Tv Set Up

[muskox]

Have a Toshiba TV and freeview box linked together, which have been working well. Am using a one for all remote control and I know how to find my unique TV code in which to operate it and switch the screen on. Must have pressed something, as all I can get on screen now is a DVD screen and not live TV. Have tried fiddling with all the knobs on the remote control and on the side of the TV, but to no avail.
Went on the menu and found AV1 and AV2 in case this helped, but I can not get this to register. I keep pressing OK, but it will not register. Have tried switching the machines off at the wall and starting again

Can you try it with the remote control that came with the TV, instead of the replacement remote control?
