Tv screen CRT TUBE no image?

Forget it. And be VERY careful with CRT, apart from lethal voltages all over the place, they are vacuum tubes, one careless move and they IMPLODE, concentrating shattered glass which can then be projected with the force of an arrow. Tubes, EHT transformers and other components that might cause a problem like this are very expensive, and they require proper resetting of all voltages and frequencies on replacement or they can burn out again very quickly. It is generally cheaper to buy a new TV. And be VERY aware that you can get a lethal shock from a tube that has been stored for months.

Sure there is. Take it to a TV repair shop but be forewarned, it ain't worth investing the money considering the prices of new flat panels. I used to repair them.

It died of old age. Have a funeral and bury it in the backyard. lol

It may be expensive to repair otherwise your old friend is dead.
