We had a couple of power outages in quick succession today, and now
the display on our Philips/Magnavox TR2502 TV looks as if it has been
magnified by about 30% or so, and shifted slighly downward. The
effect looks something like what you might get with a DVD player that
permitted "zooming" in on a portion of the image -- all the
information on the peripheries of the broadcast is cut off now, and
the remaining visible area is clearly magnified. Otherwise, the
tuner, sound, etc. seem to be functioning properly.

Any idea what might be causing this? Suggestions for repair?
(Incidentally, the TV does not have a zoom feature!)

Thank you
