I have just purchased a new JVC 32" flat screen. Since the Forte I's that I have are older speakers, they are not sheilded thus giving me probems with the screen. This is confirmed by moving the speakers away (and I mean far away) from the TV to make the spots go away. How can I solve this? Is there a way to sheild these magnets? Do all the magnets need sheilding, or is it the cabinet that needs to be sheilded?
