I have a samsung HCL473w that started to have convergence problem. I have this red bow on the top of the screen and red, green and blue are not aligned. I tried manual adjustment but nothing will move. Also, perfect focus says "No sensor data". Based on threads in this forum, I conclude that I need to replace the IC board. I ordered it from the partstore.com and waiting for it arrive now.
I do have one issue though. I don't know how to take the old board out? From the back, I see that board is secured with 3 screws on the right. The screw near the front of the TV is almost impossible to get to. How am I suppose to remove this screw? Do I have to remove this big thing with the bulb right above it as well? Also, even if I remove all screws, how do I slide it out? It's blocked at the both ends with these plastics sticking out.
Perhaps the service manual may help. If anyone has one to share, please send me a copy to [email protected].
Thanks in advance.
