I have a Samsung HC-P4752W with a convergence problem (red is sagging). I believe I need to replace the STK392-110 IC however from my browsing on various forums, I have heard that this IC has been superceded with STK392-150. Does anyone know if this is true for my particular model? Is there any other info I need to know? Or do I need to buy any other parts to complete this repair (besides the pico fuse)?
