However the plasma gas trapped in each pixel escapes slowly, and wears out. When this happens, and it will happen, you pick up your tv and throw it in the trash. In addition plasma tv's are brightest when you first buy them, and wear down with age. The wear down is pretty linear with age.
The new plasmas have a lifespan of approximately 100 000 hours, which equals eleven and a half years of 24 hours/day viewing. I think I might have switched TVs by then.
