I have it working with other devices - a DVD player and an Apple TV. All working well there. The Humax does appear in the source list and is working okay if controlled by the Humax remote. It's also in my shortcut menu on the home bar. It's clearly not set up properly as I no longer get the options with it anymore - like 'guide', 'recordings' etc that I had before. Have tried deleting it and setting it up again but no joy.
When returning to the source list, there are two options 'edit' and 'Universal remote'. The remote option gives the option to start setting it up. I select cable/satellite box, confirm it is connected to the TV directly (not via a home theatre system). Asks for postcode, which I input, asks for service provider (Freeview play for my region), next my TV service provider (Humax). Asks to confirm TV source (HDMI1), then the options to test the remote (channel up/channel down and confirm if it changed channels) - it doesn't right up to the final 20th attempt. Search model number comes up. Select manufacturer (Humax), but not of the options coming up are for FVP-5000t. Nearest is FVP-4000t. That doesn't work and nor do any of the other options. When it did work previously it just worked without getting to the model number stage. I'm a bit stuck here.
The TV is connected fine to the router (it's a wired connection), internet services working okay. FVP... powered on - not sure what you mean by mode 1. Are you able to elaborate?
Thanks for your help.
