Ever since I purchased this TV I had problems with installing Sky, now sinces thats solved I now have a new problem, which is the fuzzy picture I get on freeview channels 3 & C4 (channel 2 was abit fuzzy yesterday and also a little fuzzy for a little while today but right now is all good). I viewed the channels (3 & C4) and go to technical settings -> signal/channel info, the signal keeps changing randomly (poor, high and no signal). I get a feeling its not the antenna's fault, since the other freeview channels including 1&2 are clear and Sky.

I've resetted all the settings including factory settings.

This TV is a floor stock, its been used to display in Noel Leeming for around a month, its a Sony Bravia - FreeviewHD built in - Full HD 1080 and the model number is kdl40w400

Now I don't know if its the TV's fault or my antenna or maybe how I'm setting up everything, heres how my TV and equipment are set up:

[   ] ->TV
----
 == -> CD player
----
 == ->Sky box
 == ->VCR machine
----


(--- represents board/table)

Here is a link to the TV description:
http://www.sony.co.nz/bravia/product/bravia-with-freeview/current-range/kdl40w4000.jsp

If its the antenna's fault could somebody introduce me to a good technican that doesn't charge alot.

My older Tv (5 years old approx) was just removed yesterday and it had no problems with signal, it still broght clear picture.

The TV cost alot and I want to keep it, so it would mean alot if someone could give me a solution to this picture problem

I found a topic here pretty much related to my problem:
http://www.geekzone.co.nz/forums.asp?forumid=83&topicid=26690
He mentions he is experiencing issues with the TVNZ Freeview HD channels, but that topic was on the 29 - Sep -08, does freeview Hd channels always have these sort of problems?

Given your old TV couldn't even receive DVB-T H.264 I'm not quite sure as to why you are using that as a reception reference for DVB-T. If your Sky install is digital then the signal doesn't even come from the UHF antenna so more illogical conclusions.

I guess i should learn more about this 'freeviewhd' and 'DVB-T H.264 '

anyways the sky receives picture through satilite, i don't know much about the TV all i do is plug in the black cable with the round end which is connected to my vrc to play tv....i guess sometimes freeviewHD channels is abit glimpy from what i herd looking all over the net.

oh well atleast i can still get a ps3 for $100

You more than likely need a new TV aerial or the current one looked at.

What sort of aerial do you have at present? Where in NZ are you located?

You need a UHF Aerial pointed at Te Aroha or the hamilton infill (not recommended, te aroha is stronger).
If you want to know what one looks like, simply google images UHF Aerial and then check your own roof.

Also try connecting the antenna directly to the TV, not via the VCR - how things are connected matters more then what shelves they are stored on.

Do you have Sky digital ie via a sattelite dish? If so it should be connjected to the TV via component (or S-video if you have an older decoder). You VCR should be connected via composite video cables rather than RF. Split the aerial input if you must but you could just connect a sky composite output to the VCR.

If you have an old UHF sky box upgrade to digital!

For Freeview HD you need a UHF aerial. It is this you should commect directly to the TV.

If none of this makes sense you may have to pay someone who knows what they are doing....

when we first purchased sky a guy installed a satilite dish onto our roof (so I guess i do have digital sky), the satilite dish is next to the antenna, if by what u means a UHF areial, something thats shaped like an arrow then yes i do have an UHF areial but it looks kinda rusty maybe thats the cause of problem (glitchy picture)? FreeviewHD shows crystal clear picture at times but sometimes its really glitchy like yesterday from 11am-6pm and today 11am-2pm. It seems the channels are clear whn its evening and night time.

If i knew how to upload pictures then i could show u. Maybe I need to change the UHF areial (the Sony TV is a 2008 model and we purchased it as a 'floor stock' I keep thinking its not the TV's fault, I don't know)

I read the manual if you have picture problems check ur antenna if its pointed at the right direction or if its rusty.

If the antenna straight into the tv doesnt work, then you know its the antenna thats screwed... If its fine then its something you are looping the signal thru messing it up. Its easy for a crap amplifier to mess up a digital signal, and those rubbish modulators in vcrs and sky boxes are about as bad as amplifiers come.

Does your aerial look somewhat like this? This is what a UHF antenna looks like.

Do all sky digital decoders have component/s-video output? The only output on mine is composite, which looks really horrible on my TV.

It is via the Scart outputs so you need a Scart to Component or Scart to S-Video cable. No not all decoders output Component but all do S-Video. The easiest way to see if yours does is to see if the option is available in the Setup Menu. IIRC Component is only available on the TV Scart output. If your decoder doesn't do it you can have it swapped but you will have to pay a callout fee. If you do that tell them to supply a Scart to Component cable too.

yup, i see something shaped like that on my roof, ill try connecting the cable straight to my tv and see how its goes, it seems the glitchy picture problem only happens on the mornings (freeview channels 2,3,4 &7)
