Hi,
I would think that the tube has blown with the things you described if you have a standard TV (not LCD/Plasma).
If you have no knowledge of TV/electrical engineering I would strongly suggest you do not remove the back of the TV as there is a risk of electic shock if you don't know what your messing with.
Use your Yellow pages etc to contact a tv engineer, they'll probably tell you that a replacement TV is cheaper than repair these days.
Hope this helps
