Samsung flat screen TV’s

Had a 75" Samsung 1080p (2/2014) from Costco that a couple of strips of LEDs went out after about 4 years.  I had the extended warranty with a year left.  They sent me a new one but wouldn't let me upgrade.  So the new one has been running for about 3 years with no problems.
I also have a 65" Samsung 4K curved screen (2/2015) from Costco that doesn't get as much use, but still doing OK.  Every once in a while I have to unplug it for a few minutes to reboot it when it glitches and the remote doesn't work.

Started off with a 50" Samsung plasma in 2007.  Still working fine but started showing a reddish burn-in during really dark scenes about 3 years ago.  Moved it to the bedroom and replaced it with a 55" LG OLED about a year ago.  The LG has a superb picture, but a very weird remote and some very odd function logic quirks.  Still, an excellent TV.

The 2004 27" Toshiba SD flat-screen CRT that was in the bedroom is still going strong, as is the 1989 21" Sony Trinitron it replaced.  The Sony's tuner finally went bad, but the CRT works just fine with and external DTV converter into the auxiliary input.  Picture quality on both is excellent for SD TVs.

cd318,  I know that sounds like a lot of work, but I was lucky to find a forum where people discussed such details.  I can see having a professional calibrate a new set, but when I found recommendations for calibration for my model, I thought, “This is something I can do.”  It is a bit time-consuming and slightly tedious, but I only had to do it once.  After calibrating my new set, I looked for suggestions for calibrating my old 42” and that did help.  I noticed that the old set isn’t as bright, no matter how I adjusted brightness, contrast and color saturation, but it is definitely still watchable.  

So far so good with my 60 inch Panasonic plasma. No burn in or other issues. It's on a lot too! Seven years old and going strong. Joe

my 10 year old samsung lcd still works fine, tho i had to replace some failed capacitators right after the one-year warranty expired (a widespread problem which apparently triggered a class action). my lg tvs, otoh, have been flawless. fwiw, a couple of salesmen at abt recently told me that sony is the best-built and that samsung has historically been problematic but is much improved in recent years.
