Tune failed

[luffy]

Hey, since yesterday i've been receiving this "Tune failed" error message when I try and watch certain channels. I checked my signal and both A and B seem to be fine, they both show the checkbox on the lock and have good signal strength.

I've reset the box, did a USB upgrade of the firmware, however I'm still getting this issue.

I'm currently running a scan for channels and will post a screenshot when it's complete. But I did do one yesterday and the channels i'm having issues with still showed up when it was completed.

I'm a bit baffled as to what could be the problem and hoping someone knows what I can do to resolve it.

Screenshots of what i'm trying to explain.

As always, thanks in advance for any help provided, I appreciate it.
