I told our dealer I couldn't believe in 2008 we were getting a RCA Tube tv with our Sandpiper TT
This situation may well be one of those where differences of opinion will color someones idea of what is right or wrong, but I wouldn't want a CRT television in my RV if I could possibly have a choice. One of the main things that one should ascertain when getting a TV of any kind, is if the TV has a digital tuner. As everyone should know by now, TV as we know it, will change after February 17, 2009 when broadcasters will turn their analog signals off and broadcast only in digital format. This will affect only receivers that are connected to an antenna in order to receive over-the -air signals. Satellite and cable customers can continue to use their old analog sets if they desire. All television receivers sold after February 2007 must include an over-the-air ATSC digital tuner or be clearly labeled saying the sets won’t work after next year’s digital transition. This also applies to VCR's and DVR's with analog tuners. I mention this because there have already been cases where almost all large retailers have broken this law and have been fined by the FCC.
I would make sure that the television receiver that has been sold along with your RV, at least has digial capabilites as required by law. My personal preference would be to ditch the CRT receiver and install an digitally capable LCD if you could afford it.
I'm good with an 'old school' CRT. I picked up a 32" Sony Trinitron for 1/4 the price of an equivalent LCD and don't have nearly the same heat generation. Besides, many cheap LCDs have pixel failure soon after purchase that just annoys the crap out of me.
As I have said above, personal preference will enter into anyone's decision as to which type receiver that you may wish to own. However, your statement that your 32" CRT receiver doesn't have nearly the heat generation of an equavilent LCD, is inaccurate. Unlike standard CRT and Plasma televisions, since there are no phosphors that light up, less power is needed for operation and the light source in an LCD television generates less heat than a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself. Further, LCD's are lighter in weight (when comparing same screen sizes) than their Plasma counterparts and typically require about half the power to operate.
As far as pixel failure is concerned, Plasma sets are actually more prone to have this trouble than LCD's are. Keep in mind, you get what you pay for. There are alot of cheap junk LCDs units available. Cheaper units tend to have very poor picture quality and the warranties are less than acceptable. Obviously, pixel failure, or any other sort of failure would be more likely in the cheaper, no name units. However, pixel failure has not been a problem of any consequence in quality units for quite some time now. Stick to a name brand such as Samsung, Sony, Panosonic, etc., in order to expect the best quality picture along with longevity.
One of the first things I did with my trailer was to remove the cheap LCD monitor that was installed to operate with the Concertone unit, and replace it with a 20" Samsung LCD unit with a built in tuner.
