Does anyone know what the vacuum level of a CRT television is?
Thanks
Thanks
In summary, the vacuum level in a CRT TV is important for its proper functioning by creating an environment free of air molecules. It is maintained during manufacturing using a vacuum pump and sealed to prevent air from entering. The ideal vacuum level is around 0.01 Torr to allow electrons to flow freely without causing damage. However, the vacuum level can change over time due to various factors, resulting in a decrease in image quality or even complete failure. Signs of a low vacuum level may include decreased image brightness, clarity, and color accuracy, as well as strange noises coming from the TV. If suspected, it is best to have a professional check and repair the TV.

In the 10-6 Torr range.
Incidentally, this is an extremely easy fact to find using any major search engine.

But you did already. Says right there, "PF Contributor".
Related to What Is the Vacuum Level of a CRT TV?
1. What is the purpose of the vacuum level in a CRT TV?
The vacuum level in a CRT (cathode ray tube) TV is crucial for its proper functioning. It creates an environment free of air molecules, allowing electrons to flow freely from the cathode to the anode, creating the image on the screen.
2. How is the vacuum level maintained in a CRT TV?
The vacuum level in a CRT TV is maintained by using a vacuum pump to remove air from the tube during manufacturing. The tube is then sealed to prevent air from entering and disrupting the vacuum.
3. What is the ideal vacuum level for a CRT TV?
The ideal vacuum level for a CRT TV is around 0.01 Torr. This is low enough to allow electrons to travel freely, but high enough to prevent damage to the cathode and anode due to high voltage.
4. Can the vacuum level in a CRT TV change over time?
Yes, the vacuum level in a CRT TV can change over time due to factors such as temperature changes, manufacturing defects, or damage to the tube. This can result in a decrease in image quality or even complete failure of the TV.
5. How can I tell if the vacuum level in my CRT TV is low?
If the vacuum level in your CRT TV is low, it may cause a decrease in image brightness, clarity, and color accuracy. You may also notice a buzzing or humming sound coming from the TV. If you suspect that your TV has a low vacuum level, it is best to have it checked and repaired by a professional.
