Screen blank, LED status lights #1 and #2 are on -New Question!
Model A1311 IMac Intel 21.5" EMC 2389
(PAST) I picked up this Imac for cheap (free) and thought I would give it a go to repair it. The first and second lights of the four status lights are lit which makes me think it is the video card or logic board itself...any suggestions on narrowing it down if this is the case and where/how much replacing them would be?
Is this a good question?

Ok...so here is an update of where I am at. I replaced the CPU with a I3-550 and got the third LED Diagnostic Light to come on but the screen still isn't coming on. I connected an external display via a mini displayport to hdmi adapter (which by the way there seems to be a lot of trouble with these, so I tried the vga adapter and the external now works. It looks like now I need to replace either the internal displayport cable or the LCD itself.

I have ordered a new display port cable as per the troubleshooting I have seen done on the internet and still I have no display. I am not getting the back lights to turn on or anything image on the screen as far as I can tell. There still seems to be something wrong with the logic board in my opinion. Any one else have any insight...I have seen things about the vertical sync cable, the display cable, the temperature sensor...not sure where else to go.

Ok...I am back...I had a friend loan me his imac and I tested his display on my computer...it didn't work...I tested my display on his computer and it worked. I am narrowing it down to the logic board but not sure I can even repair the board without just doing a complete replacement. Anyone come across this?
