Apple TV keeps restarting on LG 4K TV

I thought its it’s HDMI cable fault but after I changing the cable, I have the same problem of restarting so I changed the TV. By the way I have a LG 4K . on other TV My Apple TV start working well without any restarting. so I think it’s the new update fault because some TV is not working well with Apple TV.
