Screen green and purple in two corners

The chances of a damaged yolk is slim but possible. It sounds more like you've set up a new set of speakers either side of the set. Or maybe you have a VCR, CVD or setop box sitting on top of the set.

Electro magnetic fields can cause plenty of funny color problems with CRT tubes so try to kepp unshielded speakers at least 2 feet away from a TV and any other electrical appliance at least a foot.

By the way I had a TV which exhibited a beautiful color problem, it took a while but we tracked it down to the housewife turning her vacuum cleaner off right next to the TV to change power sockets and then switching the vacuum cleaner back on. Right next to a floor standing 26" TV. Her husband bought her a long extension cord :-)

I am in agreement with the second solution. TVs, when moved from one location to another have a tendency to show color patches in the corners. A few days of usage, and the auto degaussing circuits will clear the problem. Also make sure that there are no Magnet Sources nearby (Un sheilded Speakers, some Power supply of amplifiers, A 2-in-1 music system, your kids walky-talky toy, etc.)

your gonna need to degauss the tube with a small coil of wire. Maybe a repair shop will let you borrow or rent a degaussing coil. or try to unplug the set over night and try pluging back in in the n am and see if it took any amount of discolorazion away. if it didnt it could be the deflection yolk sahifted on the neck of the crt or the shadow mask inside the tube is damaged.. Good Luck

Hello, i have also came across with the same problem. To solve this problem you have to purchase some small magnetic chips ( used over the back of the picture tube, if you notice the picture tube carefully, you will see some black magnetic chips pasted on the picture tube, which are used to control the color of the pic. tube) which are easily available in the market. Bring that magnetic chips and move over the back of the picture tube and where you see the color pacth gone just paste it there with tape. Do it on both the sides and the color pacth will be gone. For this you have to keep the tv on. Please be carefull while doing this, if you are not expert do not try to open the TV
