Ok, so I've tried everything I can find on the website (unplugged and re-booted several times)
up until about last week cable box was working fine.
now it's acting up, usually when I reboot it it works after an attempt or two.
unplug it (have tried from 30 seconds to an hour before re-plugging it)
displays 'boot', often goes blank again after about 5 mins, and then starts with boot again.
finally when I get it to the app display, shows on screen that there is a problem accessing server, try re-booting or select another channel.
