Keyboard Backlight only glows in center
NOTE: I am aware of this thread Keyboard backlight only glows in center but my problem is not caused by a spillage.
I've been repairing a macbook pro for the last couple months on and off.
I've learned a lot along the way and have realized some things I did wrong.
The keyboard was sticky so I replaced it, but ended up I guess damaging the kb backlight because it now does not work. It diffused evenly among the keys before.
I now bought a replacement keyboard backlight, and it diffuses brightly to the few center keys then very dimly among the others, and only shines through the letters of the few center keys and none of the others.
I've re-inserted the LEDs in the plastic film to make sure they are correct placed, and I still have the same problem.
I have a feeling that it is a problem with the backlight I purchased, which even though states is compatible with my model looks quite different than the original I have.
Should I buy another one from a different seller and retry?
Could it be a problem with the replacement keyboard?

Is this a good question?
