Hello Sir,

have the same problem,as others do, with the convergence board. Do you sell this board (BP95-00142E) and can I get the alignment manual file?

Thanks in advance,

    TV still displays, but red, blue and green are totally separate. I see three images. This set was new in May of 2003, and is out of warranty. Perfect Focus does not correct problem, and manually adjusting convergence does not work. If I need a new board, what should it cost to have one installed? Thanks!

    I have the same problem. Three seperate images, green, red, blue. I had it at a repair shop and they said it was a CRT problem. After 3 weeks, he decided he wouldn't give me an estimate or repair the TV. We're getting it back today and we don't know if we should just give up on it or try to get it fixed.

SAMSUNG Convergence Board

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

Open the back of the TV. The board is in front of you, a small separate board with small plugs attached. If you think you are competent enough to remove it and replace it without damage to yourself or the TV, go for it.
Website below gives some description of costs with in home repair of convergence problems.

If you live around Calgary, Alberta try me.
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

Coloring is off and there is a ghosting effect


Hello,

Part # BP95-00142E is the correct convergence amp board for a model # HCN4226W. Part # BP94-00155A is listed as a "CG Amp assembly board" also, but is not correct for a model # HCN4226W. They are both basically convergence amp boards. Here's a link to order the original Samsung covergence amp board for this model (HCN4226W) from a major parts distributor:

Samsung HCN4226W Service Menu?? For convergence issue????


The resistors on the new module are not 100% Identical in resistance to the originals on your board, to access the svc menu you will want a service manual and will require some patience. It can be tricky I would personally call a repairman with convergence in mind. Or order a manual and read the conv section several times. http://www.eserviceinfo.com/index.php?what=search2 Is one site, might have to purchase one.

Convergence problem?


That board, P/N Bp94-00155a should fix the problem and be fairly easy to replace. Make sure you unplug the TV before starting the repair though. Duh!
