Question about Samsung HC-P4363W 43 in. TV/DVD Combo
You have a failure in the convergence circuit. To confirm this, go the customer convergence menu where it allows you to move red and blue crosshairs to align the colors. If the crosshairs fail to move then you probably have bad convergence IC's and/or some open resistors next to them. You can identify the convergence IC's as two large black chips mounted on a heat sink with screws. There will be an STK number on them, probably STK392-120 I think on that model (though not sure without the manual in hand). They will both need replacing with the same STK number as the one written on it. You need to check for open resistors too. They will be lined up infront of the IC's in a row and all should be < 5 ohm in value. You need to unplug all three CRT yokes from the convergence PCB when you measure these as you will read the resistance of the yoke and fail to detect an open resistor otherwise. If any need replaced they must be replaced with exactly the same value - they are critical.
