What happens when a plasma TV lifespan hours are finished?

When a plasma TV reaches the end of its lifespan, which is typically around 30,000 to 60,000 hours of use, it may start to show signs of deterioration such as reduced brightness, color fading, or screen burn-in. Eventually, the display may fail entirely, resulting in no picture or sound. At this point, the TV is often considered obsolete, and replacement is usually necessary, as repairs can be costly and impractical.
