I just got an older 12" Powerbook off of eBay. The seller said that the display was damaged from a spill. When I received it, it powered on fine but I noticed that I could still see everything on the screen, just had to look real close or open things up against a white background. I assumed that it needed a new inverter board. I got a working one but when I installed it, it didn't solve my problem. So I pulled a working screen (display, lcd, inverter, etc.) off of another 12" Powerbook and installed it. The screen is still dim!!! Does anyone know what else I can do to solve my problem?
