Hey guys. New to this forum and I have come to see if anyone has any idea what the problem is here. I'll try to make it brief.
I have a 20" iMac (a1224 EMC 2266 2.66) that has a non functioning screen for that imac.
It outputs video just fine. It ONLY lights up gray for a second and then the screen shuts off. So I decided to try it (using the same internal video cable - as this one doesn't have one) with a 20" a1224 2316 that I had that has no screen and got the same result and the video output works just fine.
However I then hooked up the screen to a 2007 20" a1224 2133 imac and it WORKED fine. That time I used the video cable that was meant for that imac. However, it started to give me a burning smell as the 2007 and 2009's have different inverters.
So then I figured the inverter was bad on the two 2009 imacs because the screen worked fine on the 2007 one so I bought a new one cheap to try and that didn't help.
So...does anyone know what could be the problem? Is it possible the motherboard on both 2009 imacs lost its internal video functionality and can only do outputting? Or that the cable that powers the inverter from BOTH imacs is not functioning? Anybody had an issue where the screen lights up gray then turns off?
Thanks!!
