Hi uzulu,
Silly as it may seem, are you sure you've got the correct source settings on the TV, and that you've tried a different HDMI cable and port (just in case) and rebooted the V6 when changing the HDMI.
If you do call Faults again, hopefully the system will recognise that you've used the online faults checker, and already spoken to them and place you into a queue for an agent to pick up.
If not and you get the automated response asking you to press 1 for the link to online support etc, ignore all the options and don't press any buttons then you should be placed into a queue and an agent should pick up the phone and resolve the problem.
Be firm with them, advise them of the tests you've performed and explain there are no lights but the box is humming.
