Samsung Smart Tv UN50KU6300FXZA HDMI Ports no signal

Hi,

There was a power outage today and after that my smart tv's hdmi ports stop working.

It does not see cable box, apple tv or laptop connected through any of 3 hdmi ports.

I have tried factory reset, unplug wait 5 min replug still nothing.

Weird thing is when I connect my laptop to tv still there is no signal but my computer thinks its connected to it, i can see on computer menu Samsung Smart Tv.

Also when I connect APPLE tv it can control the volume of Samsung Smart Tv with Apple TV remote.

I purchased this in 2016 so I assume it is out of warranty. 

Is it an hardware issue or I can try any other firmware update, hard reset etc.

Thanks.

Disconnect the power cord from the outlet, then press and hold the power button on the TV (not the remote), for at least 10 seconds. Then wait a few minutes and plug the TV back in and press power once.

2 blinks on Samsung TV's usually indicates a bad power supply.

tv's power supply is good. I can even watch youtube on it. Only problem is the hdmi ports.

I will try hard reset.

Same with my 65" 4K. First, one HDMI port went out. Now another HDMI port has gone dead. It's a problem with Samsung TVs.
