CONVERGENCE? I have the dreaded convergence problem. I noticed that the blue line is curved at the bottom and seems to be lower on the left side of the screen. When trying to use the manual adjustment I have noticed that the Red can be moved up,down, left and right. When trying to adjust the blue I can make it move left and right but will not move up and down. I just replaced both of the STK392-110 IC's last night. The condition is exactly the same as before. I did not seen any burnt resistors,cracks or other hot spots. This TV is 6yrs old and has been working great until this. Could there be a problem with the CRT? Is there a good way of checking them to confirm? Any and all help is very much appreciated

well if the blue can move in all directions then you are probably fixed. does the blue move in both directions at all nine points? but you can not get close enough? If this is the case you may need to do the alignment in the service menu. The possibility of damaging those IC's is remote but I will never say impossible in this line of work. Swapping the yoke plugs will isolate the yokes but your problem is not the tubes and i really doubt the yoke, that is VERY uncommon. Major adjustment in the service menu is not that uncommon after an amp job. I would move the rings back they really shouldn't be moved, they are basically used for centering so use the center cross in the customer convergence menu to adjust them back. To enter the service menu, mute the TV (push it twice if it has the half mute feature) and then press and hold the mute button again on the remote, while you are holding it press the menu button on the TV. You will see a small "s" appear in the right corner of the screen. now press the menu button on the remote and the "s" will dissappear on the right and you will see an adjustment on the left, probably "rcut". Now press the number 7 (NOT ANYTHING ELSE!!). You should now see a large cross hatch covering the screen with a curser somewhere. The number 5 will freeze the curser for adjustment or start it flashing to move it to the next spot. While it is solid you can press the number 3 to change colors. and press 8,4,6,2 to adjust the selected color. While it is flashing 8,4,6,2 will move the curser around the screen. Only adjust the blue and notice that areas around the spot you are adjusting are also being effected. It takes a little patience and a lot of getting used to as you can adjust one spot and bring another out so you have to correct it and then go back to the original spot and over and over again. do yourself a favor and beginm with small changes. Good luck and let me know how its coming. well if the blue can move in all directions then you are probably fixed. does the blue move in both directions at all nine points? but you can not get close enough?
