1st time poster, please don't hit me.
I am trying to fix my home cinema problem. the HT-AS1 made by Samsung. board number is AH41-01062A rev 00. it developed crackling sound coming from one of the channels. I initially thought it would be just a loose wire. no it wasn't. second guess was a capacitor somewhere on the board. no it wasn't (at least none that visibly leaked). next course of action was replacing optical-in port. managed no problems. and while de soldering the port I had to flip the board over to solder the joints. that's when I discovered the probable cause of the problem. one of the induction coils lost its shield. this board uses some sort of induction coil I am unable to find anywhere. there is some sort of part number on the outside of the shield 1310LP and if I flip it over, there is number 15 at the base.
I realize that to measure inductors, I would have to have oscilloscope. no chance of getting that. maybe someone out here would know where to get them or perhaps even have some of these on stock...
can someone please help me out? I am trying to fix everything that is broken in my household and for all my friends. and although I can afford to replace the sound system, it would be such a waste, as this one has great sound(when it works that is)…
thanks to all that will be able to help one or other way.
