What causes pixelation only on digital 9 TV and there subsidiaries

Long story short, it is not your fault. Your provider will blame you, TNT, will blame your provider, and both are wrong.

The most likely cause is HD TNT is not a "real" HD channel. It is probably an SD recording TNT is upscaling from SD to HD. This can occasional create a dirty HD signal being broadcasted. Some TVs have trouble decoding this signal and end up with pixelated images because the image has been pre-stretched to fix the format.

Temporary solution would be to change the resolution of you TV for just the TNT channel. Some TV will let you select a preferred mode for a channel. If you can do this, set it to 720p instead of 1080p or try 1080i for TNT to see if this improves the image.

Also make sure that only one tuner is altering the images you are receiving if you have a FIOS box. If it is processing the image image in any way (color correct, resolution, etc.) turn those features off and let the TV do it.

1. Your TV has a digital tuner built-in, you do not need a set-top box to receive local digital channels.

2. Try to disconnect the box, hook up the antenna directly to the TV antenna input & program the tuner, you may getting better picture.

Pixelation is caused by poor signal strength. Check the signal strength in the setup section. Unfortunately some boxes and TVs don't handle poor signal as well as others. It might be worthwhile trying a signal amplifier

if the picture keeps breaking up and pixelating it is normally a reception issue rather than a problem with the tv.

The unit was being manufactured in the early to mid 2000's but I believe is not out of production. It is NOT an HDV. Here are the specs for the TV.

Usually a TV that pixelates only on some channels is a problem with the signal levels coming into the TV or the cable box. If you are using a cable box then definatley the signal is the issue..

Check the program playing menu see if in HD.
The HD should be slighly sharper images because in higher Pixels count mode.

The aspect ratio (zoom) button on the cable remote had been changed. On Brighthouse the # button toggles through the zoom settings. It's not a tv issue, it's a cable fix.

Is this a HD channel? This is usually caused by a hiccup in the streaming of HD from the cable/sat company. How long has this been happening?

This is caused by one thing, poor signal strength.
