iMac has a black screen, could it be the Inverter?

Been looking through similar posts but my problem appears to be different to those i have read.

I have no way of connecting the imac to another display at the moment, but everything appears to be functioning correctly except the dead lcd. I managed to get a cd to play in itunes by putting in a cd so im guessing its not a problem with the logic board?

First time this happened was about three days ago, the screen went to black but with a hint of brightness.So after shutdown and leaving for a few minutes the screen is back to normal.

Yesterday the same thing happened, and after rebooting i would get the usual grey apple start up screen and now to a completely black screen at the point you would login. After many attempts, i now have just a black screen at start up with no apple after the chime. I can still play a CD.

Ive managed to find the same inverter i need online, but would like some opinions on this before i go ahead and buy. Hopefully there is not a problem with the LCD. Thanks for any advice! Great site BTW!

Answer this question I have this problem too

Is this a good question?

Hold a flashlight to the screen at an angle and see if you can discern the desktop.


No nothing, by the way i should have said. Only L.E.D's 1 & 2 are on.


Also what cable would i need to plug into another imac, or hd tv?


In a repair center we've seen a greater number of 0KM iMac having video problems...


Pretty sure its the graphics card now as im not getting any output on an external display. Is there a guide on here for removing the gfx card? I could only find it for the 2009 20" EMC 2133 model.
