No Video on MacBook Pro Display
I recently bought a MacBook Pro off of eBay that had a liquid spill. I figured this fried the system board (which is fine, i just wanted it for the case anyway). Well, I took out the logic board and followed the steps for reflowing (a.k.a. baking the logic board since i had nothing to lose.) I put the logic board back in and lo, and behold, I got the boot-up chime, but no video. So I plugged it in to an external monitor and it worked great. Well, I obviously wanted to use the laptop without an external monitor, so I took the logic board out of a known good computer (with a beat-up aluminum casing... the reason i wanted to get the MacBook with the fried logic board) and placed it in the new case. Same thing, boot up chime, no video.
Soooo, I figured it was a bad LCD, so I pulled the entire display off of the old MBP (known to be good and working) and put it on the new case. Same thing, boot up chime, no video.
I do know that both laptops are the Mid-2009 MacBook Pro. I know that the old system board was working fine and, as I mentioned previously, the display assembly off of the old unit worked fine.
Would there be ANYTHING that I'm missing here? Can anyone think of why this could be happening? Thanks so much in advance.
