Trinitron Visual Phenomena

[zeno]

Most of what you see is probably normal & not really the
TV. Old sets dont handle the cable boxes etc well. You can
try turning down the brite & contrast & see if it does better.
The bow effect is usually pin cushion adj. On 70's sonys there
was a little cap that was a common fail. You may also have some Overscan
that may be related to the pin problem BUT its normal to adj a
set to have a little.You may want to put up a screen shot & maybe
we can see something else as it sounds hard to describe.....
