My current Sharp 40" standard model lasted me 8 years too, that I did not buy extended because it cost just RM888 when I bought, many ppl consider this miracle.

But this mini LED is close to 6k and they said TV panel have problem easily within 5 years.

This current model is 2023 model, so don't have any history to benchmark how long it can last since TV industry itself life cycle pretty short.
