Keyboard backlight not turning on after upgrade

Just a follow up as well. They will flicker on everytime I tap the screen or push a hardware button. It so fast that it is only a fraction of a second.

I am starting to wonder if this is a phone issue or a ROM issue. This is a replacement phone when I did not have an XP machine to unbrick my phone from the dreaded 238 error when I attempted to upgrade my previous phone.
