Hi guys,

I just bought a Freeview HD DSE box. I can every other channel crystal clear but when I turn on a TVNZ channel (TV One/7/6/2 etc.) I get a 'No Input' signal and after a while it does show up but it is really blocky and the sound cuts in and out. Why can I get the other ones with no problems but not these?

Thanks a lot for the help!
Max

Where are you you located and what type of aerial are you using?

sbiddle: Where are you you located and what type of aerial are you using?


And are you in a multi-dwelling complex with a shared aerial?

I live in Remuera. I'm not in a multi-dwelling complex but I do have these aerial connection points in the walls all throughout the house.

There could be an amplifier in the box on the pole that was formally powered by a plugpack that the installer would have taken with them when you got the sky dish installed. If thats the case then there will be minimal UHF signal available.

Many people have reported this same issue (including myself).  Some days the signal is perfect, then others it is so bad it is unwatchable.  There seems no apparent reason for this (weather etc).

Most people here ask the same old questions like the multi-dwelling and aerial type ones.  But no one has ever suggested that it is a broadcast issue.  It is hard to believe this might be true, but there seems no rhyme nor reason otherwise.  Damn frustrating at best...

I couldn't see in the above posts which transmitter you are pointing your UHF aerial at.  Obviously not Waiatarua if that is what your VHF aerial is pointed at.
Question for someone like Cyril, Does it matter if the UHF aerial is horizontal or vertical, or is that only an LNB thing?

is freeviewHD really that troublesome, today i have problems with channels3 & C4. I don't want anymore unexpected crashes since my tv is freeviewHd built in.

i want to know if this is the freeview's fault or my antennas fault, since i've been hearing so many different things...

Your antenna systems fault, DVB-T installs need to meet minimum specs re: cabling, shielded splitters etc. and the antenna position needs to be determined correctly using the appropriate hardware to measure bit error rate and carrier to noise.

Thanks for the replies guys. I might go up on the roof and check out the box etc. to see if everything is as it should be. Interesting enough I can get TVNZ channels on the standard connection direct to the TV without going through the Freeview box but not the other way round.

Cheers,
Max
