I have a Premier Series 4, I use it for OTA only, today I lost a channel and went to the signal strength meter and it shows 0 for every channel. It shows digital signal acquired and I have a picture but no signal strength. Software version: 20.3.1-01-2-746
Also if I go to the diags screen it also says 0 and snr = 0 also
Also what does the service level mean? mine is C:070813
I never saw this before.
