Personal computer Watch Flyback Transformer – Replacement and Substitution
The Laptop or computer Watch flyback transformer will come with a lot of varieties of areas number, designed and inductance winding values. While some may well have diverse section numbers, they can be use d to substitue on one more model of keep track of! The Keep an eye on flyback transformer is manufactures by lots of distinct suppliers thus numerous various forms of part quantities are manufactured. If you know just the winding value of each flyback transformer then it is effortless for you find a substitution.
Just one very good case in point is the Samsung Samtron flyback transformer with a aspect number of FKD15A001 and it is the same as FKG15A001. A different very good element variety is the Acer observe-19.00026 which is exact as 19.00038. In purchase to obtain out irrespective of whether a specific flyback transformer can be substitute with an additional aspect range or even with a different manufacturer of flyback transformer is to use an inductance meter. It is compulsory to have a single.
Typically a watch flyback transformer have number of pins which are vital these as the B moreover (+) pin, horizontal collector pulse pin, G1, AFC (automatic frequency command), X-RAY Security pin, ABL (computerized blanking limiter), floor, and horizontal centering pin. If you want 100% positive that the substitute flyback transformer can get the job done for your computer system monitor, you should initially work out the inductance values for just about every winding these types of as what is the most important winding inductance worth, among ground to AFC and ground to G1.
The winding tolerances really should be all around 5-10 % and remember to make sure you know which pin you are measuring. Let us say the first flyback main winding (B+ pin and collector pulse pin) have a inductance benefit of 1.5 milihenry then the substitution flyback ought to have a value between 1.45 to 1.65 milihenry. If the winding inductance benefit is as well substantial or much too reduced, it will triggered the watch horizontal size display to gets too massive or also compact horizontally and even can burn off the Horizontal output transistor (Warm) in a pretty limited time.
Your up coming test is to come across out the worth of Ground to G1, Floor to AFC and so on. If you want to locate out the ABL pin you can generally refer to my digital restore web site which is at the base of this short article. Possessing a flyback transformer schematic or circuit diagram is the best way to uncover the right pins. If you will not have the information and facts then you have to come across the pin with the aid of inductance meter. Sometimes, looking the Online will enable you get the flyback schematic.
It may get you a whole lot of time to understand the artwork of tests the inductance price of flyback but the time you have commit is well worth and who is aware just one day you can locate the right substitution of observe flyback transformer even devoid of the assistance of a flyback transformer cross reference schematic. One particular very last word, whether it is a Imac, Hitachi, Sony, Rca Tv, or any style of flyback transformer, the ways of getting the substitute is the identical. It just desires tough get the job done such as review the some flyback schematic diagram and commence to practice with the aid of your inductance meter.
