I bought my mum a 55 inch Samsung the Frame for her bedroom.
After 3 years it start having some thin horizontal line.
And I have to say her usage is very minimal, maybe 10-20 hours a week max.

While in the main hall I'm using Sony 65x7000f that I got in 2019, still alive and kicking after years of daily abuse from me and my dad.
This is a very basic entry tv that doesn't even have Android/Google TV.
I remember checking the screen usage last year, it was already over 20,000 hours.
Sometime I really hope this tv 'die' so I can replace it with a 120hz panel mini LED tv (for my PS5 Pro) LOL

Anyway what I believe is ...... it's all down to luck.

My cousin had a LG OLED (can't recall which model), within 2 years panel issue.
Luckily it was under warranty so the technician replaced the panel for free.

My previous Sony TV was 50W800B, it lasted for 3.5-4 years then panel kaput.

If I'm in the market for a new TV right now, I'm leaning slightly towards TCL new mini LED tv.
The only thing that haven't convince me entirely is their service.
