A replacement tube (if it is available) is likely going to cost almost as much as the whole television. If you need a new tube, it's time to ditch the tube TV and get a flat screen.
Over $2200. dollars.
The problem you describe might be the tube, but there are other parts of the television that can cause similar effects. You will need to have it checked at a TV repair center and they will also be able to tell you how much a new tube could cost. In these days of very low cost televisions, it is quite likely that the tube will cost more than a new television.
Usually less than $100

The old school box projection tv need three picture tubes ranging around $200 a piece. Cheaper to buy a new tv.
This varied widely with the type of tube. Many common radio tubes cost less than 25 cents. A picture tube for a TV might be $50 to $100 depending on size. High power transmitting tubes could cost thousands of dollars.
Those were picture-tube TVs. The picture tube was almost as long as the TV screen was wide.

Truthfully, at best you'd only be able to get a rebuilt and then you'd better be prepared to shell out more than the TV originally cost for the new tube. Better off getting another TV.
It shouldn't. If there is no actual power to the CRT (no picture visible) then there really can't be any degradation of the tube.
In the old days of CRT televisions, I would have rated Sony TVs at the top. Their Trinitron picture tube was (in my opinion) the best picture tube made. But now, in the era of flat-screen TVs, the relative merits of the various makes are less significant. I bought a "bottom of the line" TV from Best Buy because it had all of the features I needed, and didn't cost me a fortune.
A lot of people consider LG to be the standard for plasma televisions. They have a very clear picture due to their TruBlack Filter and Protective Skin Glass System.
