I have a Bush TV (IDLCD32TV16HD) which I have used successfully on SKY, BT Vision and Freesat. I now just want to use it on plain old digital but it will not connect/tune in. I have attached a freeview box to the same aerial lead and it works fine with that, but that's not the point! Anyone have any ideas on how to get the TV to recognise there is a digital signal to tune into. I have lost the manual too which doesn't help.
Many thanks

What do you mean by this ?
How are you trying to connecting and from what source ?
