If I could smack myself, I would

I installed an "UN-SHIELDED" 6" speakers in my cabinet under the marquee shelf. I didn't even know I had to worry if speakers were shielded or not! Well, to make a long story short, I turned on my monitor and there is a Pulply-Orangy defect on the left side of the monitor. Kinda like there was a magnet in front of that area of the screen. I hit the degause button like 20 times and nothing happened. I left the monitor alone for a couple of weeks and degaused again and still no luck

It is my 19" monitor. I will hate to have to toss this thing. Anyone have any ideas PLEASE???
Not sure, should I be posting this type of question in Monitor/Video section?
Thanks,
Garry
