Ersterhernds iMac G5 20 Inch A1076 Project

Thx for your reply! The inverter is working properly as far as I can see, the lights do go on when I plug the power cord in, the brightness control pin is disconnected, that means full backlight right?

 

Something has run amok with your soldering likely. Heres a link to some photos of how I achieved a solid connection, using the wire leads clipped off some resistors, then sealed firmly with JB Kwik Weld which is 100% non-conductive.

I used this method on my last two A1076 builds that I completed for other family members. It was easier and much more secure (less fragile) than the first build I did. Wish I'd known sooner.
