Well, I didn't know where to post this...but it's here now:)

I removed a flyback from my colour monitor and after removing it I succeeded in breaking what seems to be (or closely connected to) the ferrite core. It is a metallic (I think, it is cold to the touch) piece, black on mine, in the shape of a U with a metal clamp holding it tight, it is on the outside of the flyback, my question is, did I break the flyback? or just a piece that wasn't necessary.

I put the CRT HV connector in one hole on the monitor plug in and one end of a neon-light tester in the other hole, and then put the other end of the tester on the one lead of the flyback, now I got a light to light up, as if it was good. The tester has 3 lights and one top "thing" (I say thing because I'm not exactly sure what it is) and only the bottom light comes on, the same as if I plugged it into a wall plug.

kyle_soule,
Sounds like a screw up to me
you can check this link for information;

I will tell you what might work; Don't put glue on the broken areas, but press them together tightly and find a clever way to glue it on the sides.
PS I'm a real whiz with adhesive repairs and you can PM me if you need more detail.
Best of luck to you.
 


First of all, I want to commend you for seeking help and trying to fix the issue yourself. It takes a lot of courage and determination to do so, especially when it comes to electronic components like a flyback transformer.

Based on your description, it is possible that you may have damaged the ferrite core or a closely connected piece while removing the flyback transformer. However, it is difficult to say for sure without seeing the actual damage.

As for the test you conducted with the neon-light tester, it is not a foolproof way to determine if the flyback is still functional. It is always best to use a multimeter to test the resistance and continuity of the transformer. If the readings are within the expected range, then the flyback is most likely still functional.

If you are not experienced with repairing electronics, it is best to seek professional help or replace the flyback transformer entirely. Attempting to fix it without proper knowledge and tools can be dangerous and may cause further damage.

In the future, it is important to handle electronic components with care and follow proper procedures when removing them. This can help prevent accidents and damage to the components.

I hope this helps and good luck with fixing your flyback transformer.
