I received a new box yesterday and installed it myself which was fairly straightforward. However, when starting up, it is stuck on the "starting up checklist screen". Everything is "ticked" aside from the last bit which is "checking network connection" or something like that. I have turned everything off and on, checked the cables, sockets etc. The internet is working fine, but the TV just keeps getting stuck on this screen. I really didn't want to have to get an engineer out as it seems unnecessary having the correct kit in my house. Has anyone else had a similar problem, or does anyone know of a fix? I did see someone previously post that they turned the Tivo box off, waited 15 mins and then it worked. Tried that with no success. Any help would be much appreciated!
