Simple tests to find where the fault is:
1 - get a home antenna (an old style passive rabbit ears) and plug it in.
2 - get an RF signal from a dvd player thru to the antenna conector .
If you get even the faintest signal or an image then the tv is good and the problem is in your present antenna and all the other amplifiers attached to it. 
If you don't get an image then try another tv of whatever type with all the available sources: your antenna, home antenna and the dvd player. If you get an image now then the tuner in the tv has been fried - replace it.

Have a Panasonic TH-37PX60U tv - can I hook it up to a HD Satellite receiver - have a Bell hd but don't get any reception


Your plasma tv will display HD content when you connect an HD source (Blu Ray Disk, Sony PS3 / PS4 or Xbox 360, HD Cable Box, HD satellite, etc) via the TV's HDMI1, HDMI2, Component1, Component2 jacks or if you connect a UHF/VHF TV antenna (not cable box, etc.) to the "Ant" connector *and* you're close enough to a broadcaster with HD content to view.

Using any other input will produce only the lesser quality SD video signals. Review the manual - linked below - to help you connect the components you have.

How do I get my tv to display full screen?


Depends on what you are doing. Sometimes the "full screen" is dependent on the signal coming into the TV from a cable box. Check the setup or menu function on both the TV and whatever input signal you are using. You didn't say what TV and what source i.e. cable supplier, antenna etc. Remember that an HD tv doesn't always display a non-HD picture in full screen.

You have antenna issues. Try raising the antenna some more or relocating to another spot where the signal strength is greater. Pixelation is a sign of a weak signal -
