Thanks Leo. I'll see if I can figure out which caps connect to those pins on the DAC chip. I know I did make a slight mistake with the 100uF cap and had to re-solder it. So there is a chance it got over heated. I'll see how things go and if the brightness doesn't tone down I'll swap out that cap for a new one.
For anyone else doing the Elna cap mod, pay particular attention to the 100uF cap when mounting. As it's wider than the cap it replaces you have to bend the legs to get them closer together. When I first mounted this cap I noticed one of the legs was touching a little surface mount cap underneath it and potentially shorting. So I had to raise the Elna cap up a bit to add some clearance. None of the other caps have this problem as they're further away from other components.
