Good question. In fact none of the manufacturers break-in the plasma themselves. One reason is that doing this would greatly increase production costs. Imagine hooking up hundreds of plasmas and running break in images 24x7 for those 100-200 hours. That would be one hell of an electricity bill (which the company would conveniently pass on to the consumer).
Also what you need to realize is that this "break-in" process is a grey area. For every ten people who swear by it, there will be at least one person who will say that it is a myth and does not need to be done. If you go by logic it makes sense to run these slides so that the gases are worn out evenly. In any case the manufacturer will never say that break-in is a must because doing so would necessitate them to provide the break-in images themselves. And unlike you or I who can just download these images for free from off the net the company would have to come up with their own patented images or pay the guy who came up with these images.... all adding to the cost.
True. Cant agree more with you.
Update on the Dead Pixel :- Samsung guy paid a visit to my home to take a look at the issue. Showed him the dead pixel and image retention issue and he decided that this set needs to replaced with a new one. He said that a new TV will be issued in about a week's time. One more round of calling the installation guy, inspection, experimenting and more break in slides.
