In the not so
distant past, it was not unusual to have a hard
time hearing the volume of a plasma TV over the
buzzing of the units cooling fans at work. These
cooling fans were functioning regularly as the
obsolete plasma TV could produce heat hot enough
to cook eggs. It is no wonder that most of the
early model plasma TV have already retired.
Many different technologies have been at work to
create improvements in today's technology. These
innovations have brought the life spam of a
plasma TV to be calculated at 20 to 25 years for
normal viewing patterns.
Normally a plasma TV has a half-life between
30,000 to 60,000 hours, meaning that the unit
will loose around fifty percent of its
brightness during this time of service. For
instance if a plasma TV was left on for eight
hours a day the expected half life would range
about 9 years. If however the plasma TV were
left on for only 4 hours daily, then its half
life expectancy would range near about eighteen
years.
When considering the loss of brightness in TV
screens the fact that a traditional TV looses
approximately thirty percent of brightness after
use of about 20,000 hours. This loss of light is
so gradual that a viewer may not be aware of the
effect other than to occasionally fine-tune the
levels of brightness and contrast options to
make up the difference.
When a plasma TV looses its light to dimness,
various models present the option of replacing
the light source, thereby renewing the unit's
.life span
Plasma TV life span extension tips.
1. Use wide screen formatting as often as
possible. The use of wide screen viewing insures
that all pixels have opportunity to work.
2. Brightness levels need to set as low as
possible for viewing pleasure. Using the higher
brightness levels strains the pixels and
phosphors, which decreases the plasma TV's life
span.
3. Always, take care that the plasma TV is in a
well-ventilated area. Keeping the unit cool cuts
down on the energy it takes for cooling,
reducing the need for internal cooling fans and
it also aids the phosphors in longer working
time.
4. Do not let static images sit on the units TV
screen for any length of time. Seven to ten
minutes is about the longest that an image
should be left to sit on a display screen. Image
burn in and ghosting effects will cause the TV
screen to wash out. DVD's should not be left on
pause for more that 20 minutes.
5. When interior light is dim, always use a
lower level of contrast. The use of lower
leveled contrast or picture options will help
extend the life span of a plasma TV. Normal
interior lighting calls for no more than sixty
percent a contrast level.
6. Remember that factory settings are always set
higher for best viewing in a show room. Once at
home, the setting options of contrast and
brightness should be adjusted for home
entertainment viewing. 7. Stay away from off
brand plasma TV units or accessories that are
not manufactured as well built or engineered as
good brand name products. These may be cheaper,
but in the long run, you get what you pay for.
8. When not in use turn your plasma TV off.
9. Keep small children away from a plasma TV.
10. Never, mount a plasma TV from the ceiling
facing down.
