Is LCD better than crt?
You need to be more specific about the criteria to be used in the comparison, but energy wise the lcd uses less power than a crt and that is good for the planet. LCD televisions also take up less space. Although an LCD costs less energy to run, their production processes use more energy than the production of CRT televisions, which may make an LCD more costly in energy, depending on the life of the TV. LCD televisions are starting to incorporate LED backlights, with have the advantage of allowing individual areas to be switched on and off. This enhances contrast (including deep blacks) and picture quality. Picture motion 'smoothness' remains a key advantage of CRT, as the images can "scan" across the screen rather than being limited to jumping between pixels. For optimum picture quality, a HD CRT TV with HDMI input (not upscaling) is better if you can live with the bigger size and higher running cost. A CRT produces a better picture then a LCD. Color standards were set for film and television years ago. As of 05-25-2009 LCD's still can not meet or surpass this standard. 'Deep black' a standard set years ago for film and television is the ability of film and television 'CRT' to show shades of color and gray all the way to complete deep black. An LCD can not meet or surpass this standard. An Lcd can show colors in a Bright kind of way , I call this LCD 'Eye Candy' , it is not true colors and deep black. All this is researchable on the net. And No a plasma screen can not meet or surpass the standard of film and television CRT.

Can i lay a large CRT TV on its front?
It won't hurt the CRT as long as you don't severly jar or shake it in the process. Repair shops used to lay the smaller CTR portable TVs on their front to access the bottom of circuit boards for repair and many shops installed replacement CRTs with the set laying face down. Be careful with CRTs because they can be dangerous if they break.
Why are tube TVs still manufactured?
In poorer 3rd world countries such as those in many parts of Africa, most people cannot afford the price of a new LCD or LED 3D TV. There is still some demand from developing countries for CRT-type TVs as it is one of the first luxury items they will buy with any extra money. Nevertheless, CRT TVs are expected to decline to less than 5% of all households in developing nations by 2015.
