Personally will not be buying a Samsung tv again. - Shockingly short serviceable life, and no goodwill.
I bought (what was a flagship model) 65" 8K QLED in March 2021.
It stopped working completely 3 years later. Samsung recommended I send to their authorised service partner (Martin Dawes) who charged me over £90 to investigate. The conclusion of the investigation was "Samsung no longer supply parts for this model".
From my perspective they did not need to charge me £90 to tell me that they cannot get parts for this TV.
....but they are keeping the cash anyway (despite my asking very nicely for a refund).
