We moved into a new house in Torbay about 6 months ago. There's a UHF aerial on the roof but it wasn't working (no signal detected) so I got an aerial specialist out. He said it was missing a power supply for the masthead amp (which the previous owners probably took with them by accident) so he installed a new one. Initially everything worked fine, but recently I noticed a lot of pixellation on any TVNZ channels (1, 2, 1+1, 2+1, Duke) and now those channels have stopped working at all - I just get a "No signal" message. All other "terrestrial" channels work fine.

 

This isn't a huge deal because I can still get those channels via the On-demand app, plus I don't watch a huge amount of broadcast TV. However, I'm keen to know what has likely gone wrong.

 

Before I pay a call-out charge for the aerial specialist, does anyone have any suggestions to troubleshoot?

 

Thanks,

 

Martin

Why not get the installer to come back. Clearly he didnt do something right.

Means nothings. Reception can change with the seasons, do you have line of sight, my guess is no.

If you want to troubleshoot then without a proper spectrum analyser about the only other choice is a ladder.

Not necessarily, there could be a number of reasons eg if it was wet he may not have gone on the roof.
He should probably have protected himself however by saying something like “ The signal is fine / marginal whatever, but as you haven’t used it I cant say how it will perform in various weather conditions

The installer replaced a missing masthead amplifier power supply. That doesn't make him responsible for every subsequent problem. If there's been bad weather the aerial may have twisted on the pole. If that happens when you have good reception take a picture that shows the aerial position in relation to the roof for future reference.

Try re-tuning?

Would a modern TV not auto-retune? I haven't tried, to be honest. Maybe I'll give that a go first. Thanks.

Many things could have gone wrong, those masthead amps don't last forever either
