All 3 HDMI ports are failing to recognize any inputs from my cable box or Apple TV.  I've replaced both the cable box and cables  - still not signal.

 

Model # UN43MU630DFXZA

 

Please help!

Mine was 14 months old and the HDMI ports failed one at a time.  Then the sound started acting up.  The guy that replaced the board said that Samsung uses proprietary HDMI chips.  No doubt poorly designed. 

I'm still having some issues.  Apparently, the Samsung TV wants to see strong HDMI signals and some devices (my TIVO Bolt) are lower than it likes. Even though the TIVO works on virtually every other TV.
