Hi all,

I'm not a technician, so this maybe pointless. I have an LG Soundbar and sub, the soundbar is fine, it's the BT sub that is the problem.
When I opened up the back I found a small blue capacitor that had blown off, I replaced this.
I have a meter and it looks like the SMPS is creating power, i just don't know why the element died.

I know the info is vague, If needed I can upload pics and provide more information. I just thought it was worth trying to look at before buying a new one, too much is thrown away these days.

Hi, yes there was a small burn mark. The 250v fuse is is, I've also replaced a couple of resistors which I thought were a bit suss.
It seems to output power to the board.
