Flyback crt monitor
The flyback transformer is used in the operation of CRT-display devices such as television sets and CRT computer monitors. The voltage and frequency can each range over a wide scale depending on the device. For example, a large color TV CRT may require 20 to 50 kV with a horizontal scan rate of 15.734 kHz … See more A flyback transformer (FBT), also called a line output transformer (LOPT), is a special type of electrical transformer. It was initially designed to generate high voltage sawtooth signals at a relatively high frequency. In … See more The primary winding of the flyback transformer is driven by a switch from a DC supply (usually a transistor). When the switch is switched on, the primary inductance causes the current to build up in a ramp. An integral diode connected in series with the … See more The primary is wound first around a ferrite rod, and then the secondary is wound around the primary. This arrangement minimizes the leakage inductance of the primary. Finally, a … See more • U.S. Patent 3,665,288 - "Television sweep transformer" - Theodore J. Godawski See more The flyback transformer circuit was invented as a means of controlling the horizontal movement of the electron beam in a cathode ray tube (CRT). Unlike conventional transformers, a flyback transformer is not fed with a signal of the same waveshape … See more In modern displays, the LOPT, voltage multiplier and rectifier are often integrated into a single package on the main circuit board. There is usually a thickly insulated wire from the LOPT … See more • Flyback converter • Flyback diode See more WebFlyback transformers are found in TVs and CRT monitors. They make the high voltage, high frequency current necessary to trace the electron beam across the screen. They are small and compact, and you can take them out from an old computer monitor or TV.

There'll be two adjustments on it--screen and focus. (Increasing the screen setting will give a little extra brightness to a fading monitor.) Depending on the age and size of the monitor there may be 2 focus adjustments.

WebIt used to be a real pain in physics experiments, the 15-20Khz flyback transformer produces lots of RF noise that is too low a frequency to easily screen and too high a frequency to easily chop. Fortunately we now have LCDs - with their own range of noise problems – Martin Beckett Mar 15, 2011 at 15:39 Show 2 more comments -2 WebThe good news is monitors were designed to have adjustments made while the set is on. You definitely need to read the service manual to determine the correct adjustments/test points and only use insulated screwdrivers …
