My intentions are to mess as little as possible with the actual circuit and components, so I'll just build a new frame around it. I know that one should approach a CRT . What I would strongly recommend is that the TV sit for as many hours as you can get away with before even plugging it in. 12-24 hours at least would be my guess. That way .

If any electrical hardware is damaged by any voltage down to zero, then it was defective before it was purchased. If a blackout does damage, then any other power off does .They run high enough voltage to kill you if you open them up and touch components without knowing what you're doing. Otherwise, they are fairly innocuous pieces of equipment and only . CRT TVs use the flyback transformer to generate voltage levels of about 20 to 30 kilovolts to accelerate electrons inside the tube. That is much more than the about 2 to 10 . Keep your nose alert! Lightning can create a unique smell of burnt electronics. So, if you catch a whiff of any unusual or strong odors coming from your TV, it’s a sign that a .

"Surely electricity cannot zap me through the air?" It can if it's sufficiently high voltage. That's what arcing is, like tiny lightning. Does this answer your question? How .WARNING: that doesn’t meant you’re safe. The tube can hold a charge of over 30KV for years and it will rock your world. So you’ve got a power supply problem or a failed flyback . Some CRT/yoke combinations just end up working out better than others due to tolerances. The service manual might even have specs on how far out the convergence can .

CRT TV crackles when powered up or emits a strong electrical odor. This is not a very common problem. The most prominent reason is cathode ray tube failure. The minor crackling noise is due to high voltage arcing. The possible reason behind the burning smell is caused by insulation burn. My intentions are to mess as little as possible with the actual circuit and components, so I'll just build a new frame around it. I know that one should approach a CRT circuit with caution. Capacitors inside can hold some serious charge (thousands of volts). What I would strongly recommend is that the TV sit for as many hours as you can get away with before even plugging it in. 12-24 hours at least would be my guess. That way you reduce as much as possible any risk of electrical excitement. If any electrical hardware is damaged by any voltage down to zero, then it was defective before it was purchased. If a blackout does damage, then any other power off does same hardware damage. Power cycling is destructive to switches.

"Surely electricity cannot zap me through the air?" It can if it's sufficiently high voltage. That's what arcing is, like tiny lightning. Does this answer your question? How dangerous is it for me and the TV to open up my CRT TV to dedust it with compressed air? I have worked on about 25 with no shocks , never waited as long as an hour. I would greatly appreciate any opinions on my design, particularly in regards to electrical safety with CRT tubes. The TV is too wide to fit inside my custom arcade cabinet due to the built in speakers on the side.

WARNING: that doesn’t meant you’re safe. The tube can hold a charge of over 30KV for years and it will rock your world. So you’ve got a power supply problem or a failed flyback transformer. To be honest, you’re probably dealing with a piece of e-waste. That era of CRT set really wasn’t meant to be repaired.CRT TV crackles when powered up or emits a strong electrical odor.

They run high enough voltage to kill you if you open them up and touch components without knowing what you're doing. Otherwise, they are fairly innocuous pieces of equipment and only risk falling from poor tv stand or earthquake. CRT TVs use the flyback transformer to generate voltage levels of about 20 to 30 kilovolts to accelerate electrons inside the tube. That is much more than the about 2 to 10 kilovolts required to produce ozone. Any exposed high voltage can create a corona discharge that produces ozone. Keep your nose alert! Lightning can create a unique smell of burnt electronics. So, if you catch a whiff of any unusual or strong odors coming from your TV, it’s a sign that a lightning strike might have caused some damage. When lightning strikes, it .
