What is cost of flyback T404 in India

I have the same problem with a samsung 750s, the original flyback borke, and i replace it with a new one, (not the original) and in a couple of month it started to do get fussy with temperature. I will replace the flyback with other brand fly back

its so easy my friend, just throw them to the river.
