Hello fellow audioholics, sound bar repair update. the first replacement mb had a broken ribbon cable retainer clip and bent pins. the seller sent another board and sadly the sound bar is showing no signs of life. I checked for proper voltage to the new mb, but that's all i can decipher. I disconnected all tertiary boards one by one trying to eliminate any chance of a downline short, no luck.
I did find a copy of the manual (thanks for the hint), but see no fuses or way to jumpstart the new board back to life. Any techs out there your expertise would be appreciated.
I am putting together a dim bulb and will try to measure residual power drain, should be below .5ma?
thanks,
