Horizontal and vertical oscillators are what blow. If they are run outside
their design range their heat dissipation gets very high. High heat
dissipation means hot parts. Hot parts die out much faster than cool parts.
With semiconductors this is especially true. I've also found that operating
on the edges of the manufacturer's supposedly safe range is another way to
shorten the life span of a monitor. It gets hotter. That means shorter life
span. Every 10 degrees Celsius makes a huge exponential difference.
