[QUOTE="pigoo3, post: 1581647, member: 56379"] I think that if this detail was mentioned before…it must have gotten lost with all of the other details (sorry). I did a quick look on a couple sites…and a display inverter isn't listed either. I believe that the inverter part is a part that is required with LCD displays. Your MacBook Pro has an LED display (if you identified it correctly)…which I don't think has or needs an inverter. So your MacBook Pro doesn't have an inverter. On the part sites…only a display panel and video cable are listed for your computer (parts related to the display). I don't really think that the display panel or the video cable itself would have gotten damaged in a liquid spill…which again…leaves the logic board as the problem area. Maybe there's a signal that comes from the logic board…to/thru the video cable…then to the display...that triggers the change in brightness of the display. Just like what would happen when the display brightness is adjusted on a working computer. That signal comes from the logic board. So it's possible that the circuitry that is responsible for display brightness got damaged in the liquid spill. - Nick [/QUOTE]
