Stay with this guys, you're hlepnig a lot of people.
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.
A vacuum is needed in the deflection tube to prevent the interference of air molecules with the movement of electrons. Air molecules can scatter and absorb electrons, affecting the accuracy of the electron beam's deflection. By removing air and creating a vacuum, the path of the electrons remains unobstructed, allowing for precise control and movement within the tube.
A picture tube is that big glass thing you look at that the picture appears on. The back of it has a regular tube socket.
It is not necessary in a cathode ray tube, it is a side effect and is needed in the calculations to ensure that there are no errors.
They are created by the electron gun in the back, deflected by the deflection grids to move up and down and left to right, and then travel towars the front of the screen where they excite the phosphors coating the inside of the glass.

If this is an older analog (CRT tube) type television and since it `occasionally happens' it sounds like you have a bad (intermittant) solder connection somewhere in your vertical deflection circuit.
The solution to a cathode ray tube physics problem involving electron acceleration and deflection is to apply the principles of electromagnetism and the laws of motion to calculate the trajectory of the electrons as they are accelerated and deflected by electric and magnetic fields within the tube. By solving the relevant equations, one can determine the path of the electrons and predict their behavior within the cathode ray tube.

Those were picture-tube TVs. The picture tube was almost as long as the TV screen was wide.
A Coriolis transmitter is a component of the Coriolis flowmeter. It transmits the information gathered by the flow tube sensors. This type of flow meter is used to measure the mass flow rate and density of a fluid.
Answer: Generating a picture on a TV employs a different technology than that of a video card for PCs. Today's television picture tubes have shadow masks that are manufactured from a nickel-iron alloy called Invar; while lesser quality sets have masks of iron. The alloy allows the tube to operate at a higher temperature without distorting the picture, and higher temperatures allow brighter pictures. Rare-earth elements have also been added to the phosphor coating inside the tube to improve brightness. The electrons are fired by three tubular, metal electron guns that are carefully seated in the neck, or narrow end, of the tube. After the electron guns are placed inside the tube, the picture tube is evacuated to a near vacuum so air does not interfere with the movement of the electrons. The small opening at the rear of the tube is sealed with a fitted electrical plug that will be positioned near the back of the set. A deflection yoke, consisting of several electromagnetic coils, is fitted around the outside of the neck of the picture tube. The coils cause pulses of high voltage to direct the scanning electron beams in the proper direction and speed.
