Ok first of all, the convergence board you are looking for is no longer available from Samsung, probably because of the large failure these boards are having. The only thing to do though would be to replace the convergence amp IC's on the convergence amp board. this will involve locating the convergence amp board, going to http://www.samsungparts.com, entering your model number, without the /xaa prefix. Locating the list of parts for this TV set, and getting the right convergence amp IC's for this TV set. The numbers for the convergence amps are STK-392-040. You will also need to get the service manual for this TV set to perform touchup convergence, as well as to realighn the magic focus into the memory of this TV set. If you have the ability to solder and unsolder, you should have no problem replacing thes convergence amp IC's. But i will have to say this, about 45% of these TV sets do still have a problem after the convergence IC's are replaced. this is usually due to the burnt ground return resustors on the convergence board, so be perpared to know how to read a scematic diagram in the service manual and to trouble shoot the board. There is no simple repair to this problem I'm afraid, with this Samsung TV set. But , if at any time, you feel lost in the repair of this set, do not continue, and call out a pro to assist you in the repair of this TV set. Good Luck with the repair of this TV set.

Horizontal lines can be cause by many things. One of which is the convergence module. $130.00 is a little high for something that can be caused by other things as well.

it need to be adjusted ,the converge is off track.there usually is a settings in the menu directy.should be a easy fix.if you cant have a service tech come and adjust it.the colors should come back when its adjusted.I think it savable

on your remote control click menue and than select sound and go from there

to tell which board you have there should be writing on the corner of the board in white.
