Any reason why box on booting up goes straight to blue screen mainteance mode?
@Archie1971 That shouldn't be happening, I'd recommend you report the issue to the BT TV helpdesk for further investigation.
I am a BT employee and will investigate your issue. Are you able to PM me your telephone number so I can investigate further.
Sounds like a hardware failure on the set top box.
Look forward to hearing from you.
