I just replaced my cd drive with a SSD and replaced my hard drive. During the process I took the keyboard backlight out to fix some of the color sheets i had added a long time ago to make the backlight rainbow colored. I tested the led's before reinstalling the backlight sheet to make sure everything was working. I also wore a grounded anti-static strap the entire time i was working on the computer.
After realizing it didn't work on the next boot, I took it apart and replaced with another sheet from the original keyboard (which I had replaced a couple years ago). booted, and found that one didn't work either. I retested the LED's from the newer sheet and 2 were dead. (which might stop the whole line from working, idk.) I haven't tested the ones that are installed because i don't want to take the computer apart again unless it's going to fix something.

Repair attempts:
- Tried replacing backlight sheet
- reset pram
- reset smc
- reinstalled OS
Extra info:
- If In the keyboard sys pref pane, there is still an option to dim backlight. enabling or disabling makes no difference.
- light levels make no difference, same problem in dark as light.
- F5/F6 keys respond and raise bars on screen, but backlight doesn't light up.
- tried plugging in sheet on outside, no help.
- cable is firmly connected and all the way in.
