My tvdon work still

yap! for CRT TVs with ring of colors, do the following to solve the problem; find a normal magnet from a retired speaker , just switch on the TV and while the TV is On, hold the magnet about 15CM from the screen while moving it arround the whole screen area. when it starts to degause/to be clear just move the magnet around the screen while moving further away from the TV screen let say 20CM, 25CM , 35 cm etc.

To fix this, you need to do something called degaussing. You should keep magnets away from the screen in the future, because they cause this problem.
The first thing to try is to turn it on and off, making sure that all magnets and speakers (which have magnets in them) are kept far away from it. This will activate the monitor's auto-degausser if it has one. If this does not help, this guide: http://www.wikihow.com/Degauss-a-Computer-Monitor gives a couple solutions, including using a soldering gun (not a soldering iron), illustrated in the video below:
With a powerdrill:

Or investing about 60 bucks in a degaussing coil like this which is a guaranteed fix:
One other trick that might work is to take an old CRT monitor ("fat-screen" rather than "flat-screen"), hold it up to the tv screen to screen, and turn it on and off to have the monitor use its own degausser. The monitor may have a button to activate degaussing, or it may be in the menu you can bring up with the buttons on the bottom of the screen.
If you don't want to deal with any of this, a tv repair shop will degauss your tv for you quickly.

What you want to do is degauss the tube.
I do not believe a supplier will sell a CRT to anyone thats not a TV Tech. Safety/liability issues. The CRT is vacuum sealed and will implode if broken and the tv has 25000 volts even after unplugged for several days !!!
A CRT may cost as much as a new tv.

Several methods some people have found useful are;

Soldering Gun Method (NOT soldering iron)

1. Hold the soldering gun to that the rear of the case is toward the screen (the tip is facing away from the screen at a 90 degree angle) A magnetic field is generated by the transformer in the handle.
2. Place the gun in the center of the screen and turn it on, keeping it near but not touching the screen (to prevent scratching)
3. Slowly move it to the top edge (or any edge), then slowly around the outer part of the screen (but still in front of the glass) until you return to the top (or the edge you moved out to), again slowly return the gun to the center of the screen.
4. Keeping the gun on, slowly pull it straight away from the crt until there is no more distortion visible (usually 3-4 feet), then turn the gun off.

Rigged Drill Method ( parts can fly off so take care)

1. Get a magnet and tape it to the end of a high RPM drill and make sure it is held in place very tightly, use Duct or packing tape
2. Hold the rigged drill next to the spot to be fixed, make sure it is about 1-2 inches away from the screen
3. Now pull the trigger an you'll see the screen blur fast, this is normal so do not worry
4. Whilst the drill is running, slowly pull away from the screen and you may see it is fixed
5. This process may need to be repeated due to magnet strength and drill speed but it will work
6. Due to physics the fast, random turning of the magnet/s will fix the screen's colors

make a degosing coil or try to look for a website how to make it in the phillipine we only make it coz we can't buy or its not available in the marker ok thanks that is the only solution you can do k
about akai tv may be it just coldsolder in crt socket try to solder it thanks inform me

there is a small magnet in the lcd housing underneath the camera cable that may not be in.

actually your tv set was placed near object produced magnet especially speakers, used magnet, small one to de-gauss or just like cleaning the the tv screen untill impurity colors gone. need my [email protected]

ahh, that isnt good, the only reason I can say, is, the green stain your referring to, is result of a magnet, or magnetized object coming too close to the screen, thus pulling the color from the screen, depending at which point you put the magnet, it will either be green, red or blue. I dont believe there is fix for it.

i guess its the old magnet problem maybe in fluke u or someone in your house had taken a magnet around your tv try fixing it with a magnet by moving the magnet again around the screen and using the same old technique by moving the magnet slowly on the defected area and then quickly taking it off

maybe UFO around.. just kidding the mask in your picture tube may be damaged if that set is drop by any chance if not deagausing coil circuit ..

My son touched my television screen with a magnet in two spots leaving two discolored areas on the screen,purple and green in hue. I read many quick solutions to this problem on the net and none seemed to work completely,so what i did is took the same magnet that touched the screen and held it in my fist,then with TV on i waved my fist all around the screen working from the spots outward to the edges and this worked completely! Hope this helps someone..
