I have replaced my Logic Board, but now my display won't work
So I picked up a faulty Macbook Pro. Initially it would not power on at all. Previous owner attempted a battery change and a hard drive change, but I am unsure of the history of the machine. I do believe that liquid damage is a serious possibility though.
Anyway, I replaced the old logic board with a new one, and after some work fiddling with batteries and keyboard ribbons, I powered on!
The machine gets to the startup chime, the screen flashes bright white for a second, and I can see some vertical lines, before it goes black.
I figured this might be due to the previous hard drives not being formatted correctly and such, so I removed them and attempted to boot from a USB drive with a Mavericks install on it. The same flash of white and then nothing. However, I can hear the voice from the install asking me what language I want to install in, which means that's loading up.
So, now what? Is it possible that whatever damaged the old logic board damaged the display? I've tried to get it going on my PC monitor with the adapter but I can't seem to get a signal. I'm not sure if that is because it doesn't work, or because I'm doing it wrong, so directions on how to load onto an external monitor when you cannot access OSX would be great too.

Is the new Logic board a "new" logic board?

No, it a used one from a reputable dealer. I cleaned it and applied the thermal paste.

Do you have an external display to plug-in to see what it can tell us?
Or do you have a second mac which you can interconnect in Target mode? How to use and troubleshoot FireWire target disk mode

I have an external display, and the adapter. I'm kind of new to macs though, so how do I hook up to an external display without access to OS X? Just plugging it in doesn't seem to work. I do have a second Late 2009 Macbook (not pro) though, would that work for firewire?
