Television and Home Theater

I have a set I have been using for quite a while on cable.

 I now want to move it to another site, which does not have cable.  However, I can't seem to get it to respond.  When I turn it on, it gets one channel with a lot of snow.

 I tried to access menu, but it won't do it.

Any suggestions?

 Feel free to respond to me at [email protected]

Can any of the members please help me as i have just bought the Satellite receiver and am having difficulty setting it up to receive programs.

Our 25" Magnovox (Model #HD2505 C101) recently started becoming distorted at the top and bottom of the screen, especially during brighter scenes.  It's been getting worse over the past few days.  The brighter the scene, the more distortion covers the screen.  I've tried adjusting the brightness, picture, sharpness, everything, but nothing seems to help.

Is my TV finally dying?

Thanks!
