Guys thanks so much for this info on Bar 48 i had a similar issue of no power at sound bar,bought the power module from amazon and followed the instructions on how to wire it up,the new module powered up okay but still my soundabar didnt respond,i have tried everything on this thread but i gues mine had another issue.i really hate to throw in the towel by throwing it in the trash can.i really love the sound but i guess its time we part ways.
