The Computer Keep track of flyback transformer will come with quite a few varieties of pieces number, developed and inductance winding values. Although some might have distinct element quantities, they can be use d to substitue on a further model of monitor! The Check flyback transformer is manufactures by numerous unique companies thus lots of various forms of section numbers are manufactured. If you know particularly the winding price of each and every flyback transformer then it is simple for you discover a replacement.
One particular very good illustration is the Samsung Samtron flyback transformer with a element selection of FKD15A001 and it is the very same as FKG15A001. Another very good element selection is the Acer observe-19.00026 which is exact as 19.00038. In buy to uncover out whether or not a particular flyback transformer can be switch with yet another aspect variety or even with a different model of flyback transformer is to use an inductance meter. It is compulsory to have just one.
Usually a watch flyback transformer have couple of pins which are essential these kinds of as the B plus (+) pin, horizontal collector pulse pin, G1, AFC (computerized frequency control), X-RAY Defense pin, ABL (computerized blanking limiter), floor, and horizontal centering pin. If you want 100% guaranteed that the substitute flyback transformer can do the job for your personal computer watch, you have to initial estimate the inductance values for each and every winding this sort of as what is the key winding inductance worth, between ground to AFC and ground to G1.
The winding tolerances should be all over 5-10 p.c and please make confident you know which pin you are measuring. Let’s say the first flyback key winding (B+ pin and collector pulse pin) have a inductance benefit of 1.5 milihenry then the substitution flyback really should have a benefit between 1.45 to 1.65 milihenry. If the winding inductance price is far too substantial or also lower, it will prompted the check horizontal dimensions display to gets also significant or much too little horizontally and even can burn off the Horizontal output transistor (Incredibly hot) in a really shorter time.
Your following try out is to uncover out the value of Floor to G1, Floor to AFC and so on. If you want to find out the ABL pin you can generally refer to my electronic maintenance internet site which is at the bottom of this posting. Proudly owning a flyback transformer schematic or circuit diagram is the finest way to uncover the accurate pins. If you will not have the info then you have to obtain the pin with the enable of inductance meter. From time to time, looking the Web will support you get the flyback schematic.
It may possibly get you a lot of time to recognize the artwork of tests the inductance price of flyback but the time you have shell out is very well worth and who understands one working day you can find the proper substitution of monitor flyback transformer even with no the assist of a flyback transformer cross reference schematic. One final term, irrespective of whether it is a Imac, Hitachi, Sony, Rca Tv, or any form of flyback transformer, the methods of locating the alternative is the exact same. It just desires tricky function these as examine the some flyback schematic diagram and get started to exercise with the help of your inductance meter.
