My TV is not working! Please help!

I have a Samsung HC-PA4363 TV and it is not working properly. Recently it started having a blue line on the left side of the screen and yellow under it. The commercial's letter has a shadow of blue around the letters. I am not sure what is going on but I want to try to troubleshoot to save me a bit of money. Thank you so much.

well you should have your adjustment checked,,
then your vertical controll ic. and circuit..

more than likely is an asjustment problem, just open it up and look for the controlls and try adjusting it your self, if your unable to do this take it to a local technician

Top part of tv has a colour problem, its faded and looks like its shaded

if picture is not having a 3d look were red green and blue does not converge properly then it could be as simple as a dirty mirror but unfortunately either you have a convergence issue or a cloudy coolant fluid or a bad focus block

    Hi I have a samsung tx32766 aprox 42 in tv that was manufactured in July 1999. It was working great and then a line came through the middle with no picture and it keeps shutting off. I'm just wondering if it is worth having a service call.

    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.
