Don't spend your own money on cable and shielding. This is, indeed, a
problem internal to the monitor. Sony needs to get these monitors back from
you and confront some ee with the fact that his design was mistaken.
You might try carrying the monitor to a few different locations and seeing
if self test mode still displays the problem. This might help the Sony
people find the problem. They deserve help. They are treating you honestly
while trying to debug a design problem. I have seen a lot less candor from
others.
