In Reply to: why be plasma-phobic? by jcosler
Ever wrestled with a 36 inch CRT TV? Takes at least two gorillas. Now, the first sets were the plasma type and growing pains abounded. LCD sets quickly followed and LED soon thereafter. Each in succession lighter for their size and more fragile. Plasma sets have heat as a by product of the 60 volt power supply for the "glow" potential and that heat is also present on the tube(s) themselves. Burn in can be achieved by those intent on doing so, otherwise not a factor for present sets. LCD sets are not subject to burn in, more likely to get a stuck pixel. Plasma units will exhibit unique failures that have started with a single pixel, not noticable at first, but it multiplies and grows into bigger and bigger blocks. Some early units that had inadequate ventilation and were getting hot enough to melt the flexible trace ribbon cables. Not acceeptable, who ever heard of a fan on TV, of any kind. Maybe a projector needs it, loads of heat there. Environments and ON times(duty cycle) play the biggest part, regardless of the mfgr or type in determining the "LIFE" of a TV.
