
First one was stolen from us during break-in burgulary, one replacement until the tube went, then the next one lasted until 2008 when flat screen LCD/LED panels became more common and drew less power overall and had a bigger screen - so that was the only one to divert from how we typically go for TVs, we swapped for efficiency and size of screen this one time. Then it began ghosting, but was random about it, so we were on and off about replacing until it got really bad. Then finally, recently, saw some OLEDs on offer. Snagged one for replacement. And that's it really. The previous LCD/LED screen one may have lasted longer, but it's a known brand that had a well known ghosting issue which otherwise would be in direct service if it wasn't made so badly.
