It is been believed that the plasma televisions are more affordable and do not have a long life as that of the normal televisions. But the scenario has been changed now because some manufacturers have guaranteed their products for a life span of about 60,000 hours of viewing time; it is nearly about twenty seven years in most homes.
There is also an interesting story about the plasma television, like when an image is kept on the screen for a long time it gets permanently burned on to the screen. For example if a game image is kept for a long time it gets burned to the screen permanently. A ghost like image is seen after that. This is true to some extent, but after several improvements it was discovered that the image would disappear later when a moving image was projected on to the screen.
The plasma television has several inputs to be enabled to connect with the DVD, video, computer, etc. In normal television, the worse case is scrabbling around pulling cables in and out of the screen. This has been completely inbuilt in plasma televisions. So, the price goes affordable for all our needs.
The quality of sound is great and many sets come with standard speakers or clip-on extras. But still some people prefer to connect the sound through their own high quality music systems. It is the same as these plasma screens costs as much as a second-hand car. A great care has to be taken to choose the right one to get the fullest entertainment.
