Hi.
The modern tuners are bad for this. It usually means you do not have enough signal. You need to improve the signal level.

I have a freeview build into my tv which is Panasonic plasms tv Model no. TH-46PZ8BA and wish to know how I can receive HD channels BBC or ITV. Please advice and help.


HD Ready just means the tv can display HD images from an HD source.

The built-in Freeview box on your tv is not Freeview HD compatible so you'll either have to buy a separate external Freeview HD box or subscribe to an HD satellite or cable service.

In any case, most built in Freeview receivers are of barely adequate picture and reception quality. An external box is usually far better in both respects.

HD channel picture is clear, but regular digital picture scramble


o.k. check all your connections
if you have a newer house check to see if you have a main hub in a closet somewhere and check all connections. Check your hd receiver and you may be able to chage the DPI the receiver receives in.

I have this problem on some of my non HD channels, also. So much for going digital. I get fuzz and pixel problems "from time to time", but, if it is really bad and consistent your should call your service provider.

Things to ask also ? are you using cable or satellite.

If satellite T.V. there are other reasons you could be experiencing problems.

hope this helps!

Am i getting hdtv with just cable feed?


Depending on your cable provider, some of the HD channels may be present. If so, these are ususally located in the upper channel numbers. It sounds like you are receiving some of the HD lineup. A cable box will probably allow you to view more HD channels including the premium HD channels if you subscribe to them. You should not be noticing a delay with the HD channels only. If this is what you are experiencing without a cable box, then it would be an issue with the HD tuner built into your TV set. LG customer service can let you know if there are any software updates available for yourmodel that can resolve this. Additionally, if you are getting your sound from an Home Theater system then you will notice an echo if using the TV's built in speakers at the same time. This is sometimes mistaken as an audio delay. If you are using a home theater system, be sure to disable the speakers that are built into your system.

RCA D56W20 picture problems


More information is required to properly troubleshoot this problem. How is your television connected when you are watching HD? Do you have HDMI for this, do you have a satellite or digital cable box? For analogue are you using regular coax antenna (cable TV), or are you going through a cable or satellite box?
This could be related to the aspect ration setting. perhaps you ahve changed your aspect ratio from 16:9 to 4:3 or some other setting. If you are connected via HDMI, then the digital signal may be "normalizing" your picture during HD, but reverting back to the other setting.

Check you video settings very carefully. HD televisions are very difficult to tweak properly.

Grainy picture


Greetings israelmaker,

In order to receive true high definition television, you will need a high definition cable box. Basic channels are going to look more grainy and not as clear overall even with an HD box, however you won't be able to view or decode the actual HD channels without a box.

In addtion, what type of cables are you using to hook up your existing box? This can have a substantial impact on the picture you see.

I hope some of this helps.
