PCB CODE to P/N Identification ?
Posted: Mon Apr 02, 2012 7:12 pm
Some time ago I needed to replace the Digital board on my set. Working through Justanswers at the time, I was given a Samsung Service Bulletin that stated that the "NEW" Digital Board which replaced the original board, also required that the Analog PCB be changed to a different board as well to avoid synch problems between the picture and audio. Well, like a good soldier, I ordered both of the new boards and installed them ( BP94-00434A, BP94-00385A). After putting the set back in place I discovered that I had no audio at all! Being disgusted with it all at the time, I left it and we have used external sound ever since. Recently, I had the CW go out, so now that I have the set apart I would like to resolve the audio issue. After checking all connections to the Analog board, I could find nothing wrong. I am now suspecting that I was not given the correct Analog board (iffy ebay source), or a bad board.
Since neither of the boards have a sticker or anything showing the P/Ns referenced above, I am hoping that someone on this forum has a source that shows the correct PCB code for the two replacement part numbers? If one or both of the boards are wrong and incompatible, that would explain the loss of sound. I believe the Digital board is probably correct since the picture was great and it came from a reputable parts supplier, but mistakes can happen. Neither Samsung or the sellers could help with this question.
