Why does the TV not see HDMI?

Question

Iron

Good evening. The essence of the problem: earlier, when connecting a laptop to a Samsung TV via HDMI, everything worked. Then after a time. Now it doesn't work at all. The cable is in order, the prefix sees. The laptop also has nothing to do with it, it connects to the display from the computer. How to solve this problem?

Answer 1

The completeness of the input data is missing:

• MB updated the firmware on the TV? If the cable / laptop / Windows on the laptop are the same, then you yourself understand where to dig ...
  
• mb updated / changed Windu / firewood / BIOS on the laptop?
  
• Are you already using another mb cable? although they are the same, they are still different (I don’t know the nuances of all, but this is a fact)
  

The laptop also has nothing to do with it, it connects to the display from the computer

well, that's not a fact: a monitor from a PC is just an image output according to the parameters of the laptop, and the TV processes / encodes or something like that (I don’t know how to call it exactly) the signal from your laptop before displaying it on the screen.
The fastest option that came to mind: try to take and throw another laptop and display the image on TV from it - you yourself will understand further where you will need to dig.
ps I have + - something similar once happened, but it was the BIOS update on the laptop that was to blame.

Answer 2

Beech while charging is worth it? And then I had such a jamb, so it was just that the power fell out of the beech and it went into economy mode, switching to another vidyuhu.
