They're all expensive to operate. Today's LCD and DLP sets use a projection lamp that draws on the average of 120 watts to light, plus there are several fans that operate in all three types, not to mention all the support electronics. In general, you can expect them to use more energy than a CRT model. It also depends on how much TV you watch.

Another expense to consider is the additional air conditioner usage to compensate for the heat coming off the projection lamp type sets, unless

you drop the money for a LCD set that uses backlighting by flourescent tubes.

As you can gather, I'm not a big fan of today's TV models for more reasons that I can discuss here. Personally, I'm waiting for the next generation or two before making a commitment to buy a new TV. In the meanwhile, I'm sticking with my CRT TV until I absolutely have to replace it.

On February 17, 2009, all off air signals are supposed to be digital. What that means is that you'll have to have a set top box to convert the TV signals back to the analog type unless you already have a cable box or satellite system to do the conversion for you.

TV manufacturers are working to replace the projection lamp systems, but I personally want to wait to see if they're going to be more dependable than what's on the market today.
