For sure, inside the warranty period, but even after that. Most TV warranties are for 1 to 3 years. My LG OLED TV is 2 years old. The other 4 TVs in this house from Samsung, Vizio, and Seiko are all at least 5 years old. My Samsung microwave oven, used daily is at least 10 years old. My coffee pot is probably 8. The powered Logitech surround sound speaker system on this computer is at least 15 years old.
As I noted earlier, I've been maintaining and repairing electronic equipment for many years - not as a hobby, but as my job. It is not an opinion, it is just a fact. Back in the day with vacuum tubes and discrete analog components, electronics broke down a lot more often. TV repairmen made house calls! They would come in with one or two "tube caddies". Your local grocery and drug stores had tube testers in them. Every town had at least one radio, TV and appliance repair shop.
As the move to discrete solid state devices advanced, reliability improved and that continued to improve as we moved into the digital and integrated circuit age.
When I first started out maintaining Air Force air traffic control facilities, we had ~25 technicians assigned to the shop just to maintain the tower radios and consoles. When all our tube based radios were upgraded to solid state radios, we lost 1/2 our manpower. And that was not just because the radios were much more reliable, but also because we needed fewer backup radios and spares even though we still had the exact same number of UHF and VHF frequencies to cover.
Years ago when IBM, Northgate, Compaq, Dell, Zeos, and Gateway computers were starting out, every computer went through a "burn-in" period before it left the factory. This is because it is not uncommon for new electronics to die upon first power up, or shortly thereafter. That is still true today. But back then it was very expensive for those companies to deal with those warranty returns and repairs. It was cheaper to catch them before they left the factory.
However, as the state-of-the-art, quality of raw materials, design, and manufacturing techniques all improved, the number of brand new electronics that failed in those burn-in periods dropped so dramatically that it no longer became necessary (or cost effective) to test every product as it came off the assembly line.
So again, today's electronics tend to last a very long time, or they get retired and replaced before they die. That's just the facts.
