Samsung flat screen TV’s

My b.i.l. lost a Samsung within a year - lines on the display.  My 2 have been fine 5+ years.. My first in '08 was a Sharp - when I updated the firmware it would not start. They told me to go scratch.
My replacement Sony and it's 4K partner have been flawless with lifetime t/s last time I called them (years ago.)  Since 2010. All they've ever needed was a rare reboot

The answer is to get your TV professionally calibrated after you buy it. That way the TV does not have to struggle to produce a great picture. All TV’s in shops have their colour and brightness boosted. There is no way you should use these settings because they can cause burn-out too soon.

I didn't take the time to read all the post's / reply's ..  YET, All TV's Change so much so Quick with technology as you know.. and Yes Samsung has issues with many/some/several, yet I buy Many, for myself and a few customers.. as in maybe 15 in the past year..  The model numbers are critical and I'm staying with Samsung since I can't keep up with Sony and All the Others.. Too.  Actually just got a Samsung 75" Q80T, last years model, -- too much to keep filling this up, yet pick a brand and then Research the heck out of Each Model Number and then make your decesion/s..

Oh, I just saw dyson2004's comment on Calibration.. YES!  Get the BluRay Cisney Calibration DVD!  way cheap now and use it on All your TV's.. Makes a Huge Difference, yet You Must have the patience and take the time to do..
