Hello, I posted this issue about my Samsung 42" rear projection HDTV (Samsung HCN4226W.). Your solution sounds good but I have one question, the part number you listed was:
BP95-00142E convergence amp
When I do a search on that, the part number comes up as a convergance board. There is an amp with part number:
BP94-00155A Amp
It is the amp I need, not the board, correct? Thank you for your help.
Re: 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:

sounds like you are haveing an issue with th color wheel timing. either the color wheel is bad or the dmd board is bad.only way to know is to have a technician look at it.
The convergence IC has gone out and is located on the Main bd or the Power supply bd depending on the specific model and must be replaced and a Full convergence alignment must be performed to return your tv to a watchable condition. Only a Samsung trained tech can do this.
You have a convergence problem.You can replace this module cheaper than it can be repaired.It is so easy to do and electronics skill level is not required.If you can unplug the TV and remove the rear cover,then you can do this repair yourself.1 screw and 5 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 to you.Good luck and please rate my information.
My 5 year old Samsung HCN4226W is not coming on (no picture and no sound). When pressing the "ON" button, I can hear a "click" like it wants to come on, but nothing happens. HEL
you can get a replacement deflection board at the following link. If you dont know which one your model requires leave them a email with your model number and what youre needing they respond quickly and will provide the proper one for your model. http://servicemanuals.vstore.ca/
I WOULD RATHER THINK IT IS ONE OF THE CINVERGENCE AMPLIFIER & DRIVER IC,S
A REAR PROJECTION TV NORMALY HAS 2 OF THEM AND THEY ARE THE SAME AND NORMALLY THE NUMBER ON THE IC STARTS WITH "STR *****" SWAPING THE TWO AROUND WOULD PROVE THAT YOU GOT A PROBLEM ON ONE OF THEM,THEN JUST GET 2 NEW IC'C
THE SYMPTOM THAT YOU ARE DESCRYBING IS MOST LIKELY THE IC'S
HOPE THIS HELPS
