In desperation to get my H7S to behave sensibly I tried restoring to factory defaults.
I found Tuner A (the only one I had connected a present) would not find any satellite signals.
Swapping the dish connection to Tuner B and changing the configuration to match resulted in signals being found.
I think my Tuner A has an intermittent fault.
This would explain why I was often frustrated by, I thought, often finding that the device was busy doing something, probably EPG related, of it's own making when I tried to use it.
Also it came with a notice not to remove the plastic scratch protectors until I was happy, but it was clear that they had already been removed and pressed loosely back on in a haphazard way such that they were half peeling off on their own.
What are my chances of getting world-of-satellite.co.uk to exchange the unit or will they insist I ignored the instructions to leave the plastic on?
