Dead Samsung

I don't recommend working on the TV unless you have some experience and knowledge relating to the safety issues and electronic repair. Most rookies will not successfully complete the repair and probably do more harm than good.

Sometimes when the convergence chips fail, the TV senses the changed load condition and shuts down.

Unplugging the blue, red or green convergence connector on the convergence board removes the overload condition if the IC is shorted and allows the tv to run, with one color missing.

This is done with the tv unplugged. Then plugged in and turned on to see if it starts. Turn off immediately if you here it start.

Now you know if convergence failure caused the shutdown. You can repair the convergence circuit if that is the problem.

If this has no affect, then you could have a number of different faults in Vertical output, Power Supply or HV circuits that require the expertise of a qualified service person. This would be a bench repair in most shops.

If you live around Calgary, Alberta try me instead:

Or try to the find the repairperson part of this website (on the Homepage) and search postal code. Maybe you will be lucky and someone from your area is listed for Projection TV repair.

Most rookies doing this job will cause damage and not be successful. They will pay double for someone to fix their mess or end up scrapping the TV. It is not a simple task. It is more difficult than batteries on a remote.

Good Luck

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 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.

Another Question Please.


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.
