Cathode ray tube (CRT) TVs can pop even when turned off due to the release of built-up energy or the discharge of high-voltage components, particularly in the flyback transformer or the capacitors. These components can retain electrical energy, which might suddenly discharge, creating a popping sound. Additionally, thermal expansion or contraction of materials inside the TV can lead to mechanical stress, resulting in popping noises. Dust or debris inside the CRT can also cause arcing, contributing to these sounds.

Do LCD TVs use cathode ray tubes?
Some early flat screen TVs used cathode ray tubes, but the flat faced tubes were harder to make and heaver than the older curved faced tubes. When newer designs (e.g. plasma, LCD, LED) came out that naturally produced flat screens and were lighter weight than cathode ray tubes, they rapidly made flat screen cathode ray tube TVs obsolete.
Why it is possible to have a wider screen in televisions than in cathode ray oscilloscopes?
Hell no pee head
Can you used cathode ray oscilloscope as television?
Yes, some could be used for analog monochrome TV but lots of extra circuits would be needed. Picture would be green. Cost of oscilloscope would likely be several times a portable analog TV of similar size, even before adding extra circuits.
How rays can be produce by cathode ray oscilloscope?
A: xray emits from TV, OSCILLOSCOPE and some more instruments due to requirement of hi voltage to see the display
What type of particle are cathode rays made of?
electrons A: It is basically a glass vacuum enclosure whereby electrons are emitted from a cathode by a heating element. A grid control the flow of these electrons and finally hit the face of the tube where is rare earth materials emit photons
Why television are also known as cathode ray tube?
because cathode ray tube is the heart of the television.
What is on the cover of Calculating Infinity album by The Dillinger Escape Plan?
It's a cathode from a very old cathode ray tube. It is the far end part of an old television cathode ray tube (used in other machines than television too).
What is the full meaning of CRT in computer?
A "CRT" is a cathode ray tube. An old style computer monitor (not computer).
Where the cathode ray oscilloscopes are used?
Television, Computer Moniters
What is an example of a cathode ray tube found in most American homes?
Cathode ray tubes are the screens of old fashioned televisions and computer monitors.
What is the full form of You tube?
Your Television. You - Your Tube -Television (From Cathode Ray Tube)
Is a cathode-ray tube and an iconoscope the same thing?
No. A cathode ray tube uses cathode rays to (among other things) scan a phospher and generate an image. An iconoscope is similar, in that its uses cathode rays to scan, but it scans a light sensitive area so, instead of generating an image, the iconoscope scans an image. It is a television camera, instead of a television set, so to speak.
Can a television shock you?
Yes, is the short answer. Old TVs with a cathode ray tube, can build up a static charge on the front of the screen. You can sometimes get a harmless shock if you touch it when working. These old TVs also generate a very high voltage inside, to accelerate the cathode rays. The tube can act like a giant capacitor and store this charge even when switched off and unplugged. Keep your fingers out of the back, unless you take professional precautions. All other TVs, including LCDs and Plasma, have power supplies which store high voltage in their capacitors. This voltage is also maintained even when the TV is switched off and unplugged. Again, you are safe as long as you keep your fingers out of the workings. Qualified personnel are knowledgeable of the stored voltages and know how to deal with them safely.
