You will need to replace the two convergence IC's. But if you do not have any solid state repair experience, play it safe and get a tech to assist you in this repair. Good Luck

    You can look on the printed circuit board for two black squares that start with STK. You can order them from MCM electronics. Then you have to get some heatsink compound and before you install the new IC's onto the printed circuit board, you rub the heat sink compound on the backs of the new IC's. Be very carefull when you are soldering or unsoldering, as it is very easy to ruin the printed circuit board with too much heat. If you have little or no soldering experience, have someone you know who does have soldering experience to do the soldering and unsoldering for you.

Fl231 replacement

ok first lets determine if the fuse is the poblem. do you have convergence option in the setup in customer menu. if you do then it will not be the fuse. if you have that option go into blue and red convergence. when you arrow over left or right up and down do the cross hairs move if they dont then it will be the power board(convergence)
