Any CRT experts? Decased a 32" Sony Wega Trinitron for arcade

mgb- Thanks for the input!  I've got a second CRT lying around that will eventually be a cocktail cab, so hopefully I'll get more than one use out of that degaussing coil.  Fingers crossed that it solves the color issues!

Gray_Area- The decased CRT weighs 165+ lbs... There was absolutely no way I was going to be able to safely move/mount this thing directly into a cab without hurting myself or breaking something.  The wooden frame solution keeps all of the CRT components from getting damaged while being maneuvered, keeps humans safe by keeping hands and fingers away from any potentially dangerous areas, and makes it so I can just remove a couple of screws to slide the entire thing it in and out of the cabinet if I ever need to work on it.  The cabinet I've designed has more than enough space to accommodate the frame, so while this setup may not be typical in regards to mounting it should work great (assuming that I get the color issues sorted out.)

After degaussing, be sure to move the coil far enough away from the monitor before you switch the power off.

I've seen guys make the problems worse by shutting off the power to the coil while the alternating magnetic field is too close to the monitor -- accidently leaving the monitor magnetized.     :lol

My guess would be that in the upward position it gets closer to something that is interfering, like speakers/electronics/harddrive etc.
Try to move around the other internals and see if it helps.

PL1- Thanks!  I've been trying to watch some Youtube vids and I think I have the basic idea down, but I appreciate the tips.  Would it be really bad for the TV if the scenario you described actually happened, or could I just start degaussing over again and fix it?

matsadona- I was wondering that too... I've removed the speakers and only moved the electronics for the tv by 2" or so (but the movement did bring everything slightly closer to the back of the TV)... I'm not trying to use it with the computer yet so really the only electronics it is close to are its own internals.  If the degaussing coil doesn't fix it I've gotta assume that the location of the CRT electronics is the problem.

Here's an image of the screen... all the green is supposed to be red so as you can see the discoloration is very pronounced.

You could just start over again.

The coil is producing a magnetic field that alternates North and South pole orientations.

You have to get close enough to overcome whatever magnetization currently exists.

By slowly moving further away, the strength of the magnetic field reaching the monitor slowly decreases until it's too weak to magnetize the monitor.

The only thing you couldn't undo is if you get too near the HDD or your credit cards.   :hissy:
