    Someone in my family accidentally placed a strong magnet on my CRT monitor. now there is a rather large discolored area on the screen. I tried to use the degauss function of my monitor but that did not help. How can I correct this and why does this happen in the first place?

    Here's a link I found on google, with a video tutorial of how to fix this problem...

    Also a local TV repair store, or appliance store, maybe even a PC shop can help you, they will have a tool that will degauss your monitor with a more powerful coil then the onei n your monitor...


    As for why magnets do this to CRT's, it's because
    The way CRT's work is that a beam of electrons are "shot" onto the screen electromagnetically, a magnet changes the magnetic field, and changes the proper dispersion of electrons...

    You have to fix the magnetic field. I heard they are cheap tricks to do that.

    Let the monitor rest for a while, it should restore all by itself. If it doesn't, go with it to an electronics store and send the bill to the family member!
