Military radar Wi-Fi interference on LCD panel?

Hi all. New member here, so apologies up front if this post is misplaced or a repetition. I have searched the forum, but my problem is about suspected Wi-Fi interference and there are a million posts about that.

This might not be the usual kind of interference though.

I just bought an Inspiron 9100, and obviously I love it. So I was deeply dismayed when yesterday the LCD panel started flickering different colours and the objects/text on screen were slightly distorted and blurred. I did what I could - reinstalled the graphics driver, ran Dell diags, System Restore... no luck, and I finally had to concede that it was probably hardware failure and I'd have to send it back to base.

At my lowest point, with the LCD panel flickering away before me (remember how the screen used to look when loading a game on your old Spectrum computer... UK only perhaps), my attention was drawn to two WWII warplanes doing loops over the small airfield right next door... and then I remembered the 9100 has a (dual band) Wi-Fi card installed (do these things have aerials, and are they mounted inside the LCD casing...???) I have heard that Wi-Fi and military radar don't mix. To reinforce my suspicions, the interference ceased after the air display ended and the LCD panel has been good as new since.

So my question is: how likely is it that the vintage warplanes caused some kind of radio interference which manifested itself on my LCD panel? Or do I have a different problem that may return and requires service?

Thanks for any help. I appreciate you lending your experience here.
