There's three liquid cooled CRTs, one for each color. You have to replace all three of them at once if you want to ever get the color adjusted right again, and usually the burn is on all three. They're usually about 300 bucks each and you have to do a full alignment after replacement. You might get lucky and find a set of serviceable used tubes. |
