Close to 10 years old ie. 2011 59 inch plasma - was Samsung's flagship back in the day - and it is still going great.
So great in fact I simply cant justify getting get rid of it and UG to a modern 4k option.
Early Philips 32" LCD TV (HD ready!) from around 2005 still going strong. Very dumb, huge bezels and ways a tonne for an LCD TV of that size. In daily use for TV, Netflix and watching the odd DVD. Was expensive at the time being 2nd or 3rd generation LCD TVs.
Sometimes an issue with turning it on since a few years, needs an extra on and off before it works at times. Can live with that.
It replaced a 70s CRT tube which was even heavier and died somewhere around 2009 then still serving as second TV in bedroom.
So this LCD needs to last at least another 10 years :-)
Panasonic TH-42PV8AZ, mfg date of Aug 2008, purchased Nov 2008
Still the main TV, even though it's only a 720 panel.
Going strong, no fading, lines or anything. 335W of room-warming.
I see a 55 or 65" OLED in the near-ish future. Gotta keep off the smokes for a while yet ....
Then it will be relegated to the garage ...
