What smart TVs to stay away from?

Smart TVs to stay away from include very cheap off-brands with poor reliability and no software support, such as no-name Amazon brands like Supersonic, Sceptre low-end models with poor processing, and some early Hisense models with software bugs, plus any TV without major streaming app support. Off-brand TVs sold on Amazon under names like Westinghouse budget models, Insignia low-end, and other unbranded 4K TVs under 300 dollars often have poor build quality, low-quality panels with bad viewing angles, weak processors causing slow smart interface, lack of HDR brightness, and high failure rates for power boards and backlights, with limited warranty and no firmware updates, leading to apps like Netflix and YouTube stopping working after 1 to 2 years. Hisense earlier models from 2018 to 2020 had higher rates of software bugs and backlight failures according to Consumer Reports, though newer Hisense U7 and U8 series have improved significantly. Also avoid TVs with outdated smart platforms like older Opera TV or custom Linux without app store, as they lose support. Avoid buying used plasma TVs with burn-in risk, and avoid extremely large cheap TVs over 75 inches from budget brands as they have higher failure rates. So stay away from no-name Amazon off-brands under 300 dollars, very cheap Sceptre and Supersonic, and any TV lacking Roku, Google TV, or Fire TV platform with poor app support, as they have more problems, short lifespan of 3 to 5 years, and poor picture quality.
