HDMI Ports Not working

[userlXAFRx4F7b]

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!

I have a S24D300HL 24" monitor.  Suddenly, the HDMI input port will not work, and causes both displays to go black (I have extended display usinsg 2 monitors on video card).  However, if I connect with the VGA port, everything seems to work.   So the monitor is not completely broken, but the HDMI input seems to have become broken.  Please help!

I'm definitely running into the same issue, and this just started over the past week. Was there a software update released that's causing all of this?

I'm 100% sure it was caused by an update in my case. I had to wait for an update which was 4-5 months apart but that didn't fix it.

I actually sold that TV last weekend and ordered a new one different brand.

Maybe a future update could fix it but I bought it mostly to use with a Xbox and PC and it wasn't working.

 Q80 TV doesn't recognize the HDMI connecting to a Q80 soundbar.  It worked fine until two days ago. I've tried a few different hdmi cables.

I have the same problem. 75" Q7FNA TV doesn't recognize the HDMI connecting to a N850 soundbar、PC and android TV box. It worked fine until 14 days ago. I've tried a few different hdmi cables. Samsung have changed new HDMI circuit board of smart hub for me, but can't sloverd this issue. Maybe it was caused by an update of firmware of 1294.1.

 FYI Samsung Service had to come out, replace the One Connect box, it still wasnt working, come to find out the clear cable was faulty, and everything is working fine.
