Why are the return, home, and search buttons on my Galaxy Tab 3 not working/ lightening up?

[AC Question]

Why are the return, home, and search buttons on my galaxy tab 3 not working/ lightening up?

I replaced the charging flex cable and instantly noticed that the home button was completely useless while the return and search button were working but not lightening up. I'm looking at having possibly disconnecting the digitizer flex cable which is next to the charging flex cable (I may have disconnected it).

Have you checked to see if you disconnected it?

I had this problem and a RESTART fixed it for me!
