Lost my freeview channels and retune not resolved
I'm having some problems with my new LG TV, it isn't picking up half the channels it should be.
I've had a brand new aerial recently installed and that seems to be working fine - I have a second TV in my house and that is picking up channels ok, so can't see any problems there.
The LG TV was working fine yesterday evening, then all of a sudden said 'no signal' on the TV guide and all my channels seem to have been wiped.
I have tried an auto search for the channels, but to no avail. It brings some through but not all. This includes terrestrial channels 1 and 2. I have also tried leaving it off a while, but again not helped.
Pretty please can someone help me - any advice would be much appreciated!
