Television and Home Theater

TV makes sound as though it is turning on but no picture or sound. Will do this up to 3 times then nothing.

I have a Dell Latitude with an SVideo port and an SVideo to RCA adaptor to the TV. Everything is set up correctly as far as the hardware is concerned - the cable and adaptor work - and the TV is set up to the same setting as our DVD player, but no matter what, we never get what is on the monitor to show up on the TV. We followed the instrustions on the article here entitled "How to connect a computer to your TV set," but still nothing. When I start up the computer, the monitor image shows up for about 5 seconds, then cuts off.

I have a 1992 51'' rear projection TV that was recently given to me. It's a Panasonic model TPT51XF20.
It seems like the blue CRT is almost dead. I was told by the previous owner that the blue color has deteriorated over several months. The picture seems to be reasonably aligned. At any time the background is greenish and people faces are reddish. In any darker scenes, I can't see much at all. The brightness is almost at its maximum. The color selection is also high. If I go in the menu, I can't see the white cursor as I move through the various selections.
