I have a rear proj. with the green totally out of place. From all my research it seems to be a convergance problem. I have been quoted $500 aus to repair but I would rather buy a plasma than pay that. I have a supplier who can provide a convergance module for $130 and I have SECURITY ELECTRONICS BACKROUND so i can change boards easily. My info is that it is just a board with one screw and plugs.
My problem is I want to be certain I give the correct part number, so what does the board look like exactly and does anyone know the number from their manuals . I think Ive spotted it but want to be sure.
Any help would be greatly appreciated, thanks , Steve
I have a samsung tantus crt rear proj. Model number (from rear panel) SP48T5HP. I've got a red arc in the top left section and the the alignment seems to be off. text on the screen is ok for the other bulbs just the red is off place. May just be the lens alignment but i'm not too sure, don't want to touch anything without knowing anything. If anyone's got any suggestions that would be great.

Re: rear projection problem. samsung sp48t5hp
The board sits up high above the larger boards....one screw &
four plugs sounds right. Bad part is STK392-040. If you decide
to repair----replace both IC's for reliability. I use Panasonic brand
to eliminate re-calls. Re-set alignment....done....T.

Hello: Have you had your convergence IC's replaced. The Green is the Center Tube and does not adjust in customer mode. Seems the other two colors is whats out of place. Have the Convergence IC's Replaced and this should solve your problem
hi, this is the early signs of convergence board chip failure. you will need to replace this board in order to correct the collaboration feature. the convergence is responsible for regulating the RGB stream in you set. if it is malfunctioning, you will not be able to regulate the red blue green streams.
I have a Samsung HCM5535W rear projection TV that had pretty much the exact same problem-- a green halo around bright white images. I researched it on the net, and determined the most likely problem was with the convergence STK-ICs, or the convergence board. I bought a replacement board with the STK ICs and installed it, but no luck, the problem persisted. I decided to mess with the manual focus adjustment on the green crt (i was seeing a green halo), and that fixed it. As it turns out, no replacement parts were necessary to fix the problem in the first place. Hope this helps somebody out there.
