I have a APEX 27" color TV. Recently I bought Altec Lansing XA3021 gaming speakers w/ sub for my multiple gaming systems. I placed both (supposed) magnetically shielded speakers on top of my TV...After about a week or so I noticed a purple haze on the screen right below my left speaker (the top left part of the screen); the right side was fine.
Is there any know why to remove this? Or is it permanent? I took the left one off and only the right one stays on the TV now.
