Tuner failed

Hi
My VUsolo2 4k
Keeps saying tuner failed
Is it possible to take out tuner A
and put tuner B into tuner A slot
I do not use tuner B
Or is there a way to bypass tuner A
Thanks Oxigen 1

I can't see a VU+ Solo 2 4K, on their website, is it a VU+ Solo 2, or VU+ Solo 4K?
Which image are you running?
Have you tried re-flashing, the image, and seeing if Tuner A is then working?
How have you get your tuner settings configured?
Why not just plug your LNB into Tuner B and change your tuner settings accordingly?

Does it say 'tuner failed' or does it actually say 'tune failed' ?
What image and image version are you using ?
More likely to be your settings are old/wrong than the tuner at fault
