Hi, I have found you a service and repair manual at the below website, inside this manual, is ALL the necessary facts to enable you to troubleshoot and repair.
Above is a picture of a bad xformer...as you see they are NOT much different that a normal good one. You need to test these units with a meter or a FB tester.
Usually the "Chopper" transistor, The power transistor that"Drives" the FBT, is what fails in the Flyback circuit, and that's what we suspect most when there is NO output from the FBT.
The FBT's don't really fail that often, but they do indeed fail, one must check as said with a meter, on OHMS,and we look for shorts or usually Open circuits, The FBT is wound like an autotransformer and has a common winding, & various outputs.
In any ebvent please download your service manual and perform the troubleshooting steps in there you should be able to sort iot no problem.
Another thing to look for is shorted ceramic caps in the various outputs from thre FBT.
