I’ve got an LG TV, had it about 4-5 years, very happy with it, although recently the DTV channels have been very weak, but we have Sky HD so tend to watch everything through that anyway.
locally to us there are a number of big billboard ads with “retune on Sept 7th” and “retune on Sept 21st”.
So I retuned on Sept 7th & the DTV channels are much stronger than they ever were before. There is an option to “lock” the channels which I tried on a few, didn’t seem to make much difference to the ones I hadn’t locked.
I’ll try again the 21st as the billboards suggest, but it’s looking promising
did you “save” the retuned channels?
