The TV flyback transformer is obsolete in modern television sets and is not used.
In the old cathode ray tube (CRT) television sets the flyback transformer had two functions:
- generate a large and powerful current pulse to drive the horizontal deflection coil in the yoke around the neck of the tube to create a quick horizontal retrace between sweep lines
- using a large secondary autotransformer winding produce a very high voltage (i.e. 15KV to 100KV) rectified by a high voltage diode needed by the anode of the CRT to accelerate the electron beam

What is the name of the circuit connecting to a CRT tube in a TV?
The flyback. (99% sure - its been a while)
What is application area of autotransformers?
teslacoilcar ignition coilCRT television set flyback coilother transformers intended to produce extremely high voltages at low costvariacetc.
What is a flyback?
A type of high voltage transformer. Their most common use was in CRT based TVs & computer monitors to generate the anode high voltage and horizontal sweeps.
If a television high voltage regulator opens what is the likely to be the symptom?
In most sets, the HV regulator actually regulates the B+ voltage to the horizontal output transistor and the flyback transformer. A bad regulator indicates high current or loss of horizontal drive. Check the flyback transformer, the HO transistor and also look for proper waveform and voltage from the horizontal driver transistor/chip.
What is a flyback inverter?
fly back inverter is such kind of DC-AC inverters which use the flyback transformer for the low dc-high dc stage of the inveter shortly it's DC to AC inverter with flyback transformer inside .

Is a tv main and power and the flyback transformer the same thing?
the main or power transformer is your iron and copper variety to get all the voltages to supply various circuitry fly back is ferrite in a resonant tank on the 15Khz to get the 10Kv for the second anode of the crt
What is the historical function of the television?
The historical function of the television is an entertainment and marketing device. Originally the entertainment function was primary, but advertising and revenue it generates has become the primary function.
What causes sparking?
It depends on the type of sparking/arcing. If you mean in a DC or series-wound motor, it is caused by the making and breaking of the commutator segments against the motor brushes.If you mean under a car, then it could mean that the muffler is dragging the ground.If you mean in a CRT television, then it is likely problems with the flyback transformer.
How do you know when picture tubes go in a tv?
The most common failure mode of the CRT in a TV is the picture going progressively darker and darker. In general, if the TV wouldn't display anything at all suddenly, there can be more at work than just the tube suddenly going bad - I'd even go as far as to say that in most cases of unexpected, abrupt failures, the tube isn't to blame (the flyback transformer is a much more likely suspect).
Energy forms televisions?
Televisions in general make use of light energy to function
How types are SMPS?
