medyo maiba ng topic, may i know kung gano talga katagal ang buhay ng plasma natin? yung real life na lifespan nya? 3 years? 5 years? How long bago mo masabi na sulit na sya?
ako kasi iniisip ko, parang swerte na to pag umabot ng 3 years.
Hindi naman ganun kaikli sir ang lifespan ng plasma --- otherwise, kawawa naman tayong mga owners.
Will have to agree with sir boybi na mukhang aabot naman at least 20 years lifespan. My unit's a Panny 50pv70.
Well, manufacturers claim na aabot (daw) ng
60,000 hrs ang plasma.
Got these figures from a review:
Panasonic: States in new specifications that new plasma TVs and monitors are good to 60,000 to half life.
Samsung: Lists 60,000 hours for plasma lineup.
Pioneer: States 60,000 hours of use in their 2005 models.
Sharp LCD panels: States 60,000 hour life.
Anyhu, the same review gives tips on how to "take care" of our plasma tvs:
There are steps you can take to ensure longer and better life from your plasma display panel:
1) Never leave static images on the unit. Plasma phosphors have become more resilient to burn in, but still its better to be safe. Do not leave a static image on the plasma screen for more than 7-10 minutes. This can cause a ghosting effect which will "wash" out by use. Watch the unit in full widescreen format as much as possible to avoid differentiation between the side bars of the unit. While this does not actually decrease the longevity of the phosphors it does cause an annoyance to have to play a gray static image to "erase" the temporary burn in.
2) Use Brightness and Contrast levels that are necessary for viewing - not excessive. In a brightly lit room you may need to view the plasma TV at a higher contrast and brightness, which will decrease the life of the unit. However, there are memory setting adjustments available on most recent plasma displays that allow the user to choose a memory setting to suit viewing needs. At night, or in a lower light room use lower contrast levels and extend the life. Do not use your plasma display on 100% contrast (often disguised as the picture option in the menu). In rooms with normal lighting you should not need to use the contrast setting on more than 60% of contrast.
NOTE: Plasma manufacturers routinely ship plasma TVs with the contrast (picture) setting tweaked to 80 to 100% of contrast. Therefore, you will need to make this necessary adjustment yourself.
3) Keep the monitor/TV in a well-ventilated area. The cooling system in the plasma will not have to work as hard.
4) Buy a good brand. First tier brands are typically better built and engineered and will last longer. My first question when someone tells me about a plasma that pooped out on them is, “What brand and model was it?” Most of the time, it’s an “off” brand.
5) Turn the plasma off when not in use.
6) Keep the unit out of reach of small children.
7) Do not mount the unit face down from the ceiling
Hope d foregoing helps.
