Super neo 29" Cab with a discolored moniter corner

[lessthancj]

Greetings! I've had this cabinet for about 3 years now and everythings worked great. So I decided I want to put some work into it recently so I moved it into my room next to my two pcs and tv with consoles (it looks like i spend way too mcuh money on games here). Anyway when I booted up a PCB the top left corner is discolored red or green (not too big a spot) and there's a little discoloration on the bottom left too.   

Does anyone have any idea what this means or how I could fix it? Maybe I knocked something loose moving it? Kinda freaked me out when I thought the whole thing could be shot soon. D:

I can post some pics if that would be helpful.

It's not visible in the picture but a very small portion of the bottom is discolored green.

thats just some gaussing,what monitor do you have?
maybe you  have a push button degauss

it just needs degaussed; do you have any unsheilded speakers or anything near that corner?

Thanks grantspain and malenko, that's a huge relief! I had a speaker sitting up top below the light and forgot all about the degauss.
