Irritating problem to have....

I'm thinking about ditching Sky as I really don't watch broadcast tv as much as I used to. My tv is a 2.5 year old Samsung. I originally setup Freeview no worries when I bought the TV but have not used the Freeview function at all since. But I still expected (perhaps naively) that it would still be setup with all channels in the correct order as they were when I first set it up.

However as of now, TV1 and TV2 (and their +1 counterparts) are nowhere to be found. A bit odd I thought as they were definitely there when I set it up. No worries I thought, I'll just do a channel re-scan.

The channels I do have are Three, Bravo, Eden, Bravo+1, Three+1, Rush, HTV, Al Jazeera, Trackside 1/2, Shine, Hope, Radio NZ. Not sure which other channels I'm missing, but it's really only 1 and 2 that I would like.

Have so far attempted multiple manual and auto channel scans but cannot for the life of me find TV1 and 2 (or the +1's). Anyone know what the heck is going on? I'm in Christchurch with line of sight to Sugarloaf. The terrestrial tuner is obviously working as I have all the other channels as above.

It's a Samsung QA65QN90AASXNZ purchased at the start of 2022.

I've tried googling my specific issue but haven't found any solution yet. No advice on the Freeview website beyond what I've already tried, and same with the Samsung support pages. I'm hoping someone on here has had the same issue and found a way of solving it.

Has your aerial rotated on its mount?

I wouldn't have thought so but will check it at the weekend. All other channels have a perfect picture and they all come from the same transmission tower so it would seem strange that only a couple of channels would be affected.

In any case, I just discovered that I have the Freeview streaming app on my TV, which does give me TV 1 and 2, so that is a potential solution if I can't work out the root cause of the terrestrial reception issue. It's still annoying if it turns out to be some limitation or issue with my tv given it's young age.

Something to note, believe as of yet the streaming versions are still max 720p

And if you have a soundbar or audio system. No 5.1 either.

I get to see appleTVs version and the broadcast still eats it for breakfast. On a 4k/upscaling panel it's a better start point.

AFAIK groups of channels use different frequencies The one used by TVNZ may have more loss from misalignment so they've dropped out.

Yep,

Sounds like you're missing the TVNZ MUX (so, TVNZ 1, 2, 1+1, 2+1, Duke and Duke +1).

Check Aerial and cables - it may only be something really small. From memory, the TVNZ mux is quite sensitive (lowest frequency). I think on ours when the reception drops off a bit (our antenna is pretty marginal) we lose the TVNZ channels first.

Could also be local interference causing issues. Now that there is 700MHz cellular, there is a much better chance of cross modulation in crappy antenna amplifiers making that have a product ontop of one of the DVB carriers.

If you have an amplifier, try bypassing it. If that makes it appear then you want to get a LTE filter for it.

I have a Samsung tv purchased few years ago and works perfectly 99% time , think my aerial is a bit off done multiple scans and no change, when there is wet or windy weather all my tv 1 & 2 and duke and plus 1 channels stop working with message no signal. When this happens I just use TVNZ app to watch which is fine and tv3 and other channels all work good from aerial. I'm in Auckland city and think it definitely is aerial gone askew just not had time to get it fixed, and happy to use apps when needed but if I lost all channels then would need to get it realigned.

This is at a friend's house. When the reflector doesn't line up with edge of roof we know it's moving and channels will disappear.

When you get it right take a picture as a reference.

Sugarloaf is horizontal. If that's in Christchurch, it's a wonder it works at all.

It's just an example pointing at Wharite Peak near Palmerston North. That's only 60km vs over 400km to Sugarloaf.

Kordia/WTV mux is at bottom of stack on channel 28 (526 to 534 MHz). Channels to note on there are Trackside 1/2. Can you get Trackside on LCN 23, 24?? TVNZ mux is channel 34 (574 to 582 MHz). Top of stack is MTS on channel 38 (606 to 614 MHz). Can you get Maori TV on LCN 5??

Spark Max Fibre using Mikrotik CCR1009-8G-1S-1S+, CRS125-24G-1S, Unifi UAP, U6-Pro, UAP-AC-M-Pro, Apple TV 4K (2022), Apple TV 4K (2017), iPad Air 1st gen, iPad Air 4th gen, iPhone 13, SkyNZ3151 (the white box). If it doesn't move then it's data cabled.

I've got the Trackside channels on 23 and 24, but don't have the Maori channel. I listed the channels I can see in my OP if that helps.

I haven't had a chance to check the antenna as I was busy yesterday and the weather is crap today so too lazy to pull the ladder out in the rain.

Samsung TVs have signal information, Settings/Support/Self Diagnosis. I'm in Belfast and get 100% quality on all, signal strength greater than 90% on all split 4 ways. So if you have marginal quality on any channels then definitely an antenna problem.
