Quoted from DwightEisenhower:I ran into this issue and thought that the only viable solution was buying the lighting upgrade kit and spending a lot of hours on the project. However, I was able to isolate the GI board that was causing the malfunction by going through the LED test menu. When you select the culprit board, it will cause the lighting abnormality you describe in your post.

Make sure you have the right voltage though.
Takes about 5-10 minutes to install. It's not a permanent fix as has been mentioned multiple times on this thread but I have found that it is far easier and cheaper.
Quoted from adol75:I kept replacing the GIs board which was quick and cheap, but then one of my big boards died and replacing it was 300$, so I went with the 2.0 light kit and have lived happily ever after
So you guys are both saying that I could replace the bad board, but the root problem still exists and the only long-term fix is the $800 kit? If so, that makes sense. If you don't mind me asking, what is the root cause that causes the issue with the boards? I appreciate the responses, thank you!
I'm a little frustrated my initial inquiry to JJP years ago was brushed off when there was a known issue. But, considering this is Pinside, I'll skip the rant as I'm sure it's been expressed many times over.
