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.
