No Signal Message from the TV

I recently disconnected my Apple TV when my room was repainted. When I tried to set it up afterwards it no longer works. The front light on the Apple TV illuminates and the TV shows that there is a device connected to the HDMI 2 port. However, I get a “No Signal” message from the the TV. Any idea why this is happening? Is it a wireless network issue? Is it the Apple TV hardware?

I do get SSH access successfully and I did apt-get update and apt-get upgrade successfully.

Also reboot from SSH (Putty)

I will appreciate if any one can help me.

Thank you and I really appreciate.

I check with 3 tvs and using four different HDMI cable, still no picture or any Apple TV menu display.

Anyone has any advice or suggestion?

Thanks,

JR
