Re: convergence

If you look in the back of the set, you have 2 big boards at the bottom, the one on the left has the convergence amps on it. These are the STK's standing up on a heatsink. These need to be replaced and the return resistors also in that area. You can look for part # on the IC's and visit MCMelectronics, bluestar-online, tritronics, etc and find the part. Be careful if you don't know how to solder the IC's out and the new ones in.

I am getting a blurry picture that kinda makes it look like a 3d movie without the glasses on with alot of blue

The tv have a problems known as a convergence pictures problems.Tv have any colors lines R,G,B mis alignments,tv have any colors shadows pictures or have a 3D pictures look alike?Yes,than the tv convergence board it is the causes and already dead to have many of these convergence pictures problems.The tv convergence board must have to be repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures many problems.The tvs shops will cost u like $300-$350 for parts and labors.

My tv has double writing and picture and the picture has alot of red and green in it what should I do or what does that mean

Look at some photos if they show your problem you have a convergence trouble.

Total parts cost if parts purchased on EBAY will be under 30 dollars.

I can step you through the fix but if convergence it means both of the STK-392-110 CHIPS need to be replaced.

The hard part here is getting at them--I can tell you the best way to do this as I have fixed over 1,000 sets with this kind of problem.

Other than the chips there are a few resistors around them that need to be checked--easy and they are cheap parts if needed.

Let me know your skill--I will post photo of the chips and what typical convergence problems look like.

If this information is helpful rate this solution as "very helpful" as I do this here for free.

The green color is off. I am thinking that it is the auto convergence. I want to try to fix it my self (I love to do these kind of things) but I do not want to buy the wrong part.

This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$300
To Find the IC's look for 1 or 2 large (4in x4inx1in) aluminium heat sinks. the part # is labelled on the face of the IC itself

Had the ICs burn out

You can get them at this distributor.
But you didn't say which ICs you need.
If the convergence IC have failed they are usually other things to check. Write an exact discription of the problem.

Samsung hcn4226wx/xaa red color out of focus

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, 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.
