screen goes black but I can see with a flash light.

iMac Late 2009 EMC 2374 SN W89524BB5PJ

Hey everybody.

I have this iMac late 2009 and the screen starts to go black a few days ago, I did a SMC/PVRAM Reset, but this did not solve the problem.

So i started to investigate and try to point a flash light to the screen and saw that it was working but almost without brightness, what do i need to do in order to repair it?

Note: I also read that if you lower the brightness it will stay on. it worked!

THank you
