We just recently moved and had the moving company store our small
color tv set. Now, when we plug it in to satellite tv there is a line
originating from the bottom of the screen and that horizontial line
scrolls all the way up the screen - this repeats over and over.
Somewhere in the dark reaches of my brain I seem to recall that this
could indicate a "tube" going out or having gone out? Suggestions?
Could it be the satellite install? I doubt that, but want other's
opinion.

Thanks in advance,

Lana

These articles describe the "hum bar" phenomenon:

They're on the techy side, though.

If you can't resolve your ground loop problem by reorganising your
cabling, the author suggests two possible solutions - a Video
Isolation Transformer or a Video Common-Mode Choke.
