A cathode ray tube (CRT) emits light when electrons strike the front of the glass tube that is covered in a phosphor coating. The front of the tube is the anode of the tube. The electrons are fired from the rear of the tube by an electrode called the cathode.
The electrons are formed into a beam or ray, hence the name of cathode ray tube.
Although the electrons travel from the rear of the tube to the front, or from the cathode to the anode, conventional current actually flows the opposite direction. So, the current, as measured in amps will flow from the anode to the cathode.
Those were picture-tube TVs. The picture tube was almost as long as the TV screen was wide.
The picture tube is the main component of a television set.The picture tube is the main component of a television set.
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.
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.
Monochrome generally indicates a black and white picture.
Why not!Smashing the face of the picture tube will cause an implosion.
If the deflection yoke is rotated it can cause a slanted TV picture. The deflection yoke is located on the tube neck inside the TV.
Dim picture, slow to get bright and the white part of the picture turns kind of negative looking.

panasonic? 15 years?,,,,,,,,,,,,, I am sure the tube is going out.
The CRT refers to cathode ray tube. This is the oldest of the varous TV types. More recent developments have been projection, plasma, etc.
If you mean display type, then there are rasterized picture tube televisions, LCD televisions, and plasma televisions.
