I have a sony 40 inches bravia flat screen hd and

Could be the decoder:

1. unplug the TV ans wait a few mins.
2. If you have digital cable box or dish tuner reboot those as well (likely your issue)

What you have is artifacting what that means is tiling garbiling and freezing this happends when the data in the digital stream just stopped hence Frozen.

Try those things rule out your cable tv box first or your sat box, if this is OTA over the air your antenna.

1. Try DVD's if it happends during a DVD you do have a decoder issue if it does not you need to talk to your cable tv or sat operator.

So you got 3 possiabilites here 1. the worse Decoder, 2 cable company or satalite provider, 3 your antenna is in the wroung position.

I sure this will help.
