We have just upgraded to the Ooomph package as well as getting a 3rd box. We already had the Tivo box in our bedroom and a V6 in the Lounge. We now have another V6 in the bedroom and an engineer moved the Tivo to our daughters room. He was running behind and I said I would set up the Tivo box. It switch on OK but I forgot to put the COAX in the back, only realised when it was on Start-Up for 20 minutes. I switched the box off, screwed in the coax and now the Tivo will not switch on. No lights on the front but there is a green light on PS. I have unplugged it for 20 secs and tried again as well as leaving unplugged for 5 minutes. Either way the Tivo will not switch on, no lights at all. The switch is on at the back as well. Have I missed something I can do before I call VM?
