I have a solo2 with open box and for the past few days, most of the FTA channels do not seem to work, I click on the channel and no picture comes up then a message appears saying 'tune failed' 'timeshift not possible'. Some of the FTA channels work but majority don't. I've done scans and it hasn't worked, could it be the lnb? I've switched the feeds on the box but that hasn't worked. 😩.
