 Further repair would take some troubleshooting...at this point I would be verifying the info that you gave above and likely getting out my scope if it is correct. My guess is that you missed something in the repair, or perhaps you do not have complete info on how to adjust the convergence. |
The set I'm working on is a 55" Samsung HCM5525W. After taking it apart a second time, I closely examined the board around the STKs. I found two pico fuses that I hadn't noticed before. I found them by the marking on the underside of the board. They were both green and looked like resistors without the indentifying bands. I ohmed both of them, and one was open. It was labeled FD101S on my board. So I replaced it, and finally I was able to correct the convergence. The fuse probably blew when the STKs went out, and burnt the resistors.
For those who are having trouble correcting convergence after replacing the convergence ICs, look for a sine wave symbol on the underside of the board. That indicates a fuse, and is usually soldered on the board like a resistor.
Thanks again lcaillo!
