Trying to troubleshoot a broken soundbar too and am stuck at the same point you are. In another comment you mentioned an IC that has cracked. Which one was it? Who knows, maybe one of us will find a fix since it is very common for those soundbars to break like this. Although it might be a different cause for each of us… but maybe not. Did you try the reset procedure? Take it off power for 1h then plug it in while holding the power button down and keep holding it for 60 seconds. Then try to turn it in. Unplug it, and re-plug it and try to turn it on.

Hey @constantinflux The chip i replaced was Q6 Labeled N7S2 or N752.. hard to tell. the crack was on the left side of the chip. I did attempt the reset procedure and it did not help. I still have hope for this but I've spent so much time on it. Currently its collecting all the dust in the workshop to hopefully be revived one day

@@TestingWithMike There is a Video o YT by an Italian person that iirc replaced the mosfet (?) that is responsible for starting the logic and also swapped some caps around it. I’ll post the link if I find it. Might help you as well!

@@TestingWithMike Found the video I mentioned: kzbin.info/www/bejne/pGjSZYyEhaiUqsUsi=xBcWTbgd6k9ss6AM you can turn on subtitles and switch to English subtitles. There are two more vids on his channel from a year ago where he is fixing another soundbar. Might be useful. I’ll check the mosfet in mine on Sunday. Maybe it’s faulty in mine too, who knows. Thanks for your video!

By the way, I'm having the same problem of the soundbar not lighting. It happened after a cleaner had used the extension where the sounbar was for a vacuum machine. The other devices that shared the anti-surge extension are okay though.

Every chip has a marking on it to show pin 1. In this case, it's the top right indicated by a circle. This issue is very common and I have attempted to repair this while filming part 2. I found a cracked chip and even after replacing it, it still does not power on. Unfortunately, even with the schematics I cannot isolate the issue. I've had to shelf this for now until I have more time to poke away at it.
