Replace or repair a dead imac screen

Hello everybody

My name is Ray.

Can you tell me if it is posible to replace the screen on a tray loading IMac.
I just but this old blue iMac at the recycle center and the screen is dead.
They have a PowerPc 5200 on stuck will this screen fit the iMac.

I check the internet for this problem, and I see the flyback transformer problem repeted often, is this part on the CRT or elsewhere, because if not it won't help to change the screen.

Can someone show me a picture of that part and explain whereit go and what it do?

Thanks!
