Return LED not lit after LCD replacement. Button working fine.

Hi there,

I've replaced the LCD on a Galaxy S5 for a friend. After I turned it on when I was done, I noticed the return/back LED is not lid.

The menu LED is lit, and both buttons are responsive.

Does anyone have any experience in this? I can't seem to figure out how to fix this issue.

I must admit I actually don't know if it was lid before I got it.

I have been through the settings where I can turn them on / off with no luck.

Best Regards
