Computer Monitor Flyback Transformer – Replacement and Substitution

The computer monitor flyback transformer comes with many kinds of part numbers, designs, and inductance winding values. Although some may have different part numbers, they can be used to replace them with another monitor model! The Monitor flyback transformer is made by many different manufacturers, which is why many different types of part numbers are produced. If you know the exact winding value of each flyback transformer, it will be easy for you to find a replacement.

A good example is the Samsung Samtron flyback transformer with part number FKD15A001 and it is the same as FKG15A001. Another good part number is Acer monitor-19.00026, which is the same as 19.00038. To find out if a particular flyback transformer can be replaced with another part number or even another brand of flyback transformer, you need to use an inductance meter. It is mandatory to have one.

Normally, a monitor flyback transformer has few pins that are important, such as pin B plus (+), horizontal collector pulse pin, G1, AFC (automatic frequency control), X-RAY PROTECTION pin, ABL (limiter blanking), ground, and horizontal centering pin. If you want to be 100% sure that the substitute flyback transformer can work for your computer monitor, you must first calculate the inductance values ​​for each winding, like what is the inductance value of the primary winding, between ground to AFC and ground to G1.

Winding tolerances should be around 5-10 percent and make sure you know which pin you are measuring. Let’s say the original flyback primary winding (pin B+ and collector pulse pin) has an inductance value of 1.5 millihenry, then the replacement flyback must have a value between 1.45 and 1.65 millihenry. If the winding inductance value is too high or too low, it will make the monitor’s horizontal size screen become too big or too small horizontally and it may even burn out the horizontal output transistor (HOT) in a very short time.

Your next attempt is to find out the value of Ground to G1, Ground to AFC, and so on. If you want to find out the ABL pin, you can always refer to my electronic repair website at the end of this article. Owning a flyback transformer schematic or circuit diagram is the best way to find the correct pins. If you don’t have the information, you need to find the pin with the help of the inductance meter. Sometimes searching the internet will help you get the return scheme.

It may take you a long time to understand the art of testing the flyback inductance value, but the time you’ve spent is well worth it, and who knows, one day you may find the right monitor flyback transformer replacement, even without the help of a flyback. transformer cross reference schematic. One last word, whether it’s an Imac, Hitachi, Sony, Rca TV, or any type of flyback transformer, the ways to find the replacement are the same. You just need hard work like studying flyback schematic diagram and start practicing with the help of your inductance meter.
