In Reply to: Re: Plasma Life Span?? posted by Kal Rubinson on October 26, 2005 at 12:15:41:
Typical plasma TVs have a life span of 20,000 to 30,000 hours, which equates to at about 20 years of usage if you have the set on for 4 hours a day. The lifespan of an LCD TV is typically 50,000 to 60,000 hours, or about 40 years running 4 hours daily. According to Ecoustics site.

Millen, that's not the case and hasn't been for couple of years now.
Manufacturers have worked dilegently on phosphor decay rates since lower-life plasmas first hit the shelves. They've made great strides and now virtually every major plasma manufacturer rates their display at 60,000 hours (or more) to half life. (Based on the same type of reliable phosphor decay rate testing as used for CRTs).That's about 27 years at 6 hours a day. The life-span issue is a non-issue these days.
The new displays are much more resistant to burn-in. I've inhabited the AVS Plasma forum for years, with thousands of plasma owners passing through, and there are no reports of burn-in from average users. (One guy bought a plasma for his kids, who did nothing but "game" on it for about 9 months, and he could spot a tiny bit of burn in on an all-white screen, but not in normal use).
Here is a link to a new study that tested out various "Plasma myths."
It's educational:http://www.pioneerelectronics.com/pio/pe/images/portal/cit_3424/273087528Pioneer DTV White Paper - FINAL.pdf

that's longer than the technology will be valid or of interest.Kal
Should I even bother going with plasma? They seem to have the best pictures of the flat panels, but almost every person I have spoke to about the subject tells me to stay away from plasma sets. Why? Any tv will eventually break down.
early plasma sets failed because the owners and installers had them fitted into the walls like a picture. Heat kills the the plasmas. Current sets have fans and are recommended to be mounted with 2 to 3 inch clearance on all dimensions. There are little problems if the concerns regarding cooling are followed.

However, the biggest culprit is Plasma TVs can suffer from Burn-in or Stuck Pixels burn-in produced by static images. After extended periods, stationary images "burn in" and produce an after-image ghost which remains permanently on the screen. With technologies such as 'pixel orbitor,' new plasma TVs have addressed burn-in and significantly reduced the issues of older models.In addition, LCD TVs do not suffer from burn-in, but can have a "retained pixel charge" which may also produce ghosting. Stuck pixels are also possible with an LCD display. With the latest plasma technology this would be even. The "pixel orbitor" is automatic and does not require additional efforts by the end-user.
neat but not as automatic as it should be. My PDP had it as an option but the factory default is OFF.Kal
I bought one last year and I am very happy I did. Picture is spectacular.Kal
