On pressing the talktalk button on my remote control it goes to a grey screen with the error message ttg-954.
Does anyone know what this is
Information from TT help pages http://help2.talktalk.co.uk/talktalk-player-error-codes if you have tried this and the error persists then the OCE will assist you.
Are you using the TalkTalk supplied router? Are you using any Powerline adapters? Have you tried rebooting the YouView Box?
