I have had an Alba LCD22 for some time but have just replaced it for a larger screen. It had been set up to operate via Virgin Media. I am now trying to retune this in a separate room just to operate as freeview attached to an aerial. However when I switch on I am getting no signal and there seems to be no 'settings' box as indicated in the manual so that I can find out how to scan for channels. I have tried going back in its previous location but attached to the outside aerial alone but getting exactly the same response. Do you have any idea what I can do?
