System doesn't boot (black screen) after HAT1127H, onewire chip fix.

After water damage I replaced HAT1127H and onewire chip.

I know the parts replaced were successful as the charger indicator on the charger now turns green and orange and the battery charges. Furthermore, when the power button is now pressed the fan and hard drive spin-up.

I have also tried SMC and PRAM reset as well as hooking the device up to an external monitor, all to no avail. Any ideas?

Here is an image before the fix:

Any other components that could be keeping the device from going into a normal boot?

Looking at your image I do some more corrosion damage around the display connector. How about posting a fresh set on images covering both sides of the logic board as sharp as you can get so we can see what else needs cleaning or if something else needs replacing.
