Opening up TV cabinet to shield tv's internal speakers...should I do it?

Video Asylum

TVs, VCRs, DVD players, Home Theater systems and more.

I recently purchased a used 32" Hitachi tv for a spare room but have noticed that, probably due to the cabinet's flimsy construction, the tv's internal speakers (at the bottom of the tv) are creating small areas of magnetic interference (greenish-colored distortion) at the bottom corners of the tv screen. The problem is barely noticeable when watching DVDs (black bars at top and bottom hide the problem), but on regular tv it is annoying.
I suspect that the problem could be solved by opening up the tv cabinet and placing a layer of foil or other shielding in between the internal speakers and the tv screen. I'm thinking of enlisting the help of a friend who has some technical proficiency reparing stereo equipment and unscrewing the back of the tv cabinet from the front part to open it up and try to shield the speakers. But since I've never opened up a tv cabinet before, I was wondering if this is a wise idea. How difficult is it to open up a large tube tv cabinet, and what's in store for me once I do? Would I literally be opening up a Pandora's box which would be better left for a tv repairperson to deal with? Or is it pretty straightforward once the front and back cabinets are unscrewed? Thanks in advance.
