My Frame TV developed a dim strip in the centre of the screen after four years of ownership.
Samsung would only proceed with organising a repair if I updated the firmware to the latest version. Something I deliberately held back on to avoid the introduction of ads.
Now I have new firmware. And new ads.
Oy for Samsung to tell me that spares are no longer available for my four year old TV, and would I like to buy a new one (with more ads).
Now everywhere I look I see Samsung displays being used in residential and commercial settings, and I'd estimate 30% of them have noticeably inconsistent backlights, with bright or dark spots.
Never again.
I've also noticed a lot of early degradation on edge lit Samsung TVs. Their TVs with backlight zones seem to fair much better.
