Lost all the TVNZ channels

[Skolink]

Are you on the Kapiti Coast? If so your channels have just been restacked.

A rescan should find the new frequency, assuming there isn't something interfering on that frequency eg an old VCR RF output if you have it looped through. 70% signal is a bit low actually. It's quite possible that the TVNZ signal is too weak, and the lower frequency it is now broadcast on is not as optimal for your antenna / signal path.

Do you have a decent UHF antenna?

Sorry, should have mentioned we are in Pukekohe, just south of Auckland.

I've no idea about our aerial to tell you the truth - it's just whatever was on the house when we bought it. Never had any issues, had Tivo about 2 years now and the TVNZ signal has always been fine.

Just perplexed how it can be decent for ages then die overnight.
