I have a Samsung HC-P4241W. I opened the back and pulled the board that has the IC STK chips on it. I desoldered them (2 STK 394-250 chips) and replaced them. The solders are clean and not crossing over. I located 4 green pico fuses in various locations around the board, they all test fine for continuity.
Even after replacing the STK's the TV has an obvious image convergence issue even after the repair. Does anyone have a service manual that I could look at? Any suggestions as to where else I should look to fix this thing?
Any help would be appreciated...I'm out of ideas.
I changed the two convergence IC's on this unit. I tested 4 pico fuses and they all had continuity...still not fixed. Any other ideas on what might be wrong with this unit?
