Digital signals do not fade out and get snowy like signals used to do ... if the signal gets too weak then it just freezes .. you might say its either perfect or frozen .. sometimes it gets blocky .. where some sections of the screen freeze while other sections continue .. what that means if you are using an antenna is .. you need a better antenna or better aim for the one you have .. outside is much better than inside but just rabbit ears are ok for strong signal areas .. you can aim the antenna based on a signal strength meter usually provided in HD receivers in the setup menu .. you can also get an antenna map from "www.antennaweb.org" .. that will show you what direction to point the thing for each channel and how strong each channel should be ... if you are using Cable instead of an antenna then you should have good signal strength but there is a problem called "Crest Factor" .. that becomes an issue when they put too many signals on a given cable .. the cable handles it ok as long as there is no damage (bad ends, water inside, animal chews, corrosion) but the cable box or receiver may be overloaded as thousands of signals drift in and out of phase ... thats a cable company problem that might be getting worse as more channels are added .. the results are that periodically the picture will freeze or pixelate .. you probably have to accept a little of that but more than a little gets really irritating ....off the air reception with an inside antenna (like rabbit ears) you will find that moving around the room can effect the signal for channels in the UHF range (most are) .. aiming the antenna and getting it as high as possible will minimize that problem.. make sure whatever antenna you use is designed for UHF as well as VHF .. the little circle often found between the two "rabbit ears" is actually the UHF part of the antenna .. it can be rotated for UHF channels while the big ears are aimed and adjusted for VHF .. antennaweb.org will tell you which is UHF and VHF ..

I no idea how I got this question I have not got a HD TV let alone smart. Is the format compatible on them both ?.I can not help apart from that sorry .??
Digital TV uses less airspace than analogue TV, so after the digital switchover there'll also be more room for services such as high-speed mobile broadband and high-definition television (HD TV).
There is a few issues that can result in picture freezing 1: Overheating, keep it in a open area away from other devices 2: Your coax line from the cable company is going bad, if the rest of your TV's in your house are ok then its the one line itself going to that box, it could be an older 59 line or the fitting on the line needs to be changed.
I would suggest to leave your directtv hd/dvr box connected the way It is.
The HD Colorstream 1input on your TV should work just fine.
This TV does not have an HDMI input but you can buy an adapter and connect to DVI/HDCP IN and that might be able to get 1080i video resolution on your TV.
You are suffering from a poor signal. Digital TVs will display 'blocking' (partial freezing of the picture in square or rectangular blocks) or total freezing of the picture, when the signal is too weak.
You don't say if this is a recent problem on a set that has been working correctly - that info. would be helpful. However, things to check include:
Has the aerial moved (wind?)
Are you using a new extension coax cable? If so try another one, as connections may be faulty.
If this a new TV, and you have not used digital previously, your aerial may not be high enough gain for a digital signal, but that is unlikely unless it's a nery old aerial.
