Hi everyone, I just took out the logic board in my 2008 iMac 20" EMC 2210. I thought i had a problem with the GPU so I removed it and cleaned and put thermal paste back on. Everything went well putting back together. Start it up and hear the chime... then black screen with 2 LED's showing on the front panel. Any thoughts or could I have forgotten a cable? Please see picture as I think it may be a corroded / faulty logic board... or it could be just the GPU.
What I had before this was Pink lines on screen and could only get into Safe Boot. I was running el capitan.
