Hi All

I have been having a problem(s) with watching Freeview on my tv.

Here is the current setup for watching freeview

have a Panasonic plasma tv(V10Z), connected to my antenna jackpoint on the wall via a $20 antenna cable.
I then use RCA out on the tv to my Yamaha receiver.

here is the problem
The TV will have squares flaring up from time to time (like playing a bad movie clip on computer) and entire frame frozen, same thing happens with the sound, this is particularly bad with TV1/TV2

how do I overcome this?

Cheers

Display: Panasonic P50V10Z

You will need to check your antenna orientation, and whether it has any corrosion. Also, you should check the cable from your wall jack to the antenna.

Has this been recently?

Ove the weekend 1,2,3,4 were really bad for me also, completely unwatchable at times. Fortunately the rugby was on Prime!

I thought it may have been the weather, as it has gotten better in the last day

For billions of years since the outset of time, every single one of your ancestors survived, every single person on your Mum and Dads side, successfully looked after and passed onto you life. What are the chances of that like?

The blocks/freezing you are seeing are definitely due to poor reception. This could either be from having the aerial pointed the wrong way/corroded/bad cabling from the aerial to the wall socket, or from not having a UHF aerial at all - a lot of places if you are close enough and have line of sight to the transmitter, you can pick up freeview using a VHF aerial, but this is not ideal.

How is your Analogue reception for UHF channels (like Prime, Juice)?

EDIT: Just saw your other replies - Is the other TV running freeview also?

thanks for the reply, the other tv is running freeview but with an external freeview box though.

but never had problem with that tv... thats why I didnt think the aerial were pointing the wrong way? maybe bad cabling from aerial to the socket?

Or from the splitter?
You must have a splitter installed somewhere (2 tvs off one aerial).
Could be a bad splitter too - is it a plug in one or does it use F-connectors (screw in)?

Hi, no idea about the splitter, but the aerial is a is a plug in type...

its funny now cos TVNZ channels(TV1 AND TV2) used to be good and no interference at all, TV3 has been unwatchable, but in the the last few days this has changed. TV3 is now ok and TVNZ channel has been unwatchable

Access the menu and choose 'Setup' then go 'Digital TV Tuning Menu', then 'Signal Condition'.

You will have two bars, Signal quality and strength.
Let us know what they read.
