Great restoration work! Do you have any photos of the final result?
Also, I would be very interested the "stickers" (you called them) for all the front panel graphics restoration. How did you create these? What was the application process?
Any reason you didn't go for a completely new, modern back-lit display? (Instead of just retrofitted a light to the original one.) Today's LCD displays have higher contrast and much faster response time.
Or, better yet, use an OLED display, which have a 180 degree field of view. I replaced with the display in my Alesis MMT-8 with an OLED and it looks sharp! I plan to do my CZ-101 someday. Speaking of Casios, I'm also in the process of replacing the backlight on my VZ-10M (not the LCD display itself, just the backlight) with a backlight from an iPhone.
Thanks,
