Few days ago in our place we had thunderstorm, and after that our satellite receiver spoiled. After that we call service and they changed the receiver, where the problem started. On TV(Samsung JU6702), all HDMI ports aren't working(TV had four). When i push SOURCE button, TV changed on HDMi port and TV is searching for update, but i had the latest update. BTW i started again update directly from TV, and also later with USB but nothing changed.
I also try with different HDMI cabel, nothing happens.
On the second TV, receiver works.
