MERGED QUESTION
Question from zenabodina.2016 : "Sieki HD TV access codes"

I have no signal for channel searching on my SIEKI HD TV (3 yrs old)
I tried to "cut the cable" from Xfinity/comcast. At first, I had some channels, then mother tried to make "fit it" forgetting that we don't have cable anymore!
Now, after trying multiple times to do a reset, hard reset, 'restore default settings"
I still have nothing...
Please HELP ME!
Thanks,
Dennie, Oregon

Is your antenna attached (and powered, if applicable)? Did you scan for channels after ensuring antenna was properly attached?
