Question about Samsung HC-R4755W 47" HDTV
My TV convergence is messed up and looks 3D like so many others.
From searching this site, I found the most likely problem is my convergence IC's. The pico fuse supplying the left IC was blown however the right one wasn't and none of my resistors seemed to be blown. I replaced both STK392-040's and the pico fuse on the left.
When I powered up the tv, it looked exactly the same as before the repair and the right pico fuse was blown this time.
Does anyone have a clue of what could be the problem.
I also would like to know which resistors usually go out with the IC's.
The old IC's had the letters B2H12 at the top right and the new ones have B3C25.
The problem is likely to be the digital convergence board that generates the convergence signal that is amplified by the output ICs.
