Okay, as a test, I swapped the display board from the 15C to my 16C, so I have a working 15C with mislabeled keys. :) The black plastic over the display/brains board is indeed held on with the glue from hell. I've slit it with an Xacto knife and gently scraped as much of it off as I could with a small ABS scraper. At least now, I can see the LCD frame tabs. I'm going to take a small flat-bladed screwdriver and bend them away to release the LCD. Stay tuned... --Chuck
