Hello , my name is Jack Perhaps I can help you with this problem .
From your description you have accidentally switched the tv to TV/antenna mode .
In other words you changed the input and need to get back to the input where the youview box is connected .
Look on the tv`s own remote for a button called INPUT or SOURCE and press it repeatedly until it gets back to the correct input.
If that answers your question please do not forget to rate or you can use the reply button before or after rating if you have other questions and if not then please let me have the tv`s model number written on the back cover, thank you .
I had tried that but all i get is that " No channels have been added yet.Please go to Install and reune menu to add channels" I have done this time and time again to no avail.
Right the tv is a Toshiba 32D1334db LED backlight LCD tV. The ariel is is in the HDMI 1 socket.
It is carried through a bT extender box.
Does this help? Please advise
Oh really, I was using source and then pressing TV not HMDI ......
Stupid or what > I have turned it to HMDI and it is working.
Thank you for your help. Sorry to have disturbed you.
