HDMI no signal

[sn23]

I used to connect my NintendoSwitch to my QLED but moved it to another TV. Now I am back to the same TV but it's showing no signal. 

it seems like it recognises my Switch but there is no signal. Tried it on my other Samsung TV and it works fine.

Have you tried using a different HDMI cable or plugging it in a different slot? I see it's in HDMI 2. What happens when you plug it in HDMI 1 or what is using the HDMI 1 slot.

Yes tried with different HDMI. And same thing happened when I moved to HDMI1
