    I've got a situation where I've installed 3 separate CRT monitors, all JVC AV36F475's. They are in different locations throughout the space but ALL three are doing the same thing...

    Green ghosting over the screen.

    I know this is the result of some sort of interference (magnetic?) but I'm at a loss as to how to fix the problem. I've used an external degausser with temporary success, but the problem has returned.

    Does anyone have any ideas about other possible causes, or what might be creating a field strong enough to effect all the displays? Any ideas on how to fix this problem?

    Additionally, there are Sharp 37" LCD displays in the same space with no image problems. The place in question has industrial microwaves in use, so I'm wondering about them as well.

    Thanks for any help you can offer,

    Hello Dualline (welcome to the Forum :) )

    Could well be the industrial microwaves or other similar equipment nearby.

    The LCD screens won't be affected, unlike the CRT's. :lesson:

    Can you go over to LCD's only?

    Thanks for the welcome! I've bookmarked the site for future reading. :smashin:

    So, industrial microwaves can be problematic for CRT's?? I didn't know for sure. As far as a solution goes, I think the manufacturer wants to try a swap. I hope that works, 'cause in a 4:3 format I don't have many options in the 36" range. Sharp has a 37" LCD, but that's a 16:9 and the content is formatted specifically for 4:3. Nevermind that the Sharp unit blows the top right off the budget. ;->

    Thanks to everyone for the responses!

    Can you post some pictures? As your in the 'states this could be an NTSC problem,(although if it was you would expect the LCD to do it too)assuming they are all fed via the same signal??)

    Any strong magnetic feild will disrupt CRT sets PQ LCD/Plasma are immune..... 42" Plasmas are cheap enough these days and will happily run 4:3 modes.
