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!

I have the same problem on the same set. Is there a place where I can look up instructions on how to change the convergence board myself?
Thank You.
Hi i have a problem with the focus and convergence. auto focus will not correct as well as manual adjusting on the red color please help me i am not very familiar with rear projection screen, i need to know is the problem with the crt or with convergence board. what do you advice me to do please reply thanks Dennis.
I also have the same problem few days ago that the blue image cannot be focused. I will try to buy the board and see what happen.
The top 25% and the bottom 10% of the screen turns to yellow with an arch. Therefore, only the middle of the screen with an oval shape has somewhat the correct colors and it's "framed" with this yellow hue. Also, I notice the image of the yellow regions repeats itself towards the middle of the screen in blue. Unplugged the tv for couple hours, replugged and turned on tv. The screen first look cured but the discoloration appeared again in couple of minutes.
I have a HCN4426W Samsung projection tv and recently the red tube picture has been arcing downward on the left and right sides of the screen.
