I think every 5 - 6 years is sufficient, depending on the advances in technology (although considerably longer if you had bought a Kuro back in the day!)
I've currently got a LG 47LW550T (had it since July 2011), currently looking to get either a 55C6V or 55E6V, as I need a TV with 3D...didn't quite have the cash for the C6V the other week when it was available in Richer Sounds unfortunately.
I didn't used to change very often, had a 40" Samsing LCD for a few years which went pop just before we moved into this flat in mid 2013.Since then it's been:
July 2013:Panasonic 42" ST50 Plasma.Got bad image burn so returned and replaced with...
Jan 2014:Panasonic 47" ET60 LED.Awful DSE, sold on eBay and replaced with...
Nov 2014:Samsung 49" H6400 LED.Also very bad DSE, returned to JL and replaced with...
Dec 2014:Samsung 48" HU7500 4K LED.Brilliant TV, moved to my games room and still have it now
March 2016:Samsung 50" JU6800 4K HDR LED.Won this.Didn't like it (DSE as only a 50Hz panel).Gave it to my sister who loves it
Apr 2016:Samsung 49" JS9000 4K Curved LED.Couldn't be bothered to move the HU7500 again so bought this.A mistake, Mrs Lem hated the curve and nagged endlessly.It died - I have no idea if it was inflicted by Mrs L - and was replaced by JL (plus some more money) with...
June 2016:LG 55" B6 OLED.The best TV I have ever owned bar none, and still have it over a year later.We're moving house shortly and this is going in a dedicated home cinema/games room (HU7500 into the summer house/bar).Will probably buy a smaller Sony 43" XE8004 for the lounge then
I recently purchased a 55" LG C6V OLED. I would normally only consider buying when a new "feature" that I particularly want is available. In this case it was the jump to 4K and HDR. However a big part was also the removal of a feature in future TV's. In my case as a big 3D fan getting a 2016 model was important since it seemed like most TV's, if not nearly all, would no longer have this as an option. So it was almost necessity of having to purchase now if I still wanted to watch 3D for at least the next few years whilst maintaining the ability to also get into 4K & HDR content in the future.
Before that I had a 55" Samsung UE55H6400 Smart 3D LED TV. TBH I was perfectly happy with it and had the aforementioned conundrum I found myself in above not presented itself I would have stuck with it for another year or two, probably upgrading once HDMI vers 2.1 devices had been released and had time to come in the next year sale! In fact I was so happy with the Samsung I couldn't bear to be parted with it and so paid for it to be installed at my parent's house for Fathers Day. Made my dad very happy.......my mum....well.....she'll get over it data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7........at some point data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7.......I hope!
Pioneer 5090 followed by the penultimate generation 60" Kuro a few years later. Keep thinking I'll replace it with an OLED, but I struggle to see £4000's worth of added viewing pleasure and am put off by my perception of standards in hdmi and HDR being in a state of flux.
In the same period, I've changed my projector three times.There again, I'll probably sit tight until it dies.I've yet to see laser, but prices would have to come way down.
Only use a TV for watching general programs, otherwise I use a projector all the way. (It’s in the lounge the same as the TV as I don’t have room for a bat cave)
Current TV is about 4 – 5 years old (40” Samsung HD) whereas my previous TV (32” Panasonic CRT) lasted about 10 years. (If it wasn’t for HD I would still be using the Panasonic today)
Most new TVs are incremental updates year on year with only a big update every few years; hence there is no reason to change unless it is a big update. (Will probably not bother with a 4K HDR TV until a reasonably priced 4K HDR Projector comes along, as this always has priority over a TV)

Buying a projector has screwed up the TV dynamic for me.My last 2 TVs were the Kuro LX6090 which I owned for 2 years, which was only replaced as I included it in my house sale at the time, and I replaced it with the Samsung PS59D6900 plasma, which I've now owned for nearly 6 years.
It still provides me with an awesome image (I use a Lumagen scaler with chromapure autocalibration), so I honestly don't feel a need to upgrade.The OLED/4K/UHD itch has been getting at me at different times, but the problem is I have a 1080p DLP projector and scope widescreen setup (8' wide), and nothing can compete with that from a TV perspective.
I love the scale of the image, and buying an OLED TV would be a waste as I want that scale first and foremost...so despite having HDR and more resolution, I'd still rather watch a movie on an 8' screen rather than 60".
So I'm happy to wait it out as long as my plasma continues to work...
My dad has never upgraded...in fact he never bought a tv. To begin with he used his old parents tv, was later donated one by my other grandparents not once but twice..then he used my first tv until I later bought my first lcd (Samsung 40M86 still going today) and now uses my late grandad's old plasma.
In his late parents home where he also visits often he still watches an old square CRT. It buzzes like no other.
No kidding he's coming on 70 and never bought a tv. He doesn't miss an episode of motd or the news though.
Oh and power consumption isn't an issue because he turns off by the plug. Damn those pesky standby lights. Old school.
I won't include all the CRTs I've owned, so I'll start with my first LCD. I got my 32" Sony in 2006 and I only had it for about a year, then I realized it wasn't big enough, so I sold it (with a nice discount) to my brother. data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
So in 2007 I got a 46" Sony which I had until last year (so for almost 9 years), which I then gave to my brother. Anyone noticing a pattern? data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7
And then last year I got my current OLED which I plan to have for a while, definitely more than five years. And my bro said it's too big for him, so I don't know what I'll do with it, once I decide to replace it.
Seems to be every 2-3 years for me too, but I also tend to look at last years models when upgrading for value. This year I went for the UE65KS8000, and got it for nearly half list price. I always loved plasma, and had one since 2002 (Panny TH42PW4), but finally moved away from plasma in 2015 (having had 4!) with a Samsung UE55HU7500 (great set). Even bought the SEK-3500 Evolution Kit for it, which made a big difference. I do a lot of research, and while features and picture quality are really important, every time I've upgraded, I've always gone 'bigger', so screen sizes have gone 42, 47, 50, 51, 55 and now 65. I now say I'll never go bigger, but you never say never! Funny thing is, despite me itching to upgrade the set now and again, my amp and speakers are the same ones I bought in 2009, and I'm still prefectly happy with them.
I have a 55 inch Bush tv that I'm quite happy with as I got it free due to 1 dead pixel on it that you can't even see unless the screen is black. Couldn't complain. Before that I was strictly a projector man but my partner kinda forced me to do the 'normal' thing after we moved in together 2 years ago. We also have tiny tv's in the kitchen and bedroom.
Looking to upgrade to a 65 inch OLED 4K tv next to go with my Nvidia Shield, but I'll never get rid of the projector itch that will need to be scratched one day. The tv also ties into my smart home get up via the Amazon Echo, that includes my entertainment stations and lighting.
