Question about Samsung HCN4226W 42" Rear Projection HDTV-Ready Television

HCN4226W 42 in. Rear Projection... Problem: TOO HOT

The set had blown the convergence module, at that time I also figured I would replace the CRT coolant and remove all boards and clean them all up. All work was done and the TV works fine, the only thing is the transistor that runs the flyback and the convergence module runs HOT, I am worried the same break down will occour, is there any info on how to get the set to run cooler so it will last longer, maybe manually adjust the convergence on CRT's  or a larger heat sink. Any tune up help would be great.

I have a samsung rear projection hcn4226w the picture has a couple horizontal distorted spots on it and the box that says what input you are using there are two instead of one

You have a convergence problem. It is much easier to replace the whole module, than just the STK's, no soldering required..It is so easy to do and electronics skill level is not required.One screw and five connections(plug in) is all it takes.The part number you need to order is BP95-00142E convergence amp. I would google search it and find it at the lowest cost

Coloring is off and there is a ghosting effect


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. Is one site, might have to purchase one.
