Answer to "What components need replacing on the Logic board?"After reading posts from Willi and others on how to repair the 24" LED Cinema Display, I am happy to report that my monitor is working again. I found someone on Kijiji to perform the soldering for a reasonable price. As noted by others, you cannot change the brightness level and in my case it was too bright for my eyes after more than 15 minutes of looking at the screen. I'm using a Neutral Density Gel Filter sheet (made by Lee Filters for $10) over the screen to reduce the brightness. Hope this may help others that experienced the same problem with brightness.
